Question

What does code p0420 mean for a jeep compass 2007

Answer 1

HI there,

This code is for the bank one catalytic converter efficiency below threshhold. Normally this is going to require a new converter to solve the problem. Sometimes a leaking exhaust or bad rear O2 sensor can cause the problem as well.
