![]() There is a “button” that rests on a plate and is depressed when the throttle is closed, and when the throttle opens it lifts the plate and the “button” on the sensor releases. My question: could anyone tell me exactly what this sensor is, what it does, and why I really do or don’t need to have it connected? (pics below)įrom what I can infer, it is a very simple (single-pronged connection) sensor that reads whether the throttle is open or not. I haven’t tested it on the road yet as I had dropped insurance on the car for the summer and haven’t reinstated it yet. I turned the car on, and it fired right up and revved when I hit the gas. I stood there staring at it for a few minutes, then said what the hay and just put her all back together again leaving that sensor disconnected. This unkown sensor off the old throttle body was too large to fit in the threading of the new throttle body. I located the sensor it connected to on my old throttle body, removed it, but when I went to install it on the new throttle body I found that the position it was supposed to mount in was occupied by a much smaller allen bolt. Anyway, When I went to reinstall everything, I realized there was an extra electrical connection I hadn’t noticed before. Walker Products 200-1224 Throttle Position SensorI just swapped out the throttle body on my car, not because I needed a new throttle body but because the IAC valve I needed was attached to the throttle body with 4 circle-headed philips screws that didn’t want to budge.Walker Products 200-1225 Throttle Position Sensor.Walker Products 200-1147 Throttle Position Sensor.Walker Products 200-1145 Throttle Position Sensor.As a global manufacturer of emission components, complete quality control is maintained through the manufacturing process from componentry to finished product.
