P252C Fault Code

Engine Oil Quality Sensor Circuit Low

• What does that mean?
• Symptoms
• Causes
• Solutions

The Engine Oil Quality Sensor Circuit Low fault code (P252C) indicates that the engine control module (ECM) has detected an issue with the signal from the engine oil quality sensor. This sensor monitors the oil condition and helps ensure that the engine operates smoothly and efficiently. A low signal from this sensor could suggest that the oil is degraded or that there is a malfunction in the sensor's circuit.

What are the symptoms of the P252C code?

• Warning light on the dashboard related to engine oil quality
• Poor engine performance
• Decreased fuel efficiency
• Unusual engine noises from poor lubrication
• Frequent oil changes needed

What causes the P252C code?

• Faulty engine oil quality sensor
• Poor electrical connection in the sensor circuit
• Damaged wiring or connectors
• Low engine oil level or quality
• ECM malfunctions affecting sensor readings

How to fix P252C?

• Inspect and repair or replace the engine oil quality sensor as necessary
• Check the electrical connections and wiring for any damage or corrosion
• Ensure that the engine oil is at the proper level and quality; replace if needed
• Clear the fault codes from the ECM after repairs and reset the warning light
