P0432: what does this code mean?
Catalytic converter efficiency below threshold (bank 2)
Parts to check, to be confirmed by diagnosis
- Catalytic converterSearch for my vehicle
- Oxygen sensorSearch for my vehicle
Good to know: Do not order the catalytic converter straight away: first have the downstream oxygen sensor checked and look for an exhaust leak upstream.
Bank 1: the side of the engine with cylinder 1. An inline engine has only one bank.
A code points to a circuit or a function, not a part number: confirm by diagnosis before ordering.
