View 7 RepliesFord F-150 - 1997-2003 :: Service Engine Light Comes On
2001 F150, 5.4L gas, 4wd, stock, 217k miles, auto trans. Bought it used about 4 years back.
Currently away from home base. Left Saturday for a 600+ mile trip. All fluid levels are good. Truck has been reliable. No major issues other than an alarm malfunction a while back which got sorted.
About 90 miles into the trip down the highway, the service engine light comes on. Hmm. At the next fuel stop I tanked up. Started and it was a bit rough the first few seconds and then settled. Seemed to have an engine noise I had not heard before.
Pulled over in the station and popped the hood. Oil good. Coolant fine. Power steering fine. Listening to it I could definitely hear an unusual sort of "ghost" like sound. Hard to describe. Sort of like a low "woooooo." It was low, but definitely there and not normal. Could be unrelated to the engine light. Pulling out of the station the sound varied and got louder with slight acceleration. Possibly beginning of an accessory bearing meltdown?
No acceleration or dying issues. Got back on the highway and kept on trucking for 600+ miles. No running issues. No shifting issues. Ghost noise not noticed at highway speeds.
The power steering pump is probably in need of replacement at this point with this mileage. It does drip slightly, but not a lot. It may be the original pump for all I know. Same with the water pump.
The alternator was replaced last year with a Bosch unit. I have never replaced the O2 sensors. Stock exhaust. Spark plugs were replaced a while back with Motorcraft platinums.
It is now Sunday night and I went out to listen for the sound, and it is not there anymore, but the service engine light is still on. First things to check with a truck that has 217k miles on it?
Was tempted to bring it to the dealer here, but it seems to be running ok in spite of the light coming on. So I may leave it until I get back home and check it more myself then. Can't do much here since I don't have my tools/service manuals etc with me.
Ford F-150 - 1997-2003 :: 1998 Truck Will Not Start Occasionally And Error Codes
I have been having odd problems with my truck for several weeks now and what the problem may be. Occasionally the truck will not start. This happens after it has been run for an errand or to church. The truck turns over but no ignition. Sometimes if I pump the gas pedal very quickly I can get it to start. Other times I have to sit and wait about 5 minutes. I have gotten the following two error codes - P1506=Cylinder Head Temp Sensor and P1299=Idle Air Control Overspeed Error. For two days the "check engine" light was on, but now it has gone out. I have searched for an answer to this problem on these boards and one possibility may be a vacuum leak. Is this the most likely? 1998 Triton 4.6 ....

The Service Engine Soon light has come on on my 2000 F-150 with a 4.6L when I was driving home in the rain. It has about 120,000 miles on it now. What are some of the main reasons why this comes on? Oxygen Sensors?

I have a 1999 F-150 w/ 4.2 V6. and auto trans, truck has 219,000 miles on chassis but only 25,000 on engine and 10,000 on trans. I've been getting obd codes p0705 and p0715. I replaced the position sensor on outside of trans. but I continue to get the codes off and on again. I noticed that the O/D "OFF" light on the shift selector blinks simultaneously when the "service engine soon" light comes on. I've noticed that there is no low gear unless I have it in D from a dead stop, and not even when downshifting manually.

View 4 RepliesFord F-150 - 1997-2003 :: Engine Service Light - Codes P0171 And P0174
2001 F150 5.4L Triton Motor. Everything seemed o.k. then got the Engine Service Light. Checked with reader and above codes only appeared. Read numerous articles/videos and pulled the PCV hose/boot assembly and replaced the whole thing with oem part. Visually checked for disconnected tubing = none found. After this and with the new hose assembly in place I performed a reset. With the scanner still connected restarted engine and read values: ST FTRM1&2 = -.08~+2.3, both oxygen sensor voltages are varying and the LT FTRM1&2 hang around +26 and +28.
From what I understand the ST seems o.k. but the long term is WAY OUT OF WHACK. Started it up again and took carb cleaner spray and covered all the connections I could see = no change in engine rpm. No cracks in the air cleaner body. Big plug to the MAF was inserted and plugging the hole. I am thinking of making a smoke "machine" and trying that or removing the hoses from the throttle body and plugging the holes in the throttle body and see if that clears them up. IF it does then connect one by one and keep checking the values. Lot more work but I am at a loss.
Ford F-150 - 1997-2003 :: Service Engine Light Came On - EGR Replacement Code P0402
Last week my service engine light came on. Friend checked it with his code reader. Got a P0402 code insufficient flow EGR valve. I have read several different threads on this subject on another Ford truck forum, slightly confusing me. Should I trust the code and just replace the EGR valve or do a number of other things that
1. Clean the throttle body first?
2. Test the EGR valve by blanking it off?
3. Test the DPFE valve?
4. Replace the DPFE valve instead of the ERG valve since the EGR valve rarely goes bad?
5. Only get OEM parts since after market parts do not last?

