Ford F-Series Computer Problems



  • P0340 Camshaft Position Sensor circuit fault . There is no po-344 code. Now, this may make you feel a little bad... "and I am yelling"... "DID YOU REPLACE THE STUPID SENSOR"???????????? This is bad, this is why your engine is cutting out and this is why your "check engine light is on"... if you don't know how, take it in to the garage and tell them to replace the sensor. Now, that wasn't hard was it. It's causing your computer chip to act up, which is causing your truck to miss. Doesn't matter if it's in intermittent or not.. it "needs to be replaced".
  • Go in to Ford, not the same one that wants $1,500 for the tranie.. have them hook it up to the diagnostic machine. That should give you some error codes that can tell you what might be causing it. If you don't want to go to Ford, take it to Auto Zone.. NOT discount auto..Auto Zone. If you have codes and you don't know what they mean, give me a hollar at my regular email addy. They might not let me post it, so you know the sign for @ and so write to me once you have had it diagnosed.. with code numbers. emtdawn "at" and let me know the numbers of the codes.

  • I have a 2006 F150, aftermarket remote start. I pushed the remote start today, it started, made a horrible metallic sound, like something broke, which I assumed was the starter. I changed the starter, which was acting up slightly for a few months prior, still won't start. I checked all fuses, they are all ok. I hear the fuel injectors engaging, all the lights work fine. I had an issue with the remote start and the PAS system a few months ago, and learned how to disconnect the remote start. I did that, still won't start, and my arming system is fine, meaning that the vehicle is not armed while I am trying to start. I wonder if the sound I heard was the flywheel teeth breaking?? I looked at the old starter and there are 6 teeth with excessive wear, like a stripped screw. The rest seem decent. Any ideas??? The truck has about 46K miles and my husband is pissed. PISSED. I was a mechanic for several years, and this one has me stuck. I've changed a hundred starters and never had this problem. The new starter bench tested at Oreilly's ok.. but, maybe I'll try checking it myself.. HELP!!!!!!!!!!!!!!!
  • By the way, today the inside unlock buttons will not unlock the doors. I have to manually open the pass. door from the inside. Rechecked starter, and it is good.. Totally lost here.
  • Well.. In the light of day :) I found a fusible link (aka-a bigger fuse in the fuse box for the normal person) that had blown. I didn't see it in the dark, but went today and re-checked every fuse. Problem solved!
  • My 2001 F150 is doing exactly the same thing. Did you ever find out what the problem was?
  • yes .. it turns out the ignition is somehow wired into the door panel with the window and door lock controls .. we popped the door panel off and some wires were kind of loose .. pushed them back in and it has started fine ever since
  • could be your cam sensor. I had replaced mine when the engine stopped on me. according to your millage you have, it might be covered under warranty. call the dealer first.
  • My ford F-350 diesel truck will not release the 4 wheel drive what can I do to release it?
  • has anybody switched thier v10 over to e 85 and if how did it go
  • what causes the Codes P0470 and the P0299?
    I do know the P0470 is Exhaust back pressure and the P0299 is turbo underboost. I just want to know what causes this and how to fix.
  • I can tell you exactly whats wrong...This has been a common occurance with ford f-series for years...don't know why they haven't owned up to it. The problem is with the GEM (generic electronic module) and it screws down to the back side of the interior fuse panel. This circuit board controls the functions of the things you mentioned plus the auto power window circuit and the heater fan motor, and gauges. The problem is not really the GEM proper, which is a good thing because that circuit board retails for well over $600., but it is due to water entering the cab during rain storms through the cowling and dripping on the GEM case and the top of the fuse box. The water actually enters the fuse box where it shorts the connections that the GEM is plugged into. I just finished a repair on mine for the same thing without replacing the GEM and it's working great. I took pictures and wrote a little narrative on how to fix it. If you're interested, email me at and put in the subject heading GEM, and I'll email you the directions. It takes only a few tools and probably a couple of hours to get it back on the road.
  • when driveing my engine jumps like i am pushing the pedal up and down and cruise control stopped working same time please help going nuts

    I am having a problem with my 2007 F150, 5.4. It has 33,000 miles. Recently when it sits unused for 3-4 days, I have an issue when first starting up. The tach and fuel gauge vibrate and take a few seconds to fire up. A clicking sound accompanies the shaking. The message center then indicates a "Tire pressure monitor failure" and the low tire pressure indicator comes on. All resets typically when the truck is shut off and restarted.
    Any recommendations would be appreciated.
  • Question for you ford techs

    I had a reading that my FICM was only at half of the voltage so I repleaced the FICM with a new one that came already programed, they told me that all I had to do was take out the old one and put the new one in and it would run. Here lies the problem after installing the new one when I go and start the truck it just makes a clicking noise and the starter does not engage. Do you think by installing the new FICM that computer now needs to get flashed? I had the truck running before I installed the new FICM but it was rough at first, I replaced the FICM the same day that I had it running with the old FICM installed. I even went as far back to installing the old FICM because the truck ran, when I installed the old one the truck did the same thing just clicked and the starter would not engage. So I am thinking that I might need to take the truck into a Ford Dealership and have the computer reflashed?

    Please give me your thoughts

    My 99 F-350 powerstroke ittermittantly runs rough then you can kill it & start up again & it runs smooth. I have added 4" exhaust, S&B cold air filter & ez chip from Edge Products. Did fine until 3 days ago then suffered power loss without towing. Had computer cleared and am running with chip turned off. With chip on & towing or heavy accerelation service engine light would go on & off, which Edge says is is normal with 7.3. 3 days ago service engine light started coming on almost all the time running without towing. Anybody know anything about this? HELP......
