Solution
1. Preparation
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Gather necessary tools and parts.
  • Disconnect the battery to prevent electrical shorts.
2. Change Engine Oil and Filter
  • Tools Required: Socket set, oil filter wrench, drain pan
  • Drain the engine oil by removing the drain plug using a socket wrench. Allow oil to fully drain into the pan.
  • Replace the oil filter: use the oil filter wrench to remove the old filter, lubricate the rubber gasket of the new filter with fresh oil, and install it.
  • Reinstall the drain plug and torque it to the manufacturer’s specifications (usually around 25 Nm).
  • Refill the engine with the appropriate oil type (refer to the owner's manual for oil specifications).
3. Replace Oil Pressure Sending Unit (if faulty)
  • Tools Required: Socket set, torque wrench
  • Locate the oil pressure sending unit (usually near the oil filter).
  • Disconnect the electrical connector and remove the sending unit using a socket wrench.
  • Install the new sending unit and torque it to the manufacturer's specifications.
  • Reconnect the electrical connector.
4. Inspect and Repair Oil Pump (if necessary)
  • Tools Required: Socket set, torque wrench, oil pump gasket
  • If the oil pressure gauge indicated low pressure and the sending unit is functional, the oil pump may need inspection.
  • Remove the oil pan to access the oil pump (ensure to drain oil first).
  • Inspect the oil pump for wear and replace with a new pump if necessary, ensuring correct alignment and torque specifications during installation.
  • Replace the oil pan with a new gasket and torque to specification.
