P2122: Faulty Throttle Position Sensor Triggers Check Engine Light. The automobile fault code P2122 can be caused by a faulty APP sensor, open or shorted harness, poor electrical connection, or a faulty PCM.

A P2122 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 - 0.20 volts (V). The "D" refers to a particular circuit, sensor, or area of a particular circuit.

The P2122 diagnostic trouble code indicates an issue with the throttle/pedal position sensor/switch 'D' circuit being lower than the expected voltage range. This sensor is crucial for the proper functioning of the electronic throttle control system, which regulates the engine's air intake based on driver input.

What Is the P2122 Code? Can I Still Drive? The P2122 code indicates that the powertrain control network (PCM) has detected an issue with the throttle position sensor (TPS), specifically...

2023年12月24日 · Code P2122 is like your car telling you it’s having trouble understanding how much you’re pressing the gas pedal. This code pops up when there’s something wrong with the electrical parts that tell your car’s computer about your gas pedal’s position.

2024年5月11日 · What causes the OBDII code P2122 in a Dodge related to the Throttle/Pedal Position Sensor/Switch 'D' Circuit Low? - The code is typically triggered by a malfunction in the throttle position sensor or its circuit, such as a faulty sensor, damaged wiring, or …

2018年3月8日 · OBD II fault code P2122 is a generic code that is defined as “Throttle/Pedal Position Sensor/Switch “D” Circuit Low”, and is set when the PCM (Powertrain Control Module) detects an abnormally low input voltage from the sensor, switch, or circuit in the throttle control system that is labelled “D”.

2018年10月24日 · P2122, P2127 code - The Electronic Throttle Control (ETC) system uses two Accelerator Pedal Position (APP) Sensors to monitor the accelerator pedal position. The APP sensors 1 and 2 are integrated into one assembly located at the pedal assembly.

2020年6月14日 · Code P2122 Description The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module (PCM) and used to determine the amount of torque requested by the operator. There are 2 pedal position signals in the sensor.

P2122 is a diagnostic trouble code (DTC) for "Throttle Position Sensor/Switch A Circuit Low Input". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
