Where is pcm located on 98 Chevy cavalier ls?

The PCM (Powertrain Control Module) on a 1998 Chevy Cavalier LS is typically located under the dashboard, on the driver's side. However, its exact position can vary slightly depending on specific trim levels and options. It's often secured to the firewall or under the dash near the steering column.

To be certain, you should:

* Consult your owner's manual: This is the best source for the exact location.

* Look for a large, rectangular black box: The PCM is usually a fairly large electronic module.

* Use a wiring diagram: This can help you trace the main wiring harness to locate the PCM. You can often find these diagrams online, but a repair manual will have the best diagrams.

It's important to note that accessing the PCM might require removing some trim pieces from under the dashboard. If you're not comfortable working on your car, it's best to take it to a mechanic.
