P2122 DODGE code

P2122 trouble code definition The P2122 OBD-II trouble, or fault, code means that the vehicle’s on-board computer has detected low voltage in the throttle position sensor (TPS), which is usually below 0.17 volts.

What does P2122 mean?

Definition: Throttle/pedal position sensor/switch ‘D’ circuit low. Engine code P2122 indicates your vehicle’s onboard computer system has detected low voltage in your throttle position sensor. The throttle position sensor is used to measure how open the throttle valve is and how much fuel is demanded by your engine.

How much does it cost to fix a throttle pedal position sensor?

An accelerator pedal position sensor on CarParts.com can cost anywhere between $3 and $700. The labor cost for replacing this part typically ranges from $50 to $70.

What causes high voltage in throttle position sensor?

What are the Possible Causes of the P0123 Code? Throttle/Pedal Position sensor circuit issues such as: Loose wiring or connections. Circuit shorted to voltage.

Where is the throttle pedal position sensor located?

A throttle position sensor (TPS) is a sensor used to monitor the air intake of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle.

How do I fix P2122?

What repairs can fix the P2122 code?

  1. Replacing or repositioning a ground wire.
  2. Replacing the wiring and/or connectors in the CAN bus harness or throttle actuator motor.
  3. Replacing the throttle position sensor, the throttle actuator control motor, the throttle position actuator, or the pedal position sensor.

Why does the throttle position sensor Get Low Voltage?

The voltage of the throttle position sensor can drop below the expected range for several reasons, including the following: A loosely-mounted throttle position sensor. Electrical short on the sensor circuit, either to the ground or to another wire. Faulty sensor.

How do you reset the accelerator pedal position sensor?

The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.

How do I test the accelerator pedal position sensor?

Zitat von Youtube: Light to test the accelerator pedal position sensor first purchase a wiring diagram. Online which will help identify the signal voltage reference. And ground wires use the multimeter.

What happens when the accelerator pedal position sensor fails?

If the accelerator pedal sensor fails, the following fault symptoms may occur: Increased engine idling speed. Vehicle does not respond if the accelerator pedal is pressed. Vehicle switches to “limp-home mode”

What is a throttle pedal position sensor switch?

The Throttle Position Sensor/Switch is located on the Throttle Body of the Intake Manifold and the Pedal Position Sensor/Switch is part of the Accelerator Pedal assembly. These sensors provide precise input from the driver’s foot in terms of how MUCH power is needed from the engine and, how URGENTLY power is needed.

What type of sensor is an accelerator pedal position sensor?

In this example, the Accelerator Pedal Position (APP) sensor is of the potentiometer type. It receives two reference voltages from the Powertrain Control Module (PCM), having two ground wires and two signal wires that send a varying voltage back to the PCM relating to accelerator pedal position.
