Code P0522 Honda Description

The P0522 Honda code indicates that there is a low voltage condition in the engine oil pressure sensor circuit. The engine oil pressure sensor is responsible for monitoring the oil pressure in the engine and sending this information to the vehicle's Engine Control Module (ECM). When the ECM detects a low voltage signal from the oil pressure sensor, it triggers the P0522 trouble code.
