Solution

1. Preparation

Gather necessary tools and parts.
Tools Required: OBD-II scanner, socket set, torque wrench, oil pressure gauge, oil filter wrench, engine oil, oil catch pan.
Parts Required: Engine oil, oil filter (if needed).
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Change Engine Oil and Filter

Raise the vehicle: Use a jack and secure it with jack stands.
Remove the oil drain plug: Place the oil catch pan under the oil pan and remove the drain plug to drain old oil completely.
- Torque specification for reinstallation: 25 Nm
Replace the oil filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber O-ring on the new oil filter with fresh oil and install it.
- Torque specification for the oil filter: Hand-tight plus 3/4 turn.
Replace the oil drain plug: Reinstall the drain plug and tighten it to the specified torque.

3. Check and Replace Oil Pressure Sending Unit (if necessary)

Locate the oil pressure sending unit: Typically found near the oil filter or on the engine block.
Disconnect the electrical connector: Carefully pull off the connector from the sending unit.
Remove the sending unit: Use a socket or wrench to unscrew it from the engine.
Install the new sending unit: Screw in the new unit and tighten it to the appropriate specification.
Reconnect the electrical connector.

4. Test the Oil Pressure

Connect an oil pressure gauge: Use the gauge to measure oil pressure directly from the engine.
Start the engine: Allow it to idle and observe the pressure reading.
- Normal oil pressure should be between 20-60 psi when the engine is warm.
If pressure is low, further investigate the oil pump or other internal engine issues.
