PCM Staying in Open Loop?
Hey all,
No idea why but my PCM indicates that I am in closed loop but all I get is cell 16, 17 & 18 reads. Using Datamaster and TC.
Anyone seen this before and resolved the issue?
BTW, I have set up the fans to be on constantly by bypassing the PCM. I am wondering if this is it. I get a code 77 (fans not working). I can do a bypass if this is it. Yes, you have to do weird things when you do conversions. This is my only code. However, I did bypass the fuel enable also but don't get a code for that. I will ground that one to give it a false signal.
Thanks,
Ben
