Powertrain control module for the 2008 Jeep Compass with the 2.4L World Engine. The MK-platform Compass and Patriot use a controller located on the driver-side firewall, inboard of the fuse box, accessible by removing the air filter housing.

This PCM manages the Chrysler World Engine (2.4L DOHC) and continuously variable transmission (CVT) or 5-speed manual, depending on configuration. The 2.4L variant uses variable valve timing on both intake and exhaust camshafts, requiring precise PCM calibration for oil temperature-dependent VVT scheduling.

Common failure symptoms on Compass/Patriot: CVT ratio error codes (P0868, P0730) that persist after fluid service, rough idle with P0300 random misfire at cold start, and intermittent no-crank condition caused by internal PCM relay failure. Pre-programmed to your VIN with immobilizer sync included.
