Maf Sensor P0420 at Phyllis Gordon blog

Maf Sensor P0420. P0420 code means the catalytic converter is not working properly to reduce emissions. The p0420 code means your car’s catalytic converter on one side of the engine isn’t cleaning up pollution as well as it should. Learn how to diagnose and fix this. And the engine control unit (ecu) will register p0420 and display a check engine light to notify the driver of imminent issues in the engine. If the downstream sensor starts fluctuating like the upstream, it indicates there’s too much oxygen in the engine. First to verify the presence of the p0420 and/or p0430 dtcs but to also check for any others that might be recorded in the ecm. This sensor measures the amount of air entering the engine. Any dtc or condition that increases emissions or affects sensor readings can cause a converter to fail the ecm tests even if the converter is good. Mass air flow (maf) sensor data. Dtc p0420 means the catalytic converter isn’t removing enough pollutants from the engine’s bank 1. Often, this is due to a bad catalytic converter, but parts like oxygen sensors.
