How to fix P0237 Sensor A error?
I have already tried changing the MAP sensor...no good. I understand that it can be a short to ground, but where in the heck is the wire starting at, and where does it end up....maybe I can cut and run a new wire? I'm trying to ask how to troubleshoot this code and elliminate it. My truck has been showing the SES light for 6 months now with this code, at first it would co9me and go, then shortly there after it was on for good. I have removed all my Banks programming (Big-Hoss and 6-Gun) and cycled the key 6 times, removed the battery terminals for 30 min...and start her up only to find that its not related to the Banks stuff. It has to be a chafed wire some place. Please help!
