Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Check Oil Level

Remove the dipstick, wipe it clean, and reinsert it fully.
Pull the dipstick out again and check the oil level; add oil if below the recommended level.
Use the manufacturer-recommended oil type (typically full synthetic 0W-20).

3. Inspect Oil Pressure Sending Unit

Locate the oil pressure sending unit, usually near the oil filter.
Disconnect the electrical connector from the sending unit.
Remove the sending unit using a socket wrench (typically 1-inch socket).
Replace it with a new sending unit if it appears damaged or faulty.

4. Change Engine Oil and Filter

Drain the old oil by removing the oil drain plug with a socket wrench.
Replace the oil filter using an oil filter wrench; apply a thin layer of new oil to the gasket of the new filter.
Reinstall the oil drain plug and torque to manufacturer specifications (typically around 30 lb-ft).
Fill the engine with new oil through the oil filler cap.

5. Check for Leaks

Start the engine and allow it to run for a few minutes.
Inspect the area around the oil filter and drain plug for any signs of oil leaks.
Monitor the oil pressure warning light; it should turn off if the issue is resolved.
