Ford F-150 - 1997-2003 :: Check Engine Light Is On - Cylinder Head Over Temperature / Overheating
I have a problem nobody can figure out. My check engine light is on. Took it to Advance to have it scanned; came backwith Code 1226, Brake warning light ground short ( not concerned that at this time); Code P1285, cylinder head over temperature; and P1299, engine overheating (this repeated 4 times).
Now for the symptoms: Truck start and runs good, except with engine light on, runs about 4 miles, then the temperature gauge goes all way up, oil light come on (But oil pressure gauge is OK), Have loss power, and heater has no heat. I shut key off, restart, runs perfect, gauges OK, heater OK.
Ford F-150 - 1997-2003 :: P0306 And P0174 Codes - Engine Overheating And Coolant Reservoir Dry
I have a 1999 4x2 F150 XL, 4.2L engine, 5-speed trans., about 197,600 miles and have been getting P0306 and P0174 codes. The check engine light came on and stayed on. Also, pretty much randomly, my engine over-heats and the engine compartment coolant reservoir is suddenly dry as a bone. I bought the truck new and this has only happened twice, during normal driving.
Clearing the 0306 and 0174 codes. Not sure what to do about the over-heating thing.. What I've done so far to try to clear the codes is the least expensive stuff:
=> Replaced both forward O2 sensors, have read where the two rear O2 sensors don't necessarily need to be replaced so I haven't replaced them yet. The sensors that came off are Bosch, as are the ones that I bought from Autozone and installed.
=> Replaced old spark plugs with Motorcraft brand, gapped to 0.054 in.
=> Replaced old spark plug wires with Motorcraft spark plug wires.
=> Cleaned the MAF sensor
=> Replaced PCV valve and replaced an section of elbow hose near it. The original elbow had a big hole right at the 90-degree bend, on the inside.
=> Replaced a cracked, dried-out, vacuum hose coming from the evap cannister purge valve and going to the front underside of the upper intake manifold.
=> replaced fuel filter.
After doing all this, I took it out on the road long enough for the computer to wake up and relearn and got the check-engine light again. Only this time it was flashing. I gather from reading in this forum that a flashing CEL is worse than a constant-on CEL so I drove back home and have yet to take it back out.
After reading about problematic ignition coils, I followed a procedure in my Haynes manual to check mine out:
=> Verified the correct resistance values at the electrical connector (0.7 ohms),
=> Verified battery voltage is present at the harness side of the electrical connector (about 12.6 volts),
=> checked the resistance values between the three sets of 'towers'. Starting from front to back, the resistance readings were 13.06 kOhms, 13.12 kOhms, and 12.98 kOhms. The correct range in the Haynes book is 6.5 to 11.5 kOhms so I thought maybe my ignition coil was bad.
I located a Motorcraft ignition coil at a local O'Reilly Auto Parts store, went there, and was able to check the resistance values on that new one. Turns out the resistance on the new one at the parts store is pretty much the same as that on the one on my truck (all three coils were 13.something kOhms), so I haven't replaced the ignition coil. I guess either my Haynes book is probably incorrect or the ignition coil on my particular F150 has different resistance values than the rest of the vehicles covered by that manual.
Next things I'm looking at replacing:
=> egr valve and the associated line to the DPFE sensor. (DPFE replaced a few years back, as a result of a P0401 code)
=> iac valve
=> upper intake plenum gaskets
I'm kind of at a loss at this point. I hate to just continue replacing things without knowing that I'm replacing the right things.

I have a 2000 - F150xlt - 4.2L - V6:
Today while leaving work for lunch I started the engine and suddenly the ABS light came on and the engine cut out before I put it in gear. Then as I was driving each time it cut out the ABS light came on. So I stopped at the convenience store across the street from work to get some gas thinking it was low although it had a 1/4 tank. But after filling up it would not start. Then relay #2 began clicking in the fuse panel and would not stop whether the key was on or off. Several minutes of this went on and then I pressed the brake peddle in once more and everything on the dash lighted up, the dials fluttered around, the clock came back on, etc...
So I tried starting the engine again and suddenly everything started working and the engine started up. I drove it home and it ran fine with no issues, no cutting out or anything. After lunch I tried it again to head back to work and the truck would not start again. But this time there was no clicking from relay #2. Everything was dead until I pumped the brake peddle several times with the key off and then turned key in the ignition and then it started right up and drove like normal. Why it's doing this and what to check to fix it?
