Ford 7.3L Power Stroke (1999-2003) :: F350 DRW 4x4 Transmission Temp High
I will start off with saying I am posting this for my dad. His truck is a 1999 F350 crew cab DRW 4x4 auto 7.3 with about 189K miles on it. He is leaving wednesday on a cross country road trip pulling a 40FT 5th wheel (no idea the weight but the thing is huge). He has glowshift gauges installed, one of which is the trans temp gauge. I believe the transmissions on these are 4R100, but I am not positive about that, but I'm sure many people here will know. He just told me that he had the mechanic he goes to replace the pan gasket on the transmission because it leaked quite a bit, just as a precaution. He also had them replace the brake booster as it was leaking inside by the brake pedal. When he got it back, he said he was driving it, and the temperature started going up to I believe 220 degrees not pulling anything. He said since he installed the gauges it has been between 180-190, and it jumped to 220.
What this could be. I have read that the TFT sensor can cause this issue, but it would throw a code and possibly go into limp mode. He has no check engine light and it was driving just fine. So the temperature is just all of a sudden high. Fluid level is fine, was checked after about an hour of driving, is red, and doesn't smell bad. I am suspecting the temperature isn't actually hotter, so there is another issue. It's only a big deal now because in a few days he will be dragging a huge 5th wheel behind him.
Last year, we towed some pile of crap 5th wheel down to our city for somebody with his truck, and we had to pull over halfway back because it started to smell like something burning. We think it was the trailer, as the brakes were questionable on them. When we got it to the people we were delivering it to, when we left, it wouldn't shift passed 2nd gear. He only lived a few miles from there, so he drove it home, parked it, then went out the next day and it was fine. He had the fluid flushed later and that issue hasn't come back since. No other work was performed on it since the pan gasket a few days ago. I am not sure if they are related being a year apart, but figured I'd mention it anyways.
Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 - High Idle / Over Drive Light Started Blinking
OK, truck is 2000 F350. I am heading on a 2000 mile roadtrip to Yellowstone for my wife's 40th birthday in two days. What was our rock of a vehicle is now causing me severe anxiety.
Over the last few days the truck has been difficult to start - almost stops turning over as if the batteries were low. So I ignored it because if I plug it in, it starts fine and if I drive it and it gets hot - it starts fine.
Tonight while driving - I noticed a high idle and then it went to normal - I thought it was weird and a few miles later at a stop sign it struggled at idle, sort of loping but not romping very high and the over drive light started blinking. When I got home when I went from drive to neutral it goes to high idle and then the overdrive light blinks. The first time it blinked it went off when I pressed the OD button - but now it continues to blink.
Would low batteries be the root cause of this? I will continue my search for blinking OD light but I thought I would get this in the queue in case this is bigger than I can handle. I have 48 hours to resolve this issue - leaving Wednesday early morning.
Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 - Missing After Start Up - High Idle - Got Codes P1316 / P1211?
Well, long story is that I starting have problems with my 2000 F350 Dually 7.3 PSD about 6 months ago ( ~10K miles ago ). I have sunk almost 5K$ in mechanics and the problem is still present.
By troubleshoot, I do not mean try this, try this, as that has been what is happening. I mean making test measurements and diagnostics. I am fairly mechanically inclined, but I am no mechanic. Looking for primers on how the 7.3 PSD works.
Symptoms: After the truck sits 12 to 14 hours, it starts and idles fine ( ~ 700 RPM on the 'Dash Tach' ) just as it has always done. During the first 5 miles of driving it, the SES light comes on and it sputters, stalls, and vibrates as if a couple of the injectors are not firing. It then clears up and the SES light goes out, except that it idles at about 1200 RPM ( 'Dash Tach' ).
It runs fine like this the rest of the day, If I shut it down it will start right up and run fine, but it has the high idles. Only if it is shut down longer than 12 to 16 hours do the symptoms, other than the high idle, reappear. The high idle is constant. Also mpg have fallen ( 13 opposed to 16 ).
It does not seem to be related to ambient temperature, or the amount of warm-up idle. I have idled it for three hours on startup and it is fine, until I drive the first 5 miles or so.
Now, I have had three mechanics work on it and they have replaced: the ICP sensor ( 3 times ), the Fuel filter ( twice ), drained, flushed and refilled the HPOP, replaced both sides of the valve cover wiring harness, put in a new IDM, fuel heater, CPS sensor ( 3 times ), fuel pump in fuel tank, EBPV ( not sure what this is ), and the last straw was saying the injectors needed to be replaced ( or at least the O-rings, but while we are in there you might as well ... ).
I bought a cheap code reader and it says: P1316 & P1211. I believe these are the same codes since day 1.
Ford 7.3L Power Stroke (1999-2003) :: A/C Blows Through Defrost Vent Only
My 99' started o blow air only through the defrost vent today, and won't go through any of the other vents. I think this happens when your vacuum pump goes bad or there is a leak, correct? If so, how can I test these to figure out the problem.

