Ok. so here's what happened to me. I am on my way to Kellogg, ID from Salem Oregon. Bout half way there, I stop for a moment, then restart engine and get a "check engine lite". So as I am on a tight schedule, I say "Oh ****" among other things. Being only mildily "BOMBED" I hurry into a parking lot, pull my EZ, get on the CB and look for a dealer. I go to the dealer, and guess what the code is? P0071 (Ambient Battery Temp Sensor Performance). Lesson learned? Is there a chart of codes and how do you get the code # displayed? Waisted a lot of time for nothing, and obviously didn't have to remove the EZ as the hood was never even raised. Obviously, I have shot my warranty in the ASS by just merely having a PacBrake so why should I care if the EZ is in place if I have to go to dealer. Any thoughts, comments, etc. would be appreciated.
