AL Posted September 27, 2009 Report Share Posted September 27, 2009 Code 42 is Electronic Spark Timing Failure... I am not sure what causes this code but when I go to clear it, It comes right back... I was thinking something with the ICM could cause it but I am not sure... I just swapped in the motor and am now getting this code although the car runs and drives fine... I dont like seeing lights on my dash Quote Link to comment Share on other sites More sharing options...

ManicMechanic Posted September 27, 2009 Report Share Posted September 27, 2009 My S10 had a code 42 when I bought it. A new ICM fixed it. Quote Link to comment Share on other sites More sharing options...
