Ok thanks for all your help. Can I look him up by his name or will u b able to let him know about the problem?

Go to the bottom of the main page, he'* listed there. He'* also under forum leaders.

Ok thank you again for your help.

Quad driver module is part of of the PCM. Gonna have to wait for Boosty to come in and help out on this one.

Why Mike??? I no longer have the 95 FSM (that I sent to you) and therefore can't be anywhere near as much of a help as the guy (you) that I sent the FSM to.

Time to crack the book buddy. Let'* get some of that good info listed out. Dan.. meanwhile, searching out the fixes on those other codes and even QDM 2 will be the biggest help for the OP.

You guys don't "need" me for help on this one.. I'd be looking at the FSM (which I don't have anymore) and searching the forum (which we can all do).

Bill, is it possible for the 1995 OBD1.5 system be just the same as the 1992 OBD1 system?

A majority of the stuff is the same. I'd use the 95 fsm as a general guide. Call it a Chiltons and take some of the info in stride where it doesn't seem to fit perfectly.

I don't have a 95 FSM, I start at 97 and go threw 2005. As I said, he needs to check the 3 listed sensors and wires. Although, to have all 3 fail makes me wonder if there'* a grounded wire.

Dan.. it'* the way that pcm works. If you haven't dealt with an issue on one of the pre 96'* then its tough to understand the way GM set those things up.

And... "he" chose a SN of "SpecialWoman30".. not sure we are working with a man on this one.

A quad driver is a circuit that is built into the pcm. It controls 3-4 different engine items and when one goes bad, the code sets. Then it'* up to diagnosing to determine which of the 3-4 is actually a bad item.

2 of the codes point to the cam sensor. I say start there.
