Hello,

The engine control module is located under the hood on the passengers side by the firewall. Here is a diagrams (Below) so you can see what I am talking about.

Check out the diagrams (Below)

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

Cheers, Ken

I need to try plug/unplug the pcm cable for possible corrosion issue causing intermittent. Where do I find that plug?

At the pcm module youdo take it off it will have a clamp that can either be bolted or a movable clamp. Put some dielectric grease on the pins.

Powertrain control module (PCM) is commonly referred to as the vehicle's "brain". It sends important signals to components of the vehicle in order for the engine to fire up and run properly. It is mounted through the firewall and is most likely going to cost approx. $500 to purchase and have replaced
