I have a question. I have a 1999 Tacoma V/6. Has anyone tried to unplug the knock sensors and fool the ECM into thinking they are hooked up. I have been told that a cold engine piston slap is causing my ECM to turn on the SES light. I have checked the circuit and the sensors the way the book says to, and everything seems good. So, before I buy a new ECM or tear the engine down, I was wondering if a resistor could be plugged into the line going to the ECM making it think the sensors are plugged in. If so, what size resistor should I try?
