Solution

1. Preparation

Tools Required: OBD-II scanner, oil pressure gauge, socket set, torque wrench, oil filter wrench, rags for cleanup.
Safety Warnings: Allow the engine to cool before beginning work. Disconnect the battery to avoid electrical issues.

2. Replace Oil Pressure Sensor

Sub-steps:
1. Locate the oil pressure sensor as per the service manual.
2. Disconnect the electrical connector from the sensor.
3. Use a socket wrench to remove the sensor from the engine block.
4. Install the new sensor and tighten it to the manufacturer's specifications (usually around 15-20 ft-lbs).
5. Reconnect the electrical connector.

3. Change Engine Oil and Oil Filter

Sub-steps:
1. Place a drain pan under the oil pan and remove the drain plug. Allow the old oil to fully drain.
2. Remove the old oil filter using the oil filter wrench.
3. Apply a thin layer of fresh oil on the rubber gasket of the new oil filter.
4. Install the new oil filter and tighten it according to the manufacturer's specifications (usually hand-tight plus a quarter turn).
5. Replace the drain plug and tighten it securely.
6. Refill the engine with the correct type and amount of oil as specified in the owner’s manual.

4. Test Oil Pressure

Sub-steps:
1. Reconnect the battery and start the engine.
2. Allow the engine to reach normal operating temperature.
3. Use the oil pressure gauge to check the oil pressure at idle and higher RPMs, ensuring it meets manufacturer specifications.
