Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off and cooled down.
Wear safety gloves and goggles.

2. Check and Replace Engine Oil

Sub-step 1: Locate the oil filler cap and remove it.
Sub-step 2: Use the dipstick to check the oil level. If low, add the appropriate oil type (5W-30 or as specified in the owner’s manual).
Sub-step 3: If oil quality is poor (dirty or contaminated), drain the old oil using a socket set to remove the oil drain plug.
Sub-step 4: Replace the oil filter using an oil filter wrench and ensure the rubber O-ring is replaced with the new filter.
Sub-step 5: Refill the engine with new oil to the recommended level and replace the oil filler cap.

3. Inspect and Replace Oil Pressure Sensor (if necessary)

Sub-step 1: Disconnect the battery to avoid any electrical issues.