My 01 ac has worked just fine up until today. I got in this morning to leave the house and the air was only coming out of the defrost vents. I tried playing with the controls to get it to switch but couldn't. I assume its a vacuum leak, but where do I need to start looking?

I have a 03 F-350, 7.3L. There is a slow oil leak that only leaks after I've run the truck. In other words, it doesn't just sit and leak overnight. I'll park it after running, and the next morning I'll notice a small pool of oil, approximately 2" in diameter. The leak appears to be coming from the oil pan area. I degreased the entire oil pan area to get a better visual of where the leak is coming from. I can see oil trailing down the front of the oil pan and the rear of the oil pan. Does this sound like the gasket? Or, what else could it be? I'm praying its not as bad as I think and need to replace the gasket.

My issue I'm having - 2002 F350 7.3L has an 8 inch bds lift with 37/13.50 tires. I realize these tires are big but... while driving 100kms/hr or 60 miles per hour and I hit the gas the truck barely wants to move (without pulling a load). Thought maybe a turbo but I have no mechanical skills so here I am!
2nd issue, there's a bullydog chip in that truck when I bought it. he said he always ran it on extreme. I found it puffs way to much black when on extreme and on performance it seems a lot better so that's where I have it?.
3rd issue, the transmission gauge on the dash goes into red when climbing up hills ( I live in the rocky mountains so a lot!) but the bullydog chip says the tranny is only at its hottest 140C? I don't believe that's to hot but I do believe my truck is derating a little while the tranny gauge on the dash is in the red? is there any quick fixes out there for these issues.
Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - No Power Especially While Towing
I just bought a 2001 F350 diesel with 120k miles on it a couple weeks ago. Friday I headed out to Oregon with my 16 foot enclosed trailer filled with jet skis (about 4-5k pounds) for a competition. A few minutes after being on the freeway I noticed the truck did not have good power. About 30 min later while climbing a steep grade the truck almost went dead.
I started at 60mph and by the time I got to the top i was at 15mph with the throttle pinned. the motor sounded funny and shook the truck more then normal. After wards on the down side of the grade the truck started to act normal. I took it to my buddies house and switched trucks because I didn't trust if for the 13 hour drive.
Today I talked to a mechanic at the dealership and he said that it sounded like injector o-rings to him. I went home, pulled the valve covers and started the motor to see if anything is leaking. steam was coming from the valve area and the down spouts on the injectors was flowing oil. The thing that looked especially abnormal was one of the injectors looked like fuel was dribbling from it. I don't know if that is a problem or not. I couldn't tell if it was fuel or oil but no other injectors had fluid coming out near the wire connections.

New to the forums, not new to fords. 1999 F350 7.3L Diesel. This has been a work truck and has seen multiple devices in and out over the years. I removed the last crap for GPS tracking etc from the last owners. The truck has worked well for a long time since until...
I'm moving slowly to a different state and so the truck got parked for 2 months. went to start it and nothing. the dash comes on and all the lights come on but when you turn the key to start the power drops and nothing.
Testing so far:
replaced the fender Solenoid
tested the starter motor and solenoid -passed
replaced the ignition switch
tested continuity of the hot and ground wires to the fender and starter and everything passed
When I shorted across the fender solenoid the starter works and tries to start the truck (unsuccessfully so far)
So the wire that goes to the fender solenoid is not working and where to trace it to and what needs to be fixed. Is there a relay or fuse besides number 30 that is in the way? where does the magical wire go so i can check its continuity?
I am stuck 800 miles from where i need to be and I am stuck here. I don't have the cash to get a mechanic and my mechanic friends are stumped. I do have a Snapon modus tester, what to do with it.
FYI the batteries are new and fully charged.

I have a 99 f350 Lariat. I was wondering if there is such thing as a cabin air filter on these trucks my a/c is blowing and its cold just not blowing hard enough like it used to if there is not a cabin filter is there a way to clean the evap coil. I always figured youd have to after so long since you always got dirt and what not in the truck the coil should stop up after so long its got to happen but how hard would it be to clean it?

