Truck stalled got these codes... Restart and drives for short trip but now only getting P2105 and U0300.... Is PCM bad????

 

 

What kind of work was recently done on this truck ?

 

No work has been done.... Truck ran great till one day stalled and got P0600 P2105 and U0300.... I clear codes and now only getting P2105 and U0300... I just wonder if PCM is bad..

 

PCMs don't just lose programming , before going that route, suggest you have a good,qualified shop check to verify the throttle body and related sensors are working.

If they check out and connections are assured, then the only thing left is the PCM.

 

I did wiggle test while running can't get to stall.. Checked wiring and looks good.. At idle it will run I can put up RPM ( open throttle) seems more like under load driving... Its like a switch (shut off) what kind of bothers me is is that P0600 that was there but not after I erased... And I was told that's A PCM..
Its first time posting on here.. And thank you for ur time... I'm just puzzled throttle body PCM..

 

Tried wiggle test again.... Took connector plugs apart no corrosion no bent no tabs out... idles great revs.. Stalls out during drive..

 

Can you get this to happen if you have your foot on the brake, trans in drive, and raise the engine speed a little ?
Sometimes when the engine moves as when driving due to a worn motor mount a connection opens and power is interrupted and the engine stalls ?

 

Yes I can!!! I get rpm up around 2200 foot on brake in drive and U can fell it start to like misfire then shut down... But no misfire code and no p0600 code

 

It comes back with p2105 u0300 and p1000 but that p1000 code as far as I can remember is always there..
