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 prevent electrical issues.

2. Inspect and Secure Connections

Sub-steps:
- Locate the oil pressure sensor wire and ensure it's connected securely.
- Check the connections on the oil filter and ensure it is tight.
- Recheck the drain plug for proper torque (typically around 30 ft-lbs for a Camry).

3. Change Engine Oil (if necessary)

Sub-steps:
- Remove the old oil filter using an oil filter wrench.
- Install the new oil filter, applying a small amount of new oil to the rubber gasket.
- Drain the old oil from the oil pan and replace it with new oil, ensuring to use the correct oil type (5W-20 for most models).
- Start the engine and let it run for a few minutes, checking for leaks around the filter and drain plug.

4. Clear Error Codes

Sub-steps:
- Use the OBD-II scanner to clear any stored error codes after confirming repairs.
- Reconnect the battery.
