How to Read SES Light on 93 corsica 3.1

11-13-2009, 02:45 PM
I done some research but to no prevail, called all my local parts stores and they say they cant read anything older than a 95. I have read them on the corsicas before but has been a couple years anyone have any advice on readin the SES light? i just dont wanna stick the jumper wire in the wrong slots.

Thank you

The 93 is an OBDI type system, and auto places anymore won't checl for these, which is stupid considering the tool needed is cheap...that being said..I have always used a OBDI scan tool on mine but here is a shortcut to a site for corsicas and it is explained there. Sorry, I can't find a pic of the pins right this second, and I no longer have my manuals. if I find more I will post back. But this should do you.

You most likely know this already but 15 is coolant temp sensor and 33 is MAF sensor. The MAF can get dirty, must be careful if cleaning it or can cost some money. If you have not done anything suggest a book , GM service manual before getting started.
