Knock sensor units detect the engine knocks and monitor the operation within the engine to make sure that the engine is always operating perfectly. It enables your vehicle to obtain the optimum combination of timing and fuel/air mixture to generate power and efficiency. It is
a very important part for your car's fuel efficiency. Knock sensor units are located in the middle of the engine block, near the cylinders. If there is any problem, the knock sensor will send a signal to the PCM (Powertrain Control Module)
or the car computer.
If the knock sensor is not working properly then you will hear sounds releasing from the engine. To maintain the performance of your car you should replace the Knock sensor with a good quality replacement part.
If you don't, it will affect the performance of the car due to the poor quality. At Car Parts Warehouse you can find OEM replacement and aftermarket parts at wholesale price. All
of our car parts are genuine in quality and are tested to meet the industry standards.
