Is a stored code bad?

How can I check if my check engine light is on?

If your “check engine light” is on and your mechanic says you need some expensive repair, there is an easy way for you to check if he is telling the truth.

What does code 12 on Check Engine light mean?

Code 12 indicates a problem with my EGR system. This is the system that sends some of the engine’s exhaust into the cylinder to cool the combustion process and keep temps in the cylinders down. Having a broken EGR is relatively common on a high mileage car (I have 180,000 miles on mine) and it’s a pretty easy fix.

How can I tell if my lamp is a cel?

You need to find out which pin on the connector to the engine computer is for the CEL. Then check for continuity from the lamp socket to the computer connector. Also one pin of the lamp socket goes to ground, check this continuity too. If all that checks out then it’s a problem in the computer module (lamp driver).
