P2122 2006 Ford Fusion Code - Throttle/Pedal Position Sensor/Switch 'D' Circuit Low

Quick Answer

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. Common causes include Faulty Accelerator Pedal Position (APP) Sensor, Accelerator Pedal Position (APP) Sensor harness is open or shorted, Accelerator Pedal Position (APP) Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2122 2006 Ford Fusion 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. Both signals, APP and APP2, have a positive slope (increasing angle, increasing voltage), but are offset and increase at different rates. The 2 pedal position signals make sure the PCM receives a correct input even if 1 signal has a concern. The PCM determines if a signal is incorrect by calculating where it should be, inferred from the other signals. If a concern is present with one of the circuits the other input is used. There are 2 reference voltage circuits, 2 signal return circuits, and 2 signal circuits (a total of 6 circuits and pins) between the PCM and the APP sensor assembly. The pedal position signal is converted to pedal travel degrees (rotary angle) by the PCM. The software converts these degrees to counts, which is the input to the torque based strategy. The P2122 code sets when The accelerator pedal position (APP) sensor 1 is out of self-test range low.

Frequently Asked Questions about P2122 2006 Ford Fusion Code

1. What are the common symptoms of OBDII code P2122 in a 2006 Ford Fusion?

When the Throttle/Pedal Position Sensor/Switch 'D' Circuit Low error code P2122 occurs, you may experience reduced engine power, hesitation or surging during acceleration, and the vehicle may go into limp mode.

2. What are the possible causes of OBDII code P2122 in a 2006 Ford Fusion?

The code P2122 in a 2006 Ford Fusion is commonly caused by a faulty throttle position sensor, damaged wiring or connectors in the throttle pedal position sensor circuit, or a problem with the engine control module (ECM).

3. How can I diagnose the Throttle/Pedal Position Sensor/Switch 'D' Circuit Low error code in a 2006 Ford Fusion?

Diagnosing the P2122 code involves using a scan tool to check for the code, testing the throttle position sensor's voltage output, inspecting the wiring and connectors for damage, and checking the ECM for any faults.

4. Can I drive my 2006 Ford Fusion with OBDII code P2122?

While it may be possible to drive with the P2122 code present, it is not recommended as it can lead to further damage to the vehicle. It is best to address the issue promptly to prevent potential safety hazards.

5. How do I repair OBDII code P2122 in a 2006 Ford Fusion?

To repair the Throttle/Pedal Position Sensor/Switch 'D' Circuit Low code, you may need to replace the faulty throttle position sensor, repair any damaged wiring or connectors, or reprogram the ECM. It is advisable to seek professional help for accurate diagnosis and repair.

6. Can a dirty throttle body cause the P2122 error code in a 2006 Ford Fusion?

While a dirty throttle body can cause related issues, such as rough idle or poor acceleration, it is unlikely to directly trigger the P2122 code. Focus on checking the throttle position sensor and related components first.

7. How much does it cost to fix OBDII code P2122 in a 2006 Ford Fusion?
