Question

Answer 1

Hi there,

The P0420 code is for the bank 1 catalytic converter below threshold. Typically the problem is the converter itself. Depending on the size of the engine would indicate which bank the converter is on. Sometimes a bad rear O2 sensor can cause the problem or exhaust leaks will do it too.
