Where is the knock sensor located, and How to its removal and installation on Pontiac G6?

The knock sensor for the four-cylinder models is located on the block just beside the starter motor. Start with raising the front side of the car and then placing it on stands that will help in holding it up. Remove the knock sensor wiring harness which is connected to the dipstick tube, unscrew the dipstick tube and take it out. Then ,you have to unscrew the electrical connector from knock sensor, unscrew the sensor retaining bolt and pull out the sensor. Installation is done in reverse order to removal while tightening of the mounting bolt is done to the required torque. On the V6 models, there are two knock sensors on the front side of the block, in the upper middle position, and close to the exhaust manifolds, thus they are of difficult access and require the car to be lifted. Jack up the vehicle and make certain it is supported firmly on jackstabs. If employed in the working on the rear sensor of 3.6L V6 engine, then you should take off the lower heat shield of the exhaust manifold. Disconnect the electrical connector from the sensor, then remove the nut and bolt, and the sensor. Just as with the four-cylinder models, installation is the reverse of removal, tightening of the mounting bolt to the correct torque is the last step.

Pontiac G6 Knock Sensor

Pontiac G6 has a Knock Sensor as part of its working functionality of the car for determining knock that happens with ignition timing. This sensor relays information to the vehicle's PCM which will allow the PCM to alter ignition timing to reduce explosive forces. Normally the Pontiac G6 knock sensor is piezoelectric in nature, which means that it changes mechanical vibrations into electrical signals that are then checked for pressure spikes which signify knocking. Year in year out the Pontiac G6 model rely on the latest knock sensor that enable it to fine tune ignition interval even in the changing fuel quality and other conditions. This capability helps to maximize the engines' performance when using low octane fuels and at the same time, reduce chances of damaging the engine. This is mainly because of the evaluation and regulating features of the Pontiac G6 Knock Sensor that enhances the performance and durability of the car.

Each OEM Pontiac G6 Knock Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
