WARNING: This page is about a different car, the 2013 RAM 2500 HD and 2012 RAM Pickup. However, it is still accessible from the selected car via links, so may be relevant.
If the Powertrain Control Module (PCM) detects that the variation in crankshaft speed between each cylinder exceeds a calibrated value, based on engine RPM and load, a fault is set.
