Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues.

2. Check and Add Oil

Tools Required: Oil filter wrench, funnel, new oil.
If the oil level is low, add the correct type of oil as specified in the owner's manual.
Start the engine and check for oil pressure light status after adding oil.

3. Replace Oil Pressure Sending Unit (if faulty)

Tools Required: Socket set, torque wrench, oil catch pan.
Locate the oil pressure sending unit (usually near the oil filter or on the engine block).
Remove the electrical connector from the sending unit.
Unscrew the sending unit using a socket wrench.
Install the new sending unit, ensuring it is tightened to the manufacturer's torque specifications.
Reconnect the electrical connector.

4. Replace the Oil Filter and Change Oil (if contaminated)

Tools Required: Oil filter wrench, oil catch pan, socket set, funnel.
Place the oil catch pan under the oil pan and remove the oil drain plug to drain old oil.
Remove the old oil filter using the oil filter wrench.
Install the new oil filter, applying a thin layer of oil on the rubber gasket for a better seal.
Replace the drain plug and refill the engine with new oil.

5. Reconnect Battery and Test

Reconnect the battery.
Start the engine and allow it to idle for a few minutes.
Check for the low oil pressure warning light and monitor oil pressure.
