P0523 PONTIAC Possible Causes
- Low oil level or motor mechanical fault
- Faulty Oil Pressure sensor
- Oil Pressure Sensor harness is open or shorted
- Oil Pressure Sensor circuit poor electrical connection
How do I fix code P0523 PONTIAC?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P0523 PONTIAC code
The cost of diagnosing the P0523 PONTIAC code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
The P0522 is set when the Powertrain Control Module (PCM) senses a signal voltage higher than the normal operating range of the Engine Oil Pressure (EOP) sensor
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Oil pressure warning light ON
P0523 PONTIAC Description
The Powertrain Control Module (PCM) continuously monitors the Engine Oil Pressure (EOP). The EOP sensor measure cahnges in the oil pressure. The EOP sensor changes resistance base on the engine oil pressure.
