– Engine Light ON (or Service Engine Soon Warning Light) – Oil pressure warning light ON.
Causes Causes of the OBD-II code P0521
– Low oil level or motor mechanical fault – Open or short oil level sensor circuit condition – Poor oil level sensor electrical connection – Faulty oil pressure sensor The Error code is generally activated on detection of the following conditions: The P0521 is detected when the signal sent from oil pressure sensor to PCM goes out of range.
– Low oil level or motor mechanical fault – Open or short oil level sensor circuit condition – Poor oil level sensor electrical connection – Faulty oil pressure sensor The Error code is generally activated on detection of the following conditions: The P0521 is detected when the signal sent from oil pressure sensor to PCM goes out of range.
Solutions The most likely cause is a faulty oil pressure sensor/switch
