new here-how do i check for fault codes

97 pontiac grand am with my engine light on. how do i check for fault codes. is it on-off, on-off,on-off,on-off-on?
thanks

Welcome. Most auto parts stores like Autozone will hook it up to check the codes for you.

thanks man, ill look into that. I was just hoping that there was a way i could do it with out the costs.

your 97' is odb-II,
which means you cant retrive the codes the way the odb-I and pre odb were.

Since you live in Canada, Autozones probly not an option.
I dont know whats available besides, everyones fav, Canadian tire :)
But you will need to get it scanned.

Good Luck
