Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Check and Change Oil

Sub-steps:
1. Remove the dipstick to check oil level; add oil if low (use the manufacturer's recommended oil type).
2. If the oil is dirty or low, drain the old oil by removing the oil drain plug.
3. Replace the oil filter with a new, compatible filter.
4. Refill the engine with the correct type and amount of engine oil.
5. Start the engine and run it for a few minutes, then check for leaks.

3. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove any components obstructing access to the oil pump (refer to service manual).
2. Disconnect the oil pump from the engine block.
3. Inspect the oil pump gears for wear or damage.
4. Install a new oil pump if the old one is defective, ensuring proper alignment.
5. Reassemble any removed components and reconnect the battery.

4. Verify Oil Pressure

Sub-steps:
1. Install a mechanical oil pressure gauge at the engine’s oil pressure sending unit location.
2. Start the engine and observe the pressure reading at idle; it should meet the manufacturer's specification.
3. If the pressure is still low, further investigation into engine wear may be necessary.
