How does the P0420 Chevrolet catalyst system low efficiency Bank 1?
How does the P0420 Chevrolet catalyst system low efficiency Bank 1?
The catalyst within the converter promotes a chemical reaction which oxidizes the HC and CO present in the exhaust gas. This reaction converts them into harmless water vapor and Carbon Dioxide. The catalyst also reduces NOx, converting it to Nitrogen. The Powertrain Control Module (PCM) monitors this process using Bank1 HO2S #2.
