Throttle Position (TP) Sensor

NOTE: TP sensor is not adjustable. For further testing procedures, perform TP sensor related diagnostic test. See appropriate SELF-DIAGNOSTICS article.

NOTE: Throttle control is electronic with NO mechanical link from engine to accelerator pedal. The PCM and Throttle Actuator Control (TAC) module monitors the position of accelerator pedal based on signals from a nonadjustable Accelerator Pedal Position (APP) sensor. The APP sensor is mounted above accelerator pedal.

TP SENSOR VOLTAGE SPECIFICATIONS

Application

⁽¹⁾ Volts

5.7L

⁽²⁾

⁽¹⁾	Voltage range is from idle to wide open throttle.

⁽²⁾	TP sensor is 2 individual units within one housing. TP sensor 1 signal voltage ranges from one volt with throttle closed to more than 3.5 volts at wide open throttle. TP sensor 2 signal voltage ranges from about 3.8 volts with throttle closed to less than one volt at wide open throttle.
