Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery for safety.

2. Check Oil Level and Condition

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the manufacturer's recommended oil type until the correct level is reached.
If the oil appears dirty or contaminated, proceed to change the oil.

3. Change Engine Oil and Filter

Tools Required: Wrench set, oil filter wrench, oil catch pan
Place the oil catch pan under the oil pan.
Remove the oil drain plug using the wrench and allow the old oil to drain completely.
Replace the oil filter using the oil filter wrench, ensuring the old O-ring is removed.
Reinstall the drain plug and torque to the manufacturer's specifications (typically 30-40 ft-lbs).
Fill the engine with the appropriate type and amount of new oil (check owner's manual for specification).

4. Replace Oil Pressure Sensor (if necessary)

Locate the oil pressure sensor, usually found on the engine block.
Disconnect the electrical connector from the sensor.
Remove the sensor using a wrench.
Install the new oil pressure sensor and reconnect the electrical connector.

5. Test Oil Pressure

Start the engine and allow it to reach operating temperature.
Reconnect the oil pressure gauge to check if oil pressure is within the normal range (typically between 25-65 PSI at idle).
