What should the voltage of the throttle position sensor be?
As the throttle position is critical to engine control, the normal operating output range of the TPS is within some margin of the earth and reference 5 V supply voltages. For example, from around 0.5 V to around 4.5 V.
What is the base voltage of the TP sensor?
Now to be a little more specific, when you crank, start, and get your car moving: The PCM supplies the TP sensor with 5 Volts and Ground. Once the engines starts and is running (idle), the TPS reports a DC Voltage signal of about 0.5V to 0.9V to the PCM. This is the base voltage that the computer needs to have.
Can a potentiometer be combined with a throttle actuator?
Some manufacturers combine the potentiometer with the throttle actuator motor. Whether combined or separate components, their function remain the same. As the throttle position is critical to engine control, the normal operating output range of the TPS is within some margin of the earth and reference 5 V supply voltages.
What is the voltage when the throttle is at idle?
A constant, unbroken, voltage output at around 0.7 V, with the throttle at its idle position. As the throttle moves from its idle position, at around 0.5 s, the output progressively increases with increasing throttle opening. With the throttle at its fully open position, the output is around 3.7 V.
How many volts does a throttle position sensor send?
The throttle position sensor gets 5 Volts and Ground from the ECM. As the engine in your pickup or van idles (and the throttle plate is closed), the throttle position sensor sends the ECM a voltage signal of about 0.9 to 1 Volts.
What are symptoms of bad throttle position sensor?
Here are some specific symptoms you’ll see: TPS diagnostic trouble codes (DTCs) stored in the vehicle’s computer’s memory. Code 23: Throttle Position (TP) Circuit Performance Problem. Really BAD gas mileage. No power as you accelerate the vehicle. Hesitation when you step on the accelerator pedal.
How to test throttle position sensor ( GM 4.3L )?
You can find this tutorial in Spanish here: Cómo Probar El Sensor TPS (1996-2004 GM 4.3L, 5.0L, 5.7L) (at: autotecnico-online.com ). Beside the check engine light (CEL) being on and driving you nuts, your Chevy or GMC pick up (or SUV or van) may be experiencing one or several of the following symptoms:
What are the DTCs for the TPS sensor?
TPS diagnostic trouble codes (DTCs) stored in the vehicle’s computer’s memory. Code 23: Throttle Position (TP) Circuit Performance Problem. Code 53: Throttle Position (TP) Circuit High Input. Code 63: Throttle Position (TP) Circuit Low Input. Code 121: Throttle Position (TP) Circuit Performance Problem.
