Featured Pontiac Knock Sensor Models

Satisfaction is something that you get from owning a Pontiac model. Its rare sporting beauty and high performance create driving excitement that you are surely well acquainted of. This is made possible by the premium performance parts which are equipped inside its engine compartment. From the engine to its supporting devices and subsystems, all these work together to attain one end - performance. One of the engine internal parts that work as a safety device for the engine and for your vehicle as a whole is the Pontiac knock sensor.

Engine sensors are numerous in kinds. These input sensors are all connected to the engine control unit for the adjustment or monitoring purposes of the vehicle computer. Some are the mass airflow sensor, oxygen sensor, throttle position sensor, coolant temperature sensor, voltage sensor, manifold absolute pressure sensor, engine speed sensor, and the knock sensor. All these sensors which are injected in the engine fall under the engine's safety and prevention system to attain its peak performance.

Unlike the rest of the sensors that work before and during the engine's four-stroke cycle, the knock sensor starts its duty after the cycle. The Pontiac knock sensor actually sends to the engine computer the result of the compression stroke. Its main function is to sense vibrations and knocks in the cylinder head due to the inaccurate air and fuel mixture. This result is determined after the second cycle, which is the compression stroke in the engine, and then a signal is sent to the engine computer for action.

This device is located at the right side of the engine block, about halfway between the pan and the head, toward the front of the motor. When knocking is found in the engine cylinder, the computer will have to retard the timing in the compression until the signal is back to its reference level. The knock sensor is a performance device that needs to be maintained for it to give accurate report to the engine computer. Any irregularity in its structure, especially in its two ceramic rods, will greatly affect its function and it may need to be changed the soonest.
