  • Q:

    can the knock sensor make my car stall
    Asked on 8/8/2012 by jeff from toms river nj

    1 answer



      The knock sensor in a car engine determines if the pressure resulting from the fuel to air ratio in the engine is optimal for best performance. If the fuel mix isn't correct, the cylinders can be exploding with too much force and cause an engine knock, which can damage the engine and result in costly repairs. The knock sensor is very vibration-sensitive and can malfunction. If the sensor starts to fail, there are several symptoms to look for. Sluggish engine, slow acceleration, poor fuel economy are some of the symptoms.
