Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Check and Top-off Engine Oil

Remove the oil filler cap.
Using a funnel, add the appropriate type and grade of oil if the level is low.
Replace the oil filler cap securely.

3. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit; it is typically near the oil filter or on the engine block.
Use a socket set to disconnect the wiring harness from the sending unit.
Unscrew the old sending unit using a wrench.
Apply a small amount of oil to the O-ring of the new sending unit.
Install the new sending unit by screwing it into place and reconnecting the wiring harness.

4. Change Engine Oil and Filter

Place an oil catch pan under the oil pan.
Remove the oil drain plug using a wrench and allow the old oil to completely drain.
Replace the oil drain plug and tighten it to the manufacturer’s specified torque.
Remove the old oil filter using an oil filter wrench.
Apply oil to the O-ring of the new oil filter and install it.
Fill the engine with the correct amount of new oil through the oil filler cap.

5. Final Checks

Reconnect the battery.
Start the engine and allow it to idle while checking for leaks around the oil filter and sending unit.
Monitor the oil pressure warning light; it should turn off if the issue is resolved.
