Solution

1. Preparation

Gather necessary tools and parts.
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 and Change Oil

Sub-steps:
1. Remove the oil fill cap and check the condition of the oil.
2. If oil is dirty or low, drain the old oil using an oil pan.
3. Replace the oil filter with a new one; ensure the rubber O-ring is removed from the old filter.
4. Fill with the recommended oil type and quantity (typically SAE 5W-20 for this engine).
5. Run the engine for a few minutes, then check the oil level again and top off if necessary.

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector from the sending unit.
3. Use a socket to unscrew the old sending unit and replace it with a new one.
4. Reconnect the electrical connector and ensure it is secure.

4. Test Oil Pump

Sub-steps:
1. If low oil pressure persists, remove the oil pan to access the oil pump.
2. Inspect the oil pump for wear; if damaged, replace it with a new pump.
3. Reassemble the oil pan using new gasket material and torque to manufacturer specifications.
