P0344 CMP Sensor Circuit Intermittent
P0340 CMP Sensor Circuit Malfunction
I don't have the other codes listed in my service manual, but I'm starting to see a pattern here. Where did you get your CPS? I've heard of ones from the auto parts stores going bad as soon as there put in.

 

had had a spare cps and then ckecked it again through a friends truck and it worked fine still down any help would be appreciatded thanks jtm

 

fuel pump and fuel filters?

 

Check the wiring to the cps. I had a similar problem that ended up being bare wires at the cps plug. Also, make sure the connection is clean and use some dielectric grease.

 

same problem with my 2002 f-250 diesel. dtc codes p0008, p1aee, and p08a6. any luck with your truck? i have changed throttle position sensor, cleared problem for abuot 3 weeks then problem reappeared. any help or other info greatly appreciated.
