Anybody know how to read the Codes ?

My check engine light came on a couple times over the past month or two. It happened when I really opened her up and went off a few minutes later. Now the check engine light is on all the time. Car runs great, fuel mileage is fine. The light just stays on. How do I read the codes ? Any ideas what it might be ? Also on another matter. Do 2.0 's normally sound like they have a slight knock around 3 to 5000 rpm's ? I really don't think it's the rods. The sound kind of scares me a little bit though.

You have to have a logger or an ODB II Scan tool to read the codes.

Not actually. A '92 is an non-OBD II car. You can read the codes with a analog multimeter or a simple piezo buzzer you can buy at Radio Shack. I forget the exact pins on the diag connector (I think pin 1 and 12 with 12 being ground) then you count the pulses to get the code. I have a LED (with resister) installed in the dash that's connected to the diag port all the time.

I thought it was something like that. Can you check the pins and get back to me ?

 

[steve]

Your going to need the codes too. Here's a Diagnostic Port Code FAQ. If you use a piezo buzzer you don't need a resister.

What a great resource, evryone should check out that main website. BTW if my lifters are causing the phantom knock, what can I do to eliminate it ? Also, do you have to remove the tranny to replace the sychronizers ?

 

[steve]

You can clean the lifters but the problem will come back. Replacing them with the latest version seems to solve the problem but then it's too soon to be sure.
I think the tranny has to come all the way apart to replace the synchros.

There is rebuild information on the VFAQ Site under drivetrain. You should have the VFAQ's bookmarked.

also i believe the codes are in the vfaq in the 1000 questions area
