Cylinder Compression

WARNING: This page is about a different car, the 2018 Jeep Cherokee. 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.
