Solution

1. Preparation

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

2. Check and Add Engine Oil

a. Remove the oil filler cap and check the oil level on the dipstick.
b. If low, add the appropriate type and grade of oil recommended by the manufacturer until the level is correct.

3. Inspect and Replace Oil Filter

a. Place an oil catch pan under the oil filter.
b. Remove the old oil filter using an oil filter wrench.
c. Apply a thin layer of new oil to the rubber gasket of the new filter.
d. Install the new oil filter, tightening it according to the manufacturer's specifications.

4. Replace Oil Pressure Sensor

a. Locate the oil pressure sensor on the engine block (consult service manual for specific location).
b. Disconnect the electrical connector from the sensor.
c. Remove the sensor using a socket or wrench.
d. Install the new oil pressure sensor and reconnect the electrical connector.

5. Test Oil Pressure

a. Remove the oil pressure sending unit and install a mechanical oil pressure gauge.
b. Start the engine and observe the gauge reading; it should be within the manufacturer's specified range.
c. If the reading is low, further investigation may be needed, such as checking for oil pump failure.
