Code P2244 Acura Description
The P2244 diagnostic trouble code (DTC) for Acura vehicles specifically refers to an issue with the O2 sensor reference voltage performance on Bank 1 Sensor 1. The O2 sensor, also known as the oxygen sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases to ensure the optimal air-fuel ratio for combustion in the engine. Bank 1 Sensor 1 is typically located in the exhaust manifold before the catalytic converter.
