Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check Oil Level

Open the hood and locate the oil dipstick.
Remove the dipstick, clean it with a lint-free cloth, reinsert it, and remove it again to check the oil level.
If low, add the correct type of oil as per manufacturer's specifications.

3. Inspect Oil Pressure Sensor

Locate the oil pressure sensor, typically found near the oil filter or engine block.
Disconnect the electrical connector from the sensor.
Remove the sensor using a socket wrench; inspect for damage or leaks.
Replace with a new sensor if necessary.

4. Replace Oil Filter and Oil

Place an oil catch pan under the oil pan.
Unscrew the oil filter using an oil filter wrench; allow oil to drain completely.
Install a new oil filter, ensuring the rubber O-ring is lubricated with new oil.
Drain the old engine oil from the pan and replace it with new oil, using the correct viscosity as per Tesla specifications.

5. Test Oil Pressure

Reconnect the battery and start the engine.
Use a mechanical oil pressure gauge by removing the oil pressure sensor and installing the gauge.
Monitor the pressure readings to ensure they are within the proper range.
