Cylinder Compression

WARNING: This page is about a different car, the 2015 RAM ProMaster 3500, 2015 RAM ProMaster 2500, and 2015 RAM ProMaster 1500. However, it is still accessible from the selected car via links, so may be relevant.

The PCM cannot detect uneven, low, or high engine cylinder compression. Low compression lowers O2 content in the exhaust. Leading to fuel system, oxygen sensor, or misfire detection fault.
