This is why when it comes to locating your ECM it's best to consult your vehicle's owner's manual to find the exact location, but typically they are found in the engine compartment, under the passenger floorboard, under the seats, or behind the kick panels.

Where is the PCM located at?

PCM stands for powertrain control module, aka the ecu. It is located in the console just under the radio. If you pull the side panel from the console, you will see it bolted to the metal console frame.

How do I know if my powertrain control module is bad?

Several symptoms may indicate your ECM is damaged, ranging from poor engine performance to failed ignition, increased emission, loss of gas mileage, fuel inefficiency and erratic transmission, among others. Symptoms are also overlapping and some may result from bad trouble codes or actual physical damages to the unit.
