They all quit working at the same time. Its a 92 Si. The engine light comes on after driving for 2 minutes, but i cant read it cause it turns off when im in acc. Any ideas whats wrong?

 

When the CEL turns on, leave the engine running and then jump the service connector to retrieve the code.

It's likely code 17 for the VSS atop the transmission. If so, unplug the 3P VSS connector and check for battery voltage from the power wire (key in ON(II) for this test) and continuity to ground on the black ground wire, and then continuity between the VSS connector and respective pin of the ECU connector and cluster connector. If all is fine, consider replacing the VSS.

 

can i check the code while its running? ive tried but the light doesnt start to flash.

 

yeah you check that!,.....

 

so while its running i attach a wire at the jumper and itll start to flash?

 

well its supposed to flash when i do this?

 

^yes it is supposed to
Check ronj's signature for more questions on a cel

 

It says to do this while the car is off. The check engine light doesn't come on until my car is running, and when i turn my car off the light doesn't come back on until its running again, so i cant check it with the car off which it says to do in step 4

 

Again, when the CEL turns on, leave the engine running and then jump the service connector to retrieve the code.

 

it doesnt work, ive tried.
