Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shorts while working on the vehicle.

2. Verify Oil Change Installation

Check the oil filter:
- Remove the oil filter using an oil filter wrench.
- Inspect the rubber O-ring for any damage or remnants from the old filter.
- Ensure the new filter is seated properly and re-install it hand-tight.
Check the drain plug:
- Inspect the drain plug for proper torque (usually 20-30 lb-ft).
- Ensure a new washer is installed if required.

3. Inspect the Oil Pressure Sensor

Locate the oil pressure sensor, typically near the oil filter.
Disconnect the electrical connector from the sensor.
Use a multimeter to check the sensor resistance and ensure it is within specifications.
If faulty, replace the oil pressure sensor.

4. Reset the Check Engine Light

Reconnect the battery.
Use the OBD-II scanner to clear the error codes.
Start the engine and allow it to idle, monitoring for any warning lights.
