why would my ecu (0BD2) be throwing a code for the knock sensor???? and how can i fix it???

it's either picking up knock, a bad sensor or unplugged sensor

 

how can i tell if its a bad sensor??? i run 93 octane in a b16b so it shouldn't be detotnating


or

can it be my N1 crank pulley?? because its not harmonically dampered and the knock sensor may be picking up those pulses...im gunna throw the pulley cluster on tomorrow to see if thats the case

 

your knock sensor doesn't thrown a code because it senses a knock....you won't actually know it even does anything! it adjusts your timing whenever it detects a knock, thats all. If your engine light is coming on then the plug isn't connected properly or your sensor is bad. Either way, thats the only two ways that code will come up. Ask me how I know?? I run ODB tests everyday, diagnose ecm problems all day every day.

 

amazing.... im gunna get the engine wire harness schematics and make sure i have the right sensor clip on there then go from there

 

you sure it doesn't throw a code, if that's the case, how come they have a code for knock sensor?
