Thread: p0202 code help

Can anyone tell me how to check the injector wire for a short from injector to pcm. Got the code and swapped for a new pcm and got the code with the new one as well. This happened before and had another pcm shipped to me and went away for 4months.I then put the original pcm that gave me the code and now i dont have it. I am thinking its a wire issueThaks. o and when it first happened i put a new injector in and still had the code. so i dont think the injector is bad. Thanks for the help everyone.

So no one chimed in yet let me give more detail. A while back I got p0202(injector stuck open) did the first obvious solution swap injectors it wasnt the injector. So got a new pcm and it went away for a while 4 months then i got the code again. I assumed it was the pcm again and got another pcm. Replaced the pcm with the new again got the code right away put the original that got the code the first time and ran fine for a few miles and didnt get he code. Put the 2nd pcm that got the code that replaced the first the pcm that got the code and it ran fine for half a day then got the code . Any ideas

check harness for damage, possibly rubbed through to ground
