can be a sensor but also may be lower end damage ---https://oards.com/knock-sensor-symptoms-and-replacement-cost/

An explanation of the cause of the code and repair suggestions can be found at the link below.
As a matter of interest, the knock sensor is virtually a microphone and can be of a few types. A capacitor type cannot be tested with an average multimeter as there is normally no physical continuity and if in doubt, replacement would seem the best option.

You need to have it diagnosed first , may not even be a bad knock sensor . Would hate to see you spend money needlessly ! An your vehicle has two knock sensors bank 1 an bank 2 .What DTC ?

Hi, it could be a wiring issue. I would check for a broken connection or bare wire shorting to ground. Usually though, when the computer loses the knock sensor signal, it will ****** the timing to a safe range that will not allow the engine to knock. If you tell me which engine you have, I can give you more specific troubleshooting steps, such as the reference voltage for the circuit.

I think you mean the MAF Sensor...average cost is $35-$45...your parts store can also help you with the location...:) Hope this helps.

It is where the dashed circle is at the end of the line...

knock sensor is on the block, easy to do. not sure exactly where it is on your specific car but it looks like a fat bolt with 2 wires running out of it. but also check the wiring if its good for the knock sensor

Well, it could be either and oxygen sensor or a knock sensor.

Oxygen sensor monitors O2 levels in the exhaust.

The knock sensor listens for engine pinging and adjusts the timing as needed.

Prices vary on repair. I would recommend having the owner of the car either show you something from a repair shop that has the sensor name written, or take the car to a parts store that offers free code scanning and see what comes up.

What i did is remove the check engine bulb coz even if you change the knock sensor the light will still go on coz our engine is a bit old.
