Knock Sensors - Basics about Knock Sensors

[@Barrys_Workshop]

Great information thanks

[@jf8461]

Can a noisy tappet or lifter trigger the knock sensor?

[@allourdful]

If the knock sensor and wiring test ok what is issue ? I want to know how solve mechanical issues?

[@atomicdmt8763]

excellent. To be clear: the (5V) is sent out as a circuit CHECK only... and the ECU will then receive (~2.5V) signal from the sensor during all other operation? My sensor is a single wire type. THANKS

If the engine and transmission base not ok the knock sensor activate or no way ?

I have a 2013 mazada demio and am not getting any ignition and no start and all the fuse is working.can the knock sensor causes that to happen or the manifold intake?

[@arthurserino2254]

A knock sensor is NOT an accelerometer, that is a completely different device. The knock sensor is a contact microphone that listens for pinging. An accelerometer measures changes in velocity.

If it's not an accelerometer, why are specs in mV/g?
