P0420 – Catalyst System Efficiency Below Threshold (Bank1) is an emission/exhaust-related trouble code reporting inefficient operation of your CAT (catalytic converter). It is important not just to confirm a bad catalytic converter, but also to diagnose why it went bad to prevent damage to a newly installed one as they can cost up to $2000.

Replace the faulty catalytic converter.A P0420 code is typically caused by a problem with the catalytic converter, but it can also be caused by a bad O2 sensor. The rear O2 sensor monitors the catalyst efficiency, so if it fails, it can give a false alarm and cause a P0420 code.

Light stayed off for about a day.o2 sensors are rarely the cause. Vacuum leaks, exhaust leaks (even a pinhole downstream of an o2 sensor can effect the readings). P0420 means that cat isn't working, not necessarily that it is bad. See link below. First step is look at downstream o2 readings. They should be relatively high (over .6V) and steady.

The first step in repairing the OBDII code P0420 for Ford F150 is to diagnose the problem. Most service professionals use an OBD-II scanner to retrieve this code. When the oxygen levels are too high, the PCM will throw the P0420 code. The mechanic will also look for misfires or ignition problems, and will likely check the rear O2 sensor as well.Unfortunately, the P0420 isn't an oxygen sensor problem. Unfortunately, the P0420 is a fairly straight forward code, and a fairly common problem. This code points to a failing Catalytic Converter (for Bank-1). The Oxygen Sensors measure the amount of emissions in the exhaust going into, and then out of the converter.
