the voltage "persay" comes from the ecu(computer) i would not use a test light to see if voltage is present thay can be intrusive and short the ecu u will need a dvom meter and service manual to test that circut
Code 24 throttle position sensor voltage low or throttle position sensor voltage high.
The Throttle Sensor responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the Throttle Valve position into output voltage, and emits the voltage signal to the ECU. In addition, the sensor detects the opening and closing speed of the Throttle Valve and feeds the voltage signal to the ECU.
Output voltage will be .5v to 4.5v
A Throttle Position Sensor (TPS) reports to the ECM how open the throttle is. The signal is sent as voltage to the ECM, and the amount of voltage reports how open the throttle is. The throttle is what allows gasoline to get to the engine, and in a car that is the gas pedal. We would think fo the value as 0% to 100% and any range between.
According to my factory service manual the voltage at the throttle position sensor should vary from about 0.5 volts in the idle position to 5.0 volts in the wide open throttle position.
The throttle position sensor is in the throttle body.
Throttle Position Sensor(TPS)/Accelerator Pedal Position Sensor(APPS) signal voltage high.
The function of a throttle position sensor is to monitor the position of the throttle in an internal combustion engine.
Intake Throttle Position Sensor High Voltage
The throttle position sensor is located on the throttle body at the end of the throttle shaft.
The throttle position sensor is located on the throttle plate.
The throttle position sensor is on the throttle body.
