Pontiac Vibe Knock Sensor

Knock Sensor in Pontiac Vibe is one of the pivotal parts of the car as it include detecting of the engine knock and sends a signal to the powertrain control module to time it. Usually piezoelectric, the sensor translates the pressure, the oscillation to electrical signals for detecting pressure spiky that reflects knock. The sensor assists in controlling ignition timing and maintaining the engine's characteristics and, consequently, it protects against damage resulting from the use of low-octane gasoline. Some can even vary the ignition times for top and bottom Dead-Centres and control boost-pressure for maximum power and durability under varying running conditions. On Pontiac Vibe vehicles, the Knock Sensor is responsible for the overall efficiency of an engine while at the same time defending the car against damaging knock.

Each OEM Pontiac Vibe 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.

    Q: How to replace a knock sensor?
    A: The knock control system is designed in order to lessen spark knock during heavy detonation periods. This gives the engineer an opportunity to make use of optimal spark advances for improved driveability. The output voltage produced by the knock sensor increases as the severity of the knock increases. The PCM monitors the voltage signal, retards ignition timing until detonation ceases. On the front side of engine block, below the cylinder head and mounted on a stud bolt is where knock sensor is located. Remove cable from the negative terminal. Cooling system needs to be drained. Intake manifold should be removed. Disconnect electrical connector and remove fastening nut securing knock sensor and then remove sensor itself. Attach a slight angle at bottom with the connector facing downward in right manner in order to reduce water ingress into it. Fix tightly mounting fastener of a detection device capable of capturing various engine knocking sounds. Do not screw up with your equipment lest something happens to it; over-tightening may cause damage however small it might be that you cannot even see without magnifying glass. Plugin electrical connector, refill cooling system, and look for leaks.