Ford F-150 - 1997-2003 :: 2000 5.4L - Intermittent Engine Knocking Underneath
The knocking started very suddenly 2 days ago - but not after any unusual events, other work etc. Truck has 145 K, and otherwise starts & runs perfectly. Doesn't use oil.
I heard it from in the cab, windows closed. At first, thought it may be a rod bearing - but if so, not terribly loud. Didn't drive it any more after getting home. But starting it in the drive, the knocking was audible.
Then I discovered it * completely disappeared * several times, after shutting off engine, then restart a few seconds later. When that happens, absolutely no knocking at idle or reeving it up a bit. But it may return on the next 1 or 2 restarts, then disappear again.
Since the knocking * completely stopped * on some restarts, does that rule out a bad rod or main bearing?
I haven't seen oil gauge pressure fluctuation, whether it's knocking or not. The gauge is where it's always been - well above 1/2 way. But, the gauge also doesn't move when I rev it to around 2000 RPM (? may be normal not to move, after engine's already running?). When the knocking is happening, increasing RPMs also increases the knocking frequency.
Can't hear the knocking from top side of engine w/ hood open - even using rubber hose to my ear & moving it around. But (when) it knocks, can easily hear it inside the cab or under the truck.
From underneath, knocking is more in the center of truck, near the back of block / oil pan or tranny bell housing. I can't isolate the noise as more on one side of the block than the other.
Could the oil pump itself be making a knocking noise? The knocking is "similar to" a rod knocking, but doesn't seem quite as "hammer on metal" metallic.
There are no DTCs showing on my scanner. Only odd thing was, for "O2 Monitor Test," it showed "vehicle did not return data for any O2 monitor test." Though under the scanner "I/M Monitors," it shows O2 Sens Mon. "OK," and O2 Sens Htr "OK."

We have a 2002 F-150 4.6L 4x4. The engine went bad and we bought a new engine (remanned ATK). Had this engine installed and a year later it was bad and was determined it was a manufacturer defect so they sent a replacement engine under warranty.
We had this new engine installed. The mechanic fired it up and it backfired through the intake. They claim that the compression is good, the fuel pressure is good, and the timing is correct. Can they check these things when the truck is not running? The mechanic is completely frustrated with the situation...
Everything I read leads to a timing issue but they say they checked it so before I go in there screaming I want to make sure it couldn't possibly be anything else...
Ford F-150 - 1997-2003 :: Swapped 2001 5.4 To Replace 4.6 - No Start
We have a 1997 f150 with the 4.6 in it originally. The 4.6 was pulled and a 2001 5.4 engine was swapped. I was called to see why it could not run. I did some preliminary tests and suspected the PATS system.
I cannot get the fuel pump to run by jumping the relay and I am assuming all the wiring is proper from the swap.
The 2001 5.4 engine ecu has been transferred over. I run the obd tests and get a bunch of codes but none point to the pats system. The theft light does not prove out or does not flash. I can get it to turn on via my obd scan tool. I have an elm tool.
I do know the 1997 cluster was not changed. The ignition from the 2001 was swapped and have only 1 matching key with it.
When I jumped the fuel pump relay, I produced the code p0232 which tells me the computer saw current in the pump circuit when the PCM has it disabled. Should a swap of this kind also include the pats components ? I also cannot get the fuel pump to run by jumping the relay.
I have the codes :
P01703
P0232
P01747
P0750
P0755
p1451
P1409
P1633
Ford F-150 - 1997-2003 :: Replace Blend Door Actuator?
Whenever my A/C is turned on, it blows nice cold air. As long as the blower is on "1", "2", and sometimes ", it blows cold air. If I turn it to "4" I can hear a small "thud" behind the dash. It sounds like the blend door is shutting. All my functions work like they should. I think the actuator is goin out and isn't pushing the door all the way closed, and when I turn it to "4" it pushes it te other way.

I have a 2000 f150 4x2 5.4 168k... Check engine came on,started shaking, weather was really cold. RPM would be a little high then low then back up. Especially when I turned on heater. Felt like truck would die but never does nor does it have issue starting.
So far, I have replaced two oxygen sensors inside engine,all coils, spark plugs, fuel filter, had injectors cleaned, intake cleaned. Truck runs better but, light came on a day later again. I can feel the tiniest of shaking going on and, cold mornings still make RPMS a little unstable. I was driving truck on highway at about 60 mph when a slight tug was felt and Truck check engine came on. I feel truck heavy, once it warms up completely, a little lighter.
