- Follow specific replacement procedures for the failed component.
- Example: For oxygen sensor replacement:
  1. Disconnect the battery.
  2. Locate the oxygen sensor (usually near the exhaust manifold).
  3. Unplug the sensor connector.
  4. Use an O2 sensor socket to remove the old sensor.
  5. Install the new sensor and torque to manufacturer specifications.
  6. Reconnect the sensor and battery.
