Car Forum / GMC Cars / June 2006'95 AUAROA Ghost Codes?
after One Backfire then 14 Miles limping home, the local Mobil Station ran a diagnostic Stating the Following: 34 MAP SENSOR 43 LEFT O² SENSOR 36 EGR PINTEL RANGE 45 RIGHT O² SENSOR 15 INPUT SPEED SENSOR 52 DEFECTIVE ECM 109 INTERNAL ECM PROBLEM 121 A/C TEMP SENSOR PROBLEM I love the car. It ran very well for 8K Mles, over the the 2 years I dove it,... before that Dang Backfire! ANY helpful feedback much appreciated! --- BOB, PLUMB Hi. First off, I would say the odds that a whole bunch of sensors went bad at once is unlikely. Just my gut but I might suspect the ECM is bad, or you have some serious electrical problems. I don't know if there is an easy way to check and ECM but try. Also check all grounds and appropriate connectors etc. >after One Backfire then 14 Miles limping home, >the local Mobil Station ran a diagnostic Stating the Following: [quoted text clipped - 16 lines] > > --- BOB, PLUMB maybe the headlight fluid is low.. :) no.. sounds like the ecm.. if it backfired, it probably did it because the computer took a dive and sent bad codes causing the backfie in the first place. > Hi.
