hi, my timing is retarding on boost so need to check if my ACT sensor and Knock sensor is working correctly. what do i do to check them? want to make sure its not one of these before i replace the ecu.
My knock sensor was actually causing alot of havok . The rolling read out looked like it was drawn on a etcha-sketch!! One way to tell that its playing up.
Maybe put a multimeter across the knock sensor to see if you can short the connector some how to fool the ecu into thinking it has a sensor? Tbh i haven't ever had any problems with knock sensors so haven't taken the time to learn how operate. Know the basics just don't know how many outputs the sensor has etc.
You can leave it plugged in but unscrew it and cable tie it to a rubber hose or somehting in the engine that wont vibrate. The car will run great if it is the knock sensor playing up.
