a pro repair maual and a good scan tool are needed so you can follow the diagnostic repair tree. a code reader is sometimes a teaser. a no cel means you can drive it but it seems you have other issues....gas,stat,soft codes and other surprises
Hello.
I have read several posts about 1123 and 1125. These are the codes I have. I am not finding a definitive answer if it is made or co2 sensor or the proper way to test.
Any ideas would be greatly appreciated.
Take care
I have taken out the market and cleaned, erased codes and they came back.