I have a 1999 f350 with a 7.3l in it. A week ago I stopped at the pump and topped of my tank and when I went to restart it it it would crank and not fire. I had it towed and replaced the cam sensor with an aftermarket one. It ran but it would cut out when I got into the throttle and wouldn't start when hot. I bought another aftermarket one and it did the same thing. I tested the hpop pressure at the back of each head and everything checked out perfect while running. I replaced the Ipr with no luck.
And I also tried unplugging the icp sensor and it didn't make a difference. It starts perfect when cold but when it's hot and you shut if off it will just crank. I replaced the cam sensor once again with a ford one and everything worked perfect and it started no problem for a day then started doing the same thing again. I've taken a close look at all the wiring on the motor and it looks good. Battery's and starter are new. All the cylinder contributions test good as well as the injector buzz test. I'm not noticing any change in oil. Oil was changed 800 miles ago
Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Power Loss / Hard To Hold The Speed?
I drive a new to me 2005 F350, he has a 2001 F350. While we were talking he said he didn't think his pickup had the power it should have. He pulls a 5th wheel camper that weighs around 8000 pounds fully loaded. He said it takes a couple of miles to get to 55 mph, and it is hard to hold the speed. It doesn't have the power it did when he first got it last year. He was told that a diesel is slow getting started. He rode with me in mine, when I dropped it about half throttle to pass a slow car he said he could tell mine had way more power.
His check engine light is not on, it starts good both when hot and when cold. It runs smooth, no miss as far as I can tell listening to it. What are some common issues that could cause this? He did just change the oil and fuel filters, not sure about the air filter. He said the power loss came before he serviced the engine, and did not improve after the fuel filter change. Where to start? He was also told to check the filter inside of his fuel tank, so he is getting ready to drop his tank.
Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Power Loss And Almost Shut Down At Random Times
I have a 2001 F350 7.3 the truck will at random times loose power and almost shut down. A while back I had an issue with the uvch plugs and changed that out. Truck ran fine till I got some dirty fuel from a diesel tank at my friends farm. I did the hutch mod cleaned the tank and now have a frame mounted screw on filter before the pump. I cleaned the fuel bowl and changed the filter. Fuel pressure stays at 59psi and drops to 56psi wot. The truck is tuned with an edge programmer. After these mods the truck ran awesome for over 2000 miles. Now it has the above stated problem. I have fuel and hpop guages along with egt and boost. During the problem egts will increase rapidly and it seems like it is starving for fuel.
Hpop gauge reads 3300psi or above during wot and shows good pressure during these mishaps. I have auto Enginuity and I get a different reading at wot of only 2600 psi. The hpop gauge is tapped into the icp sensor per instructions and has been installed this way for a while with no issues. The tune has been on the truck for over 40000 miles. The only thing that I can come up with is it will occasionally throw a p1211 under wot or pulling my Gooseneck Dump Trailer when loaded. However it acts up sometimes and doesn't throw the code. Sometimes you can shut it off and start it back up and it's fine other times it will last for the whole day. My only guess is low pressure from the hpop but I don't reflect this from my gauge only on AE at wot. Wouldn't a bad pump act up all the time? Am I correct to think it is just the ipr?
Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Heat Seat Power Wire Location
I have a 2001 F350 XLT with cloth seats. In 2003 I upgraded those seats to power seats.
- When I upgraded to power seats I did not run a new power wire. Since my 2001 was at least fused for power and heated seats I located the Power seat 30amp power wire.
- That wire is located on engine compartment fuse #15 (Circuit 5298 as I recall) and Dark Green. It comes through the firewall and runs down the drivers side kick panel along the floor and then intersects with the power and ground seat belt wires that ran under the seat.
- The ground wire was coiled and attached to a ground stud behind the drivers side kick panel.
About a month ago I had a mouse get in and chew my seat wiring to shreds. I built my own harness and am good to go there, however since I had these seats all apart I decided to replace the foam and add HEAT.
So that brings me to the specific question. In the engine compartment fuse box, there is a 30amp positive wire for Heated seats. My schematic says it is a 14 gauge wire RD/BK on circuit 1153.
Where in the heck is this wire? I have literally tore the dash apart looking for this wire.
- I have verified the following with my fluke continuity tester.
- It is not part of the four customer access wires that drop on the right side of the interior fuse panel.
- It is not part of the tow wire bundle.
- I have checked the bundle that the Dark Green Power seat wire is in and there are no RD/BK wires in that bundle. I also poked the other 2 14 gauge (Yellow/Blue) wires in that bundle and verified they are not them.
-I have checked the three wire bundles behind the passenger side glove box and was unable to locate.
- I have verified it is not stored behind the compartment below the cigarette lighter.
I am looking for info which wire I am talking about and knows where Ford stored them when not used by having the XLT Trim with cloth seats. Yes I am aware that I can run an additional wire with a 30 amp fuse to the batter, but I would prefer to use the system and fuse that was designed for this.
