Hello,

The PCM is located on the passengers side under the hood. Here is a diagram that will give you a better idea (below).

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

Your vehicle's Powertrain Control Module (PCM) is located under the right side of the dash, behind the convenience center

Car just stopped. Will turn over but will not run. I do not have a manual but am told to try replacing the control module first. Need to know where to look for it.

Just because it wont start doesnt mean any control module is bad!

Does the engien crank?

If it cranks first thign to do is get checking out for spark on ALL cylinders note color of spark and speed of spark.

Next check for fuel pressure.

Let me know what you find.

I need to replace my PCM. Where is it located? To my understanding it is just simply removeing the old one and pluging in the new. Anything you might add. Thanks
