2022年3月16日 · The P0056 code stands for “HO2S Heater Control Circuit Bank 2 Sensor 2,” which means the powertrain control module (PCM) detects a possible issue with the heater control circuit of oxygen sensor 2 on Bank 2.

2025年2月1日 · The P0056 code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor heater control circuit for Bank 2 Sensor 2. This specific sensor plays a crucial role in monitoring exhaust emissions and ensuring optimal fuel efficiency.

2024年3月23日 · The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it takes the sensor to warm up and start sending an adequate signal. The code is set when the sensor is taking too long to warm up.

The P0056 code refers to the sensor after the catalytic converter on Bank 2, which is on the side of the engine that does NOT contain the #1 cylinder. The heater circuit may be supplied power or ground by the PCM/ECM or another source that can be controlled by the PCM/ECM.

One common cause of the P0056 code is a faulty or broken oxygen sensor. The oxygen sensor’s primary function is to measure the oxygen content in the exhaust gasses after leaving the...
