Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, oil pressure gauge, oil filter wrench, clean rags.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery for safety.

2. Change Oil and Filter

Step 1: Drain the old oil.
- Place a drain pan under the oil pan and remove the drain plug with the socket set. Allow oil to completely drain.
Step 2: Replace the oil filter.
- Use the oil filter wrench to remove the old oil filter. Apply a thin layer of new oil to the rubber gasket of the new filter. Install the new filter by hand until snug, then tighten according to the manufacturer's specifications.
Step 3: Refill with new oil.
- Replace the drain plug and tighten it. Using a funnel, pour the manufacturer-recommended oil into the engine through the oil filler cap. Use the correct oil type and viscosity as specified in the owner's manual.

3. Replace Oil Pressure Sending Unit (if necessary)

Step 1: Locate the oil pressure sending unit.
- Typically near the oil filter or on the engine block. Consult the service manual for exact location.
Step 2: Disconnect the electrical connector.
Step 3: Remove the old sending unit using the appropriate socket or wrench.
Step 4: Install the new sending unit.
- Apply thread sealant to the threads and tighten to the manufacturer's specifications.
