Question

Answer 1

Hi there,

This code is for the bank 1 catalytic converter. Most of the time the converter is the cause of the problem. Sometimes you can also have a problem with an exhaust leak or rear O2 sensor on that bank causing the problem as well.

The other code is for the intake air temp sensor.
