Where does the knock sensor go?
The knock sensor is located on the outside of the engine block. It is intended to record knocking noise in all engine operating states in order to prevent engine damage. The knock sensor “listens out for” the structure-borne vibrations from the engine block and converts these into electrical voltage signals.
Where is the knock sensor on a Honda Odyssey?
The knock sensor is located in between the left most and center fuel injectors for the front bank (as viewed when standing in front of the engine with the hood up). You will need a torque wrench and some gaskets to do it properly.
What to do if your knock sensor is activated?
To fix- replace sensor or repair the wiring whichever is the issue. Rarely is it the wiring. A knock sensor detects knocking or anything similar from your engine block. If the sensor has activated it may be worth clearing (if possible) with a scanner and hope it’s just a blip.
Can a faulty knock sensor affect gear performance?
Most if not all knock sensor failures are due to no signal from the sensor and so if you put the right gas in the car and you do not hear a pinging then performance will not be affected. Most cars , in particular GM will set a code for a bad sensor but will not illuminate the check engine light.

What do you hear when you knock on a car door?
What you’re hearing is pre-ignition, which occurs when there’s a pocket of fuel/air mixture that’s igniting ahead of the flame front from the spark plug. When this happens, there’s a tiny shockwave that occurs around that explosion (along with the normal detonation from the spark plug), which greatly increases the pressure in the cylinder.
