code reading frenzy

code reading party

I got a bunch of codes today:

KOEO:
335 - PFE or DPFE sensor voltage out of Self-Test range.

CM:
214 - Cylinder Identification (CID) circuit failure
332 - EGR valve opening not detected.

KOER:

326 - PFE or DPFE circuit voltage lower than expected with zero EVR duty cycle.



soooooooo, whats that all mean? Seems like the EGR valve might be sticky. If I cleaned the valve, do you think it would all go away?

for 214 will your truck run?? i'll check the others later

well chances are you have a bad DPFE sensor, that will likely fix code 335, 332, & 326

for 214 you should check your camshaft position sensor I beleive that is what the ECU uses for CID data, although I would expect a CMP error, I'll need to do some reading on that one.

the truck starts and runs great.

although under low to mid throttle, it surges just a tad bit

full throtlle and idle is great. i think thats due to the egr not opening.

going to swap DPFE sensors and see what happens.

you should also check the EGR tube for blockages and all the vacuum lines to the DPFE
