Learn how to diagnose and fix P0135 oxygen sensor heater issues in Tesla Outback 5th Generation. Step-by-step guide with diagnostic procedures and repair instructions.

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the negative terminal of the battery to ensure safety.

2. Replace Oxygen Sensor

1. Locate the oxygen sensor:

   • Find the specific location of the oxygen sensor related to the P0135 code, typically found in the exhaust system, upstream of the catalytic converter.

2. Remove the old oxygen sensor:

   • Use an oxygen sensor socket or a wrench to carefully unscrew the sensor from its mounting location.
   • Be cautious of exhaust heat; allow the exhaust to cool if necessary.

3. Install the new oxygen sensor:

   • Apply anti-seize compound to the threads of the new sensor (if not pre-applied).
   • Screw in the new oxygen sensor by hand to avoid cross-threading, then tighten it with the socket or wrench to the manufacturer's specified torque (usually around 30 lb-ft).

3. Reconnect Electrical Connections

• Plug in the connector for the new oxygen sensor, ensuring a secure connection.

4. Reconnect Battery

• Reconnect the negative terminal of the battery.

5. Clear Codes and Test

• Use the OBD-II scanner to clear the P0135 code from the ECU.
• Start the engine and allow it to reach operating temperature, then check for any reoccurrence of the code.
