  • Expert Hi,
    Sesors used in cars is a mechetronic device meaning combination of mechanical and electronic mechanism. The sensor malfunction can be due to malfunctioning of convesion of mechanical or electronic part of the sensor .Thorough inspection of sensor has to be done for the exact cause of failure.Remidy is to diagnosie the failed sensor using diagostic kit and replaces the particular sensor.This canbe done at authorised service center.

  • Dear mr.reddy,
    Knock sensors are fed in the pcm of the car which detect abnormal vibrations in the engine, it also helps to produce ac voltage which in turn increases the vibrations in an engine. I would suggest you to kindly get it verified and diagnosed from an authorised service station.

  • I have been in the car trade [repairs] for more than forty years. I would like to know how Mr.Ramangireddy Gazzala came to the conclusion that 'knock sensor' is faulty? there are many reasons for an engine 'knocking'Instead of going to any 'agent' most of whom do not have the equipment nor the personnel to diaognise faults, go to a private garage who has a good reputation, and your problem will be solved.
