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 any electrical issues during the repair.

2. Check Oil Level and Quality

Remove the dipstick and wipe it clean with a lint-free cloth.
Reinsert the dipstick fully and then withdraw it to check the oil level.
If the oil level is low, add the appropriate type of oil to reach the recommended level.
If oil quality is poor, proceed to the next step.

3. Change Engine Oil and Filter

Remove the oil drain plug using a socket wrench and allow the old oil to drain into a suitable container.
Replace the oil filter using an oil filter wrench; apply a small amount of new oil to the rubber gasket of the new filter before installation.
Reinstall the drain plug and torque it to the manufacturer's specifications.
Fill the engine with new oil as per the manufacturer’s specifications.

4. Replace Oil Pressure Sensor (if necessary)

Locate the oil pressure sensor, typically found on the engine block.
Disconnect the electrical connector and remove the sensor using a wrench.
Install the new oil pressure sensor and reconnect the electrical connector.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and let it idle for a few minutes.
Check for any oil leaks and ensure the oil pressure warning light is off.
