• Disconnect the electrical connector and unbolt the sensor from its mounting position.
• Install the new sensor, ensuring it is properly aligned, and tighten to the manufacturer’s specified torque.
• Reconnect the electrical connector.

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and allow it to reach operating temperature.
