Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the 12V battery to prevent electrical issues during repairs.
Gather necessary tools and parts.

2. Oil Level and Quality Check

Remove the oil filler cap and check the oil level.
If low, add the recommended oil type (e.g., Tesla-approved synthetic oil).
If the oil is dirty or contaminated, proceed to the oil change step.

3. Oil Change

Tools Required: Oil wrench, socket set, oil catch pan, funnel.

Lift the vehicle using a lift or jack stands.
Place an oil catch pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow old oil to drain completely.
Replace the drain plug and torque to manufacturer's specifications (usually around 25-30 ft-lbs).
Replace the oil filter using an oil filter wrench; apply a thin layer of new oil on the new filter gasket before installation.
Refill with new oil through the oil filler cap using a funnel.

4. Sensor Inspection

Reconnect the battery.
Locate the oil pressure sensor and disconnect its electrical connector.
Use a multimeter to check the resistance across the sensor terminals; compare readings to manufacturer's specifications.
If faulty, replace the oil pressure sensor.

5. Oil Pump Inspection (if necessary)

If low oil pressure persists, inspect the oil pump:

Remove any components obstructing access (e.g., engine covers).
Disconnect the oil pump and remove it for inspection.
Check for wear or damage; replace if necessary.
