Re: CEL on
Which engine, 3800 or 3.1? Disconnecting the battery will not reset odb-ii DTC error codes and the SES/CEL light. You need a scanner/code reader which will hook up to the data port under the steering column. Places like Autozone will scan for free and list the DTC error codes for corrective action. It is important to see why the SES light has illuminated and normally it is an emissions related problem.
Lynn, didn't know you have this covered. Our posts were at the same time.