So about 3-4 times per day, my truck will accelerate very quickly with the slightest touch of the gas pedal, then followed by the service engine soon light...I checked for any codes to see what I may need to fix, but no codes are found.
What this could be? I am also having issues to where I a few times per day I have to put my truck in neutral to get it to start instead of in park...could the two be related?

My trucks symptoms include a illuminated service engine soon light, sometimes a high rpm idle, and sometimes a rough erratic idle. When a scan was done it indicated the oxygen sensor was defective. The issue is: which specific one (there are multiple oxygen sensors) or how could I check or determine the faulty one for sure. I am trying to economize and replace only the bad one myself if possible. I own a good multimeter, can it determine the bad one? 1999 F-150 4.2 Litre V6 oxygen sensor dillemna....

I have a new to me 98 F250LD with the 4.6/4R70W. I have maintained this truck fro my FIL as best as I could get him to spend (neglected). Filter and fluid replace with Mercon VI last year due to 2-3 shift slip.
He gave me the truck after it would not climb a hill, just hit stall speed and would not move up a steep hill, as I understand it. I put Seafoam trans tune in hoping it would free up sticky solenoids or valves in the VB.
I finally got it registered in my name and drove it to work and back today. After about 25 miles highway driving it shudders pretty bad trying to climb a hill at low speed.
It seems to me that at this low speed, torque converter lockup should not even be a possibility. I do not have COP, but rather a single coil pack. I replaced the wires and plugs for Dad a few years ago, but some shady shop later told him that I didn't replace the left rear (to make an upsale I suppose). Not sure what they may have done in there.
I have scanned with my ELM 327 and Droid using Torque Pro, and the only Fault is EGR flow.
Ford Super Duty (1999-2016) :: 2003 F250 - Service Engine Light Keeps Popping On And Putting Out Code P0401
I just bought a 2003 F250 from a used dealer. Unfortunately the service engine light keeps popping on and putting out the code P0401, I have replaced the EGR, cleaned the inside, and cleared the code. However it continues to keep popping up and then it will turn off after a couple of days. I mostly drive in the city and the code generally only pops on when I drive on the highway. I have also noticed a lack or delay of power, when I really hit it hard, I think its because the computer is keeping the egr valve open. What it could be?

I have 2003 f250 7.3 automatic 181,000 miles completely stock. Never had chip,tuner or anything on it. I am second owner and got it when it had 70,000 miles on it. Ok here we go I live on top of a mountain and soon as i start up the mountain or any steep hill, or pull or tow something my service engine light pops on. First time it came on I took it to diesel shop they hooked it up to scanner and said it was code p1211 said icp sensor was bad so they put new one on. Couple days later light started popping back on so i decided to order a auto ingenuity after doing some research.
Hooked up to truck started up mountain while scanning at wot light pops on code p1211 and think it was live data I remember seeing icp pressure at 1922 and duty cycle at 63% i was trying to drive and read it at same time and my lap top went dead. What does this reading mean 1922 pressure/ at 63% cycle done little research but dont really understand. Year and half ago replaced all orings on all injectors, new rebuilt hpop pump. New ipr valve, glow plugs, past month 2 different icp sensor new,and new ipr valve new pig tails on both and light still popping on.
