Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi Im David .....and unfortunately this P0601 is pointing to an internal fault in the PCM. The only repair for this code is to replace the PCM. If the PCM was able to be re-programmed, you would also have the P0602 set as well.
yes the pcm would cause everything thats going on. you cannot buy an already programmed pcm as it has to be programmed to your vin.
checking in to see how its going
