Code 24 throttle position sensor voltage low or throttle position sensor voltage high.
If the voltage measured exceeds the voltmeter range then the voltmeter needle remains in it's maximum position until it's voltage values are considerably reduced.
A voltmeter measures voltage in volts.
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.
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.
Voltage is measured with a voltmeter.
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.
No.
no
Use a voltmeter with a high input impedance and measure at the source the voltage.
A potentiometer is a variable resistor, while a voltmeter is a device that measures voltage.
