What causes the P0420 trouble code on a Honda Ridgeline?
There are many things that can cause the P0420 trouble code in your Ridgeline. Here are the most common ones. Oxygen Sensor – The P0420 codes is thrown when the oxygen sensors on both sides of the exhaust have very similar readings. When the oxygen sensor is bad, it can cause a false reading and trigger the code.
What does the OBDII code P0420 stand for?
P0420 is a OBDII trouble code. The code technically stands for: Catalyst System Efficiency Below Threshold. Your Ridgeline has at least two oxygen sensors, one before and after the catalytic converter. Among the many jobs that oxygen sensors have is they have to measure the emissions levels coming in and out of the converter.
