Check Engine Light Code P0420 at Danelle Perez blog

Check Engine Light Code P0420. Basically, bank 1 and bank 2 are the two sides of the engine. The p0420 code indicates that your vehicle’s powertrain control module (pcm) monitors the poor efficiency of the catalytic converter at bank 1. The most common symptom is the illumination of the check engine light on your vehicle's dashboard. Beyond a bad “cat,” a p0420 code can be triggered for many reasons. Diagnostic trouble code (dtc) p0420 stands for “p0420 catalyst system efficiency below threshold (bank 1).” it indicates that the exhaust system’s oxygen levels are below the required threshold in bank 1, which can damage the engine’s exhaust and fuel system. This code may also be triggered due to a bad catalyst or a false alarm caused by a faulty oxygen sensor at bank 1. If the downstream sensor starts fluctuating like the upstream, it indicates there’s too much oxygen in the engine. It refers to catalytic converter efficiency basically, it engine. Check out the fixd article on the most common causes of check engine lights. P0420 is probably the most common code seen. You’ll want to get to the root of the problem to ensure emissions compliance, restore proper engine operations, and minimize damage risk. This light indicates that there's a general problem with the engine, or the emissions control system and catalytic converter. 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.
