Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Check Oil Level and Condition

Remove the dipstick, wipe it clean, and reinsert it fully.
Pull it out again to check the oil level; add oil if low.
Inspect the oil's color and consistency. If it's dark and sludgy, consider an oil change.

3. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector from the sending unit.
Use a socket wrench to remove the old sending unit.
Apply thread sealant to the new sending unit and install it.
Reconnect the electrical connector.

4. Change Engine Oil and Filter

Place an oil drain pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
Replace the oil drain plug and torque it to the manufacturer’s specification (usually around 20 Nm).
Remove the old oil filter using an oil filter wrench and install a new one.
Fill the engine with the correct type and amount of oil (consult the owner's manual for specifications).

5. Recheck Oil Pressure

Reconnect the battery.
Start the engine and let it idle.
Check the oil pressure gauge or warning light to ensure it’s within normal operating range.
