Pulled some codes and don't really understand them...help
I pulled some codes today and don't really understand what they mean or where to even start looking for the problem. Here they are:
P1139- water in fuel lamp circuit malfunction
P1670- PCM to IDM communication failure???? No idea what this means
P0781- 1-2 shift malfunction? I just had the trans rebuilt 17kmiles ago
P1247- MAP low boost pressure( not sure but pretty sure my ccv didn't get hooked back up last week
I cleared the codes and they haven't come back yet but to prevent it where and how should I start looking?
Re: Pulled some codes and don't really understand them...help
I didn't get 1298 so I guess it might just be a bad connection than? I got some codes for my gp's, iah, and icp which I already knew but none were 1298. My odd concern is the PCM, idm and wif light as well as trans but that didn't come back either once I cleared them? I'm at a loss.
