How many wires does a TP sensors have?
How many wires does a TP sensors have?
The throttle position sensor (TPS) is a potentiometer located on the throttle body and attached to the throttle plate opposite the throttle linkage. It has three wires: battery voltage, 5-volt reference, and a signal wire.
What should the base voltage be for the throttle position sensor?
Once the car or truck starts and is idling and since the throttle is closed, the TPS sends a base throttle position signal of about 0.5 to 0.9 Volts to the PCM on the Blue wire (this voltage will vary slightly on your vehicle but should be within the 0.5 to 0.9 Volts DC).
Where is the TPS signal supplied to the ECM?
The TPS voltage signal is supplied to the VTA terminal. A ground wire from the TPS to the E2 terminal of the ECM completes the circuit. At idle, voltage is approximately 0.6 – 0.9 volts on the signal wire. From this voltage, the ECM knows the throttle plate is closed.
What are the symptoms of a failing TPS sensor?
One of the most common symptoms of a failing TPS would be a tip-in hesitation or stumble when you apply throttle to take off from a stop. This can be caused by a dead spot in the TP sensor’s internal circuitry, which usually causes the output voltage signal to not change (or it drops out) when the throttle opens.
How does the ETCS-i throttle position sensor work?
At this point, the ECM measures 0 volts and there is 0 volts at the IDL terminal. When the throttle is opened, the switch opens and the ECM reads +B voltage at the IDL circuit. The TPS on the ETCS-i system has two contact arms and to resistors in one housing. The first signal line is VTA1 and the second signal line is VTA2.

Do you need to calibrate the 1988-1992 TPS sensor?
TIP 2: Since the1988-1992 TP sensors are the adjustable type, these need to be calibrated to a certain output Voltage (when they’re replaced with a new one). If this is the case in your vehicle, please read section: How To Calibrate the 1988-1992 TPS.
