I am getting a code 23 from my ECU and the car is running kinda poorly. I am wondering how I check the Knock sensor to find out if it is malfunctioning or what. I’ll prolly just end up chipping my ecu anyway to bypass the knock sensor all to gether, but I wanna know if the problem is the sensor itself, or if maybe it is actually detecting a problem. Thanks in advance for your help.
here’s a thought. is it possible that my timing is off which is making the knock sensor throw a code? should I get a timing gun? how do I check the knock sensor to see if it is bad?
check the timing first. If the timing is ok then check the knock sensor wire and then the ECU pin to make sure that it is making good contact. If those two do not solve the problem then try replacing the knock sensor.
