Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the battery to ensure safety while working on the electrical system.
2. Inspect and Replace the Oxygen Sensor

  1. Locate the Upstream Oxygen Sensor:

    • The upstream oxygen sensor is located in the exhaust manifold before the catalytic converter.

  2. Remove the Oxygen Sensor:

    • Use an oxygen sensor socket or a 22mm wrench to carefully unscrew the sensor from the exhaust manifold.
    • Be cautious of any exhaust heat and wear protective gloves.

  3. Install New Oxygen Sensor:

    • Apply anti-seize compound on the threads of the new oxygen sensor (if not pre-applied).
    • Screw the new sensor into the exhaust manifold and tighten it to the manufacturer's specified torque (typically around 30 lb-ft).
3. Reconnect Electrical Connections

  1. Connect the Sensor Wiring:

    • Plug in the wiring harness connector to the new oxygen sensor, ensuring a secure fit.

  2. Inspect the Wiring:

    • Before reconnecting, double-check that there are no damaged wires or connectors.
4. Reconnect Battery and Clear Codes

  1. Reconnect the Battery:

    • Reconnect the negative terminal of the battery.

  2. Clear Engine Codes:

    • Use the OBD-II scanner to clear the P0135 code from the vehicle's computer.
