Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts during the repair.

2. Change Engine Oil and Oil Filter

Drain Old Oil:
- Place an oil catch pan under the oil pan.
- Remove the drain plug using a socket wrench (torque: 30 ft-lb) and allow the oil to fully drain.
Replace Oil Filter:
- Locate the oil filter and use an oil filter wrench to remove it.
- Apply a small amount of new oil to the rubber gasket of the new oil filter.
- Install the new oil filter and tighten it by hand until snug (do not overtighten).
Refill Engine Oil:
- Replace the drain plug and tighten it to the specified torque.
- Using a funnel, pour the recommended type and amount of new engine oil (5W-20 or as specified).
- Start the engine and let it run for a few minutes, then check for leaks around the oil filter and drain plug.

3. Inspect Oil Pressure Sending Unit

Locate the Sending Unit:
- Remove any components blocking access to the oil pressure sending unit.
Test the Sending Unit:
- Disconnect the electrical connector from the sending unit.
- Use a multimeter to check for continuity (should show resistance within specifications).
- If faulty, replace the sending unit with a new one.

4. Inspect Oil Pump (if necessary)

Remove Oil Pan:
- Drain any remaining oil from the oil pan.
- Remove the oil pan bolts using a socket set and carefully lower the pan.
Inspect Oil Pump:
- Check for wear or damage on the oil pump.
- Replace the oil pump if any defects are found.
