Code P2122 2011 Nissan Rogue Description
Accelerator pedal position sensor has two sensors. These sensors are a kind of potentiometers which transform the accelerator pedal position into output voltage, and emit the voltage signal to the ECM.
In addition, these sensors detect the opening and closing speed of the accelerator pedal and feed the voltage signals to the ECM. The ECM judges the current opening angle of the accelerator pedal from these signals and controls the throttle control motor based on these signals.
Idle position of the accelerator pedal is determined by the ECM receiving the signal from the accelerator pedal position sensor. The ECM uses this signal for the engine operation
such as fuel cut.
What are the Possible Causes of the DTC P2122 2011 Nissan Rogue?
- Faulty Accelerator Pedal Position Sensor
- Accelerator Pedal Position Sensor harness is open or shorted
- Accelerator Pedal Position Sensor circuit poor electrical connection

2. What are the common symptoms of the P2122 code?
Symptoms may include reduced engine performance, the throttle not responding properly, the Check Engine Light illuminating, or the vehicle entering "limp mode."
3. What causes the P2122 code to appear?
Common causes include a faulty APP sensor, damaged or corroded wiring, loose electrical connections, or issues with the engine control module (ECM).
4. Can I drive my 2011 Nissan Rogue with the P2122 code?
Driving is possible but not recommended, as the vehicle may have limited throttle response or reduced power, potentially posing safety risks.
5. How do I troubleshoot the P2122 code?
Inspect the APP sensor, check the wiring and connectors for damage or corrosion, and use a multimeter to test the sensor’s voltage output.
6. How is the P2122 code typically repaired?
Repairs may include replacing the APP sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming/updating the engine control module (ECM).
7. How much does it cost to fix the P2122 code?
Repair costs vary but typically range from $150 to $400, depending on whether the APP sensor, wiring, or ECM needs replacement or repair.
8. Can a dirty throttle body cause the P2122 code?
While a dirty throttle body can cause performance issues, it’s not a direct cause of the P2122 code, which is specific to the APP sensor circuit.
9. Will clearing the code with a scan tool fix the issue?
Clearing the code may temporarily turn off the Check Engine Light, but the underlying issue must be resolved to prevent the code from returning.
10. How can I prevent the P2122 code from recurring?
Regularly inspect and maintain the accelerator pedal assembly, wiring, and connectors, and address any issues with the APP sensor promptly.
