Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, oil pressure gauge, torque wrench, oil filter wrench.
Safety Warnings: Disconnect the battery before starting work, and allow the engine to cool before opening any components.

2. Check and Top Off Oil Level

Locate the dipstick and remove it.
Wipe it clean and reinsert it, then remove again to check the oil level.
If low, top off with the manufacturer-recommended engine oil.

3. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter, ensuring it is snug but not overtightened.

4. Test Oil Pressure

Remove the oil pressure sending unit using a socket set.
Install the oil pressure gauge in the same location.
Start the engine and check the pressure reading; it should be within the specified range (consult the owner’s manual for correct values).
If the pressure is low, it may indicate a failed oil pump or internal engine wear.

5. Replace Oil Pressure Sending Unit (if necessary)

If the oil pressure gauge shows normal readings but the warning light remains, replace the oil pressure sending unit.
Disconnect the wiring harness and unscrew the unit from its location.
Install the new sending unit and reconnect the wiring harness.

6. Clear Codes and Recheck

Use the OBD-II scanner to clear any diagnostic trouble codes.
Start the engine and monitor the oil pressure light to ensure it remains off.
