P1122 GMC 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, ground, and signal circuit.
TP sensor signal voltage should be approximately 0.6 volt at idle. TP sensor voltage should increase to over 4.0 volts at wide open throttle (WOT).

P1122 INFINITI 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 sends voltage signals to the ECM. The ECM determines the current throttle valve opening angle from these signals and controls the throttle control motor to properly adjust the throttle valve opening angle according to driving conditions.

P1122 LAND-ROVER Meaning

The Accelerator Pedal Position (APP) sensor is located in a plastic housing integrated with the accelerator pedal. The housing is injection molded and provides a mounting location for the APP sensor. The sensor is externally mounted on the housing and secured with two Torx screws. The external body of the sensor has a six-pin connector that accepts a connector from the vehicle’s wiring harness.
The sensor has a stud that protrudes into the housing and provides the pivot point for the pedal mechanism. The stud has a slot that allows a pin, which is attached to the sensor’s potentiometers, to rotate approximately 90°, corresponding to the pedal’s movement. The pedal is connected via a linkage to a drum, which engages with the sensor’s pin, converting the pedal’s linear motion into the drum’s rotational motion. The drum is connected to two steel cables. The cables are attached to two tension springs that are secured at the opposite end of the housing. The springs provide a “feel” to the pedal movement and require driver effort similar to a cable-operated throttle. A detent mechanism is located at the front end of the housing and is actuated by a ball located on the drum. At nearly maximum accelerator pedal movement, the ball contacts the detent mechanism. A spring in the mechanism is compressed and gives the driver the sensation of pressing a “kickdown” switch when full pedal travel is reached.

The APP sensor has two potentiometer tracks, each receiving a 5V input voltage from the ECM. Track 1 provides an output of 0.5V with the pedal at rest and 2.0V at 100% full throttle. Track 2 provides an output of 0.5V with the pedal at rest and 4.5V at 100% full throttle. The signals from both tracks are used by the ECM to determine fuel supply for engine operation and also by the ECM and EAT ECU to initiate a kickdown request for the automatic transmission.
The ECM monitors the outputs from each of the potentiometer tracks and can determine the position, rate of change, and direction of the accelerator pedal movement. The “throttle closed” position signal is used by the ECM to initiate idle control and also to interrupt fuel cut-off.
