P0420 Catalyst efficiency

The P0420 is a very common problem on just about every make and model these days. Unfortunately, more times than not the correct repair is going to be to replace the Catalytic Converter.

Is your Check Engine light on?

When the Check Engine light comes on, this is the on-board computer’s way of telling you it sees a problem in one of the monitored systems. Unfortunately, there are literally 100’s of parts and sensors monitored in various systems, and to take a “guess” as to which part/sensor in which system is faulty, is virtually impossible. However, if you are not experiencing any drivability issues such as skipping, stalling, shifting problems, etc, then more than likely, the problem is going to lie in the EVAP (emissions control/recovery) system.

Dodge/Chrysler/Jeep self-diagnosis

On most Dodge, Chrysler and Jeep models built after 2000, with a digital odometer can run a self-diagnostic and display OBD-II p-codes. Let’s give it a try….

When the shifter will not move from Park, first, check your rear brake lights, and see if they are working when you step on the brake pedal.

Inspect the electrical connector and wire harness for any loose, broken…
