How to replace the bank 2 knock sensor on 2007 Buick Terraza?

To replace bank 2 Knock Sensor, it will require detaching the right front tire and wheel, then the splash shield. Remove the bank 2 Knock Sensor after disconnecting the engine harness electrical connector from the Knock Sensor and loosening it. When replacing the new bank 2 Knock Sensor 1, do not apply thread sealant since the threads of the sensor are pre-coated at the factory which is very important in detecting detonation properly. Tighten the sensor to 25 nm (18 lb ft) and reconnect the engine harness electrical connector to the Knock Sensor. At last, re-install the splash shield and the right front tire and wheel.
