Detailed Guide for Replacing the Oil Pressure Sensor on a 2012 Dodge Grand Caravan
The oil pressure sensor in a 2012 Dodge Grand Caravan plays a crucial role in monitoring the engine’s oil pressure and providing vital information to the vehicle’s computer system. When this sensor fails, it can trigger a check engine light and various performance issues. In this comprehensive guide, we’ll walk you through the steps to replace the oil pressure sensor, including the correct socket size, installation process, and troubleshooting tips.
What is the Correct Size of the Oil Pressure Sensor Socket?
The correct size of the oil pressure sensor socket for a 2012 Dodge Grand Caravan is a 1-1/16″ deep well thin wall socket. This specialized socket is necessary due to the tight space around the oil pressure sensor, which is located between the engine heads, behind the oil cooler housing.
How to Replace the Oil Pressure Sensor?
Tools and Materials Needed:
– 1-1/16″ deep well thin wall socket: Available on Amazon for approximately $6.
– 6″ socket wrench extension: To reach the sensor.
– Genuine Mopar Oil Pressure Sensor: Part# 0514 9062 AB-001. Recommended to purchase from a Dodge dealership or online retailers like Amazon or eBay, costing around $75.
Steps:
1. Locate the Oil Pressure Sensor: The sensor is situated between the heads, behind the oil cooler housing.
2. Remove the Sound Plastic Piece: Take off the sound plastic piece on top of the engine to access the area.
3. Identify the Sensor: Look for the hose and aluminum wires leading to the sensor. The sensor is above the bottom hose.
4. Disconnect the Electrical Connector: Carefully disconnect the electrical connector from the oil pressure sensor.
5. Remove the Old Sensor: Use the 1-1/16″ deep well thin wall socket and 6″ extension to remove the old sensor. Be cautious not to damage the threads.
6. Install the New Sensor: Apply the red thread sealant to the new sensor and screw it into place using the same socket and extension. Ensure it is securely tightened.
7. Reconnect the Electrical Connector: Connect the electrical connector back to the new oil pressure sensor.
8. Replace the Sound Plastic Piece: Put back the sound plastic piece on top of the engine.
What are the Engine Oil Pressure Circuit and Components?
The engine oil pressure circuit in a 2012 Dodge Grand Caravan includes:
– Oil Pump: A two-stage oil pump that circulates oil throughout the engine.
– Oil Filter: Ensures clean oil is circulated. Use OEM filters to avoid issues.
– Oil Cooler: Helps in cooling the engine oil. The oil pressure sensor is located behind this housing.
– Oil Pressure Sensor: Monitors the oil pressure and sends signals to the engine control module (ECM).
How to Troubleshoot the P0520 Code?
P0520 Code: Indicates an issue with the oil pressure sensor circuit.
Troubleshooting Steps:
1. Check the Oil Level and Condition: Ensure the oil level is adequate and the oil is not degraded.
2. Verify the Oil Filter: Use an OEM oil filter to avoid compatibility issues.
3. Inspect the Electrical Connector: Check for any damage or corrosion on the electrical connector of the oil pressure sensor.
4. Replace the Oil Pressure Sensor: If the above steps do not resolve the issue, replace the oil pressure sensor following the steps outlined above.
5. Check the Oil Pump: If the issue persists, it may indicate a problem with the oil pump, which is a more invasive repair.
