my Tesla Model S Plaid/Refresh (2021-present) has a P0131 code, what does that indicate

• •Check engine light illuminated
• •Reduced fuel efficiency
• •Poor engine performance or rough idling
• •Increased emissions
• •Unusual exhaust smells (rich fuel odor)

1. 1Scan the vehicle's OBD-II system to confirm the P0131 code and check for any other related codes.
2. 2Inspect the wiring and connectors of the oxygen sensor for damage, corrosion, or loose connections.
3. 3Measure the voltage output of the oxygen sensor using a multimeter while the engine is running.
4. 4Check the vehicle's fuel trim readings to see if they are out of the normal range.
5. 5Inspect the exhaust system for leaks that may affect sensor readings.
6. 6Replace the oxygen sensor if it is found to be faulty based on the voltage readings and visual inspection.

After completing the repair, verify that the issue has been resolved:

• ✓Test the affected component to ensure it functions correctly
• ✓Check for any error codes or warning lights
• ✓Monitor the vehicle for a few days to ensure the issue does not recur

To prevent this issue from occurring again:

• •Follow the manufacturer's recommended maintenance schedule
• •Address warning signs early before they develop into major issues
• •Use quality parts and fluids recommended for your vehicle
• •Keep detailed records of all repairs and maintenance

• •OBD-II scanner
• •Multimeter
• •Oxygen sensor socket
• •Torque wrench
• •Basic hand tools (sockets, wrenches)

• •Oxygen sensor (specific to model and engine configuration)
