Solution

1. Preparation

Gather tools: oil pressure gauge, socket set, wrenches, oil filter wrench, new oil filter, and engine oil.
Ensure the vehicle is parked on a level surface and the engine is off and cool.
Disconnect the battery to prevent any electrical issues while working.

2. Check and Replace Engine Oil

Remove the oil drain plug using the socket set and allow old oil to drain completely into a pan.
Replace the oil filter using the oil filter wrench.
Install the new oil filter, ensuring it is properly tightened (hand-tight plus a quarter turn).
Reinstall the oil drain plug and torque to the manufacturer's specifications (usually around 25-30 Nm).
Fill the engine with the appropriate type and amount of new oil as specified in the owner's manual.

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

Locate the oil pressure sending unit, typically near the oil filter.
Disconnect the electrical connector from the sending unit.
Use a wrench to unscrew the old sending unit and remove it from the engine.
Install the new sending unit and tighten it to manufacturer specifications.
Reconnect the electrical connector.

4. Final Checks

Reconnect the battery.
Start the engine and allow it to idle for a few minutes.
Check the oil pressure gauge to ensure that oil pressure has returned to normal levels.
