I'm not sure the codes for a 92 are the same as codes on an 87 (earlier C4s) Although I know the H stands for a History code. Posted a web site-unfortunately it's no there any longer.

I'm sure others will chime in. Good luck

The problem with a translation, is that it only tells you where the erroneous reading came from, not the cause. Don't shoot the messenger. Just because an out of parameter reading comes in to the ECM, doesn't mean that the sensor that sent it is bad, and sent bad info. It is very likely that the info is correct and that another fault, somewhere, caused the reported condition to exist. The factory service manual will translate the codes and give you a trouble shooting procedure for each code, to help you track down the cause of the problem, without replacing good parts (throwing money at it).

RACE ON!!!
