Product Questions & Answers

Q:what are the knock sensors and what do they do?
john P.
A:BEST ANSWERHi John, A car knock sensor is located on the intake manifold, cylinder, or engine block, it detects preignition and detonation, potentially damaging forms of abnormal combustion. Though full-blown knocking and pinging are audible to the human ear, the knock sensor detects imperceptible levels. A bad knock sensor may also not let the engine accelerate properly while driving on the highway, and cause the vehicle to lose fuel mileage. Show less
