Ensure the vehicle is parked on a level surface, and the engine is turned off and cool.
Disconnect the battery to prevent any electrical issues.

2. Check and Replace Engine Oil

Sub-steps:
1. Remove the oil fill cap and check the oil level using the dipstick.
2. If the oil level is low, add the appropriate type and viscosity oil as per the owner's manual.
3. If the oil is dirty or contaminated, drain the old oil by removing the oil drain plug and allow it to fully drain into a pan.
4. Replace the oil filter using an oil filter wrench.
  - Tools Required: Socket set, oil filter wrench, oil catch pan
  - Safety Warnings: Allow the engine to cool before draining oil to avoid burns.

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit on the engine, typically near the oil filter or on the engine block.
2. Disconnect the electrical connector and unscrew the sending unit using a socket wrench.
3. Install the new sending unit and ensure it is tightened securely.
4. Reconnect the electrical connector.
  - Tools Required: Socket set, torque wrench
  - Torque Specifications: Tighten to manufacturer specifications (refer to service manual).

4. Inspect Oil Pump

Sub-steps:
1. If low oil pressure persists, check the oil pump for proper operation.
2. Remove the oil pan to access the oil pump.
3. Inspect the oil pump for wear and tear; replace if necessary.
  - Tools Required: Socket set, oil pan gasket
  - Safety Warnings: Ensure all oil is drained before removing the oil pan.
