Accelerator Pedal Position Sensor Location, Accelerator Pedal Position Sensor Replacement Cost. But the designs of various car models vary. Step 2: Press the accelerator pedal ALL THE WAY to the floor and hold it for 40 seconds. When you press or let off the gas pedal, it sends that data to the vehicles engine control unit (ECU) to be relayed to the fuel system and throttle body. One hose clamp is located by the MAF sensor, and the other is located by the throttle body. The throttle position sensor is located inside or on the throttle body of the engine. As we already told you, complete failure of this sensor is not possible. Each one has separate signal, Ground, and 5.0 volt reference circuits. Please select a dealer to .
