88Regal Limited Posted December 28, 2008 Report Posted December 28, 2008 Have 3 codes and trying to find out what they are. Used the list in the FAQ but it didn't have them. 13: Oxygen sensor voltage stays between 0.35 and 0.55 volts for 60 seconds when the TPS signal was above 4%. The engine had been running for at least 2 minutes. 35- I believe this is high idle, looked it up before (?) 42- ??? Quote
4door Intl Posted December 28, 2008 Report Posted December 28, 2008 While this list isn't complete, it offers likely reasons for each code below it: http://www.seanster.com/scantool/ecm-codes.html Quote
88Regal Limited Posted December 30, 2008 Author Report Posted December 30, 2008 thank you so muc!. I was right about the 35, and 42 is "Poor routing of EST harness and/or poor quality ignition wires (EMI induced electrical noise).... I think that's the culprit. I notice when the car is running the CB picks up a slight hum and buzz along with the radio, and the wires have probably 100k on them. Thanks! Quote
