I know this subject has probably been posted before, but here it goes:
I have not been experiencing any engine problems until yesterday. Driving on the highway at about 65 mph, the truck violently shook, loss power, blew one puff of gray smoke and I pulled over. The engine was still running and sounded normal after pulling off. I then drove to my destination (about 10 miles) with no problems.
However, about a mile after leaving, the engine just shut off. There was no smoke or shaking, just shut off. Let it sit for a few minutes and it started right up and sounded normal. Pulled off and everything seemed fine, but after about 100 yards, it simply just off again. I repeated this process one more time with the exact same result, then had it towed to Ford.
They haven't looked at it yet (weekend) so no feedback from the service dept. yet. Any ideas or possible causes, solutions??? I filled up on Monday and burned half of the tank so I doubt if its bad fuel, no water light either. I'm just glad its under warranty still. Thanks for reading!
Cam position sensor (CPS or CAMP) failure. If it is under warranty, have Ford fix it and if not get a new one from International (much less money for the same part) and install it yourself.
really appreciate your feedback. Is this a common problem with these trucks? Mine is under warranty still. I'll probably keep an extra one in the truck from now on. Thanks for the tip on buying it at International! Take care. I'm am still waiting to hear from Ford on what they think it is.
According to the 2 places where I have had the sensor replaced 3 times, it is very common with the later model trucks. My 2002 has been towed 3 times for the same fault, with the same symptoms you described, and had 4 cam sensors in as many months (original and 3 others). For this reason, I rely entirely on my '96, which has never had any problem like that. Hopefully it will not start. I bought the '02 to take some of the mileage in my work off the '96 but it did not work out that way.
The tow truck driver did say that he tows the 01' through 03' trucks "all the time" for the same symptoms. He mentioned it was "some kind of module or sensor or something like that."
Cookie88, are there any special tools required for this repair? Are there any tools that would make this "roadside repair" easier/quicker? Any tips?
Thanks Johnsdiesel for the clarification on the letters. Will help when I pick up the spare!
Needless to say my confidence in the truck has been shaken a little bit. Hate to be stranded with the family far from home. We travel quite a bit, so a spare CMP makes sense. Hopefully, none of us will experience it again. Take care.
Mike:
It is a piece of cake. It takes a 10 mm wrench. There is one bolt holding it to the front cover (the part that has the timing indicator attached to it) and you'll need a pair of pliars or a screw driver to pry it out of the hole, then put a little oil from the dip stick on the O-ring of the new one, push it into the hole until it seats against the front cover and put the bolt back in. Don't over tighten the bolt.
Thanks for the specifics on the sensor change. Sounds like you definitely have changed one or more before. I'll make sure I have that wrench size available in the truck with the spare sensor.
I picked up the truck today from Ford and indeed, it was the camshaft position sensor (CMP). I noticed on the service invoice it says "clear codes and road test." If I repair this myself, do I need to clear the codes or have Ford do it before it runs correctly? Can I clear the codes myself? Thanks again.
Most times there won't be any codes for a simple cam position sensor failure. The ECM won't know the difference between CPS failure and turning the key off. That is why it is such a PITA to diagnose. If the failure didn't give you a check engine light, there probably weren't any codes of any significance to clear.
The "check engine" light did not come on, just the "service engine soon" light came on. Never had either light come on before, so I assume they are different lights. I think the service engine soon light is just for emissions related problems?
Well, everybody calls it by a different name -- check engine or service engine soon, it is all the same. If your service engine soon light did come on then the ECM detected a failure that set a code in the computer (not all failures that set codes in the computer will turn on the service engine soon light). If that code was set as a result of the CPS failure, the light would have gone out as soon as you started the engine with the new CPS installed and the code would have become inactive which means it would have still been there but it would not have caused the service engine soon light to come on or caused your truck's computer to run in open loop (limp home mode). If the light comes on while your truck is running, you'll be running in open loop. Probably the reason the tech erased the codes is in case you come back in a day or two with a new problem, he'll have current information to draw from.
I never used a fuel additive until 3 fill-ups ago and the CMP sensor malfunctioned. Any possible link? Just gotta ask. The engine performed a little better with the additive, but if there is some kind of link, then no more additives! Thanks.
