Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat 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 filler cap and check the oil level using the dipstick.
2. If the oil is low or dirty, drain the old oil using an oil pan.
  - Tools Required: Oil drain pan, socket set.
3. Replace the oil filter with a new one.
  - Tools Required: Oil filter wrench.
4. Refill the engine with the manufacturer's recommended oil type and viscosity.
  - Parts Required: Engine oil (5W-20 or as specified), oil filter.

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit, typically found near the oil filter.
2. Disconnect the electrical connector from the sending unit.
3. Use a socket wrench to remove the sending unit.
4. Install the new sending unit and tighten it to the manufacturer's specifications (usually around 15-20 lb-ft).
5. Reconnect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan by loosening the bolts and carefully prying it off.
2. Inspect the oil pump for wear, damage, or blockage.
3. If replacement is needed, unbolt the oil pump from the engine and install a new pump.
  - Torque Specification: Follow the manufacturer's torque specifications for the oil pump bolts.
4. Reinstall the oil pan with a new gasket and torque the bolts to the specified value.
