TPS sensor issue

Post by Yves »

I have wired up my TPS sensor, but without moving the throttle the laptop is indicating 100% throttle position. What could be wrong here ?

OK.... what does the gauge do when you open the throttle?

Who's sensor is this (brand)? Exactly how do you have the sensor connected?