Codes came up at auto zone as P1151
But I'm running out of options and frankly, money to fix this truck.
Checked the MAF and looked okay.
I'm with minimal skills.
Ford F-150 - 1997-2003 :: Engine Seemed To Slip Into Neutral When Speed Increased And RPMs At 2000
I am having issues with my 2003 F150 4.6L truck. It just happened today when driving home. It started fine and then when I increased the speed and the rpms went up to about 2000rpms, the engine seemed to slip into neutral. I stepped on the gas but the truck would not accelerate, it was just coasting. I pulled over to the side of the road and came to a stop, but didn't shut off the engine.
After a few seconds, I proceeded to give it some gas, and it engaged in gear and accelerated...until I got to about 25mph & rpms increased to about 2000 again. It did the same exact thing....seemed to shift back to neutral so that I could not accelerate. I had to keep pulling over to come to a stop, and then slowly proceed again. I wasn't too far from home & I made it. What this issue could be?
Ford F-150 - 1997-2003 :: 2000 V8 Running Rough At Idle And Check Engine Light On
I started out with my 2000 F150 with a 5.4 V8 running rough at idle. It would idle way down slow and then rev up a little over and over. On a couple of occasions it would even die when in drive or reverse. I did finally get a Check Engine light so i put it on my diagnostic program to see what was up. Here is what I got:
P1151 Lack of HO2S21 Indicates Lean
P0171 System Too Lean Bank 1
p0174 System Too Lean Bank 2
After doing some reading up I checked all my vacuum hoses and cleaned my mass air flow sensor. I then got the same codes again after a few minutes of running. So I went to the next thing that was recommended, the upstream bank 2 O2 sensor. After changing it the truck ran fine for a couple of days, no issues. Then all of the sudden it idled a little funny again and I got a Check Engine Light again. This time:
P0171 Bank 1 Lean
P0174 Bank 2 Lean
P0300 Random/Multiple Misfire
I reset the light to see if I would get the same again later. Before the light came on again I filled my truck up with gas and it seemed to be running pretty good again. Then a day or so later it set the light again. This time:
P0171 Bank 1 Lean
P0174 Bank 2 Lean
P0136 O2 Circuit Malfunction Bank 1 Sensor 2
P0156 O2 Circuit Malfunction Bank 2 Sensor 2
P1131 Lack of Switches HO2S11 Lean
P1151 Lack of Switches HO2S21 Lean
I went ahead and drove for a few days as it had gotten really cold here and I didn't feel like messing around in my shop since it isn't heated. A couple days ago I needed gas so i filled up again. Suddenly the problem was gone again. Truck ran fine idled fine no missing or odd idling at all. That lasted a day or two before it started acting a little weird again. At that point i was down about 1/8 of a tank from full. I have read that there can be issues with the fuel pump.. I am kind of wondering if that may be it now. But I haven't had to deal with this sort of issue before so I am unsure what to check next. The truck always runs fine off idle, it only seems to have the issue when it is idling. I had reset the codes the last time and i have the light on again now. I haven't checked it yet but I am sure it is going be some combination of what i have had in the past.
I have read that the IAC valve can be an issue as well. I had a problem with mine sticking a couple years ago and when it would do it you could just tap it with a wrench and it would idle up. But it never died like it does now and it would also idle a lot slower than it does. Back then I cleaned the valve and had no more issues with it. The truck has always had times when it would act weird at idle usually after slowing down after being at highway speed. The current issue happens at all temps cold or hot.
Ford F-150 - 1997-2003 :: 2001 - A/C Overheating Within Minutes?
'01 F150 XLT 5.4L EFI 207,000 miles
I've had this truck since '03 @ 45,000 mi and have loved it ever since. It hasn't failed me yet, until now. Living in TX with no A/C is the pits,
He first replaced the large hose assembly (with a non Motorcraft part) due to a pinhole then recharged the system. It cooled great until the pressure pop off valve (or whatever it's called) blew all the freon out.
His first suspicion was the fan clutch, which was replaced with a motorcraft fan clutch. Next he used his a/c machine to evacuate/flush/recharge the system - problem persisted. Lastly, he cleaned the radiator and condenser fins and recharged again. The system still overheated and lost the freon.
While the freon is in the system it cools like never before but after driving it, parking for a while, then re-starting it overheats within minutes.
