P1120 PONTIAC Meaning

The Throttle Position (TP) sensor is a potentiometer. The TP sensor provides a voltage signal that changes relative to the throttle blade angle. This signal voltage is one of the most important inputs used by the Powertrain Control Module (PCM). The TP sensor has a 5.0-volt reference, a ground, and a signal circuit.
The TP sensor signal voltage should be approximately 0.6 volts at idle. The TP sensor voltage should increase to over 4.0 volts at wide open throttle (WOT).

P1120 TOYOTA Meaning

The accelerator pedal position sensor is mounted on the throttle body and has 2 sensors to detect the accelerator position and accelerator position malfunction.
The accelerator pedal position sensor is connected to the accelerator pedal by the accelerator cable and the voltage applied across the VPA and VPA2 terminals of the engine control module (ECM) changes between 0 V and 5 V proportionally to the accelerator pedal opening angle.

The ECM evaluates the current accelerator pedal opening angle from the input of these signals from the VPA and VPA2 terminals and the ECM controls the throttle motor based on these signals.
If code P1120 is stored, the ECM cuts power to the throttle motor and magnetic clutch, and the throttle valve is completely closed by the return spring.
However, the throttle valve opening angle can be controlled by the accelerator pedal via the accelerator cable

P1121 Meaning

The electronic throttle control actuator consists of a throttle control motor, throttle position sensor (TPS), etc. The throttle control motor is operated by the Engine Control Module (ECM) and it opens and closes the throttle valve.

The throttle position sensor detects the throttle valve position and the opening/closing speed of the throttle valve and transmits voltage signals to the ECM. The ECM evaluates the current throttle opening angle from these signals and the ECM controls the throttle control motor to properly adjust the throttle opening angle in response to driving conditions.
