Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick fully and remove it again to check the oil level.
If low, add the appropriate type of oil as specified in the owner’s manual.

3. Inspect Oil Pressure Sending Unit

Locate the oil pressure sending unit (refer to the service manual for exact location).
Disconnect the electrical connector from the sending unit.
Remove the sending unit using a socket wrench.
Install a new oil pressure sending unit if faulty.

4. Test Oil Pressure

Install an external oil pressure gauge by removing the oil pressure sending unit.
Start the engine and observe the oil pressure reading.
The reading should be within the manufacturer's specified range (usually between 25-65 PSI at idle, depending on the engine temperature).
If the pressure is low, proceed to check for potential internal engine issues.

5. Replace Oil Filter

Drain the engine oil by removing the oil drain plug.
Replace the oil filter with a new one, ensuring proper torque.
Refill the engine with the specified oil type and quantity.

6. Reassemble and Test

Reconnect the negative battery terminal.
Start the engine and monitor the dashboard for the oil pressure light.
Check for oil leaks around the oil filter and sending unit.
