Code P0122 2007 Nissan Pathfinder Description

The Throttle Pedal Position (TPP) responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module (ECM). In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the ECM.
Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the Wide open and closed throttle position switch, which is built into the throttle position sensor unit, is not used for engine control.

Frequently Asked Questions about P0122 2007 Nissan Pathfinder Code

1. What does the OBDII code P0122 mean on a 2007 Nissan Pathfinder?

P0122 indicates that the Throttle Position Sensor (TPS) "1" circuit has a voltage input that is lower than the expected range, signaling a potential issue with the TPS or its wiring.

2. What are the common symptoms of code P0122 in a 2007 Nissan Pathfinder?

Symptoms may include poor acceleration, reduced engine performance, stalling, hesitation, and the check engine light being illuminated.

3. What causes the P0122 code on a 2007 Nissan Pathfinder?

Common causes include a faulty throttle position sensor, damaged or corroded wiring, a loose electrical connection, or a malfunctioning engine control module (ECM).

4. How do I diagnose the P0122 code on my 2007 Nissan Pathfinder?

Start by using an OBDII scanner to confirm the code, inspect the TPS and its wiring for damage or corrosion, and measure the TPS voltage with a multimeter to ensure it's within the specified range.

5. Can I drive my 2007 Nissan Pathfinder with a P0122 code?

Driving with a P0122 code is not recommended, as it can cause reduced engine performance and potentially lead to unsafe driving conditions.

6. How can I fix the P0122 code on a 2007 Nissan Pathfinder?

Repairs may involve replacing the throttle position sensor, repairing or replacing damaged wiring, cleaning electrical connections, or reprogramming the ECM if necessary.

7. How much does it cost to fix a P0122 code on a 2007 Nissan Pathfinder?

The cost can vary, but replacing the TPS typically costs $100-$300, including parts and labor. Additional repairs for wiring or ECM issues may increase the cost.

8. Can a dirty throttle body cause the P0122 code in a 2007 Nissan Pathfinder?

While not a direct cause, a dirty throttle body can lead to improper TPS readings, which might trigger the P0122 code. Cleaning the throttle body may help if it's contributing to the issue.

9. Does the P0122 code always mean the throttle position sensor is bad?

No, the code could also result from wiring issues, poor electrical connections, or a malfunctioning ECM, so proper diagnosis is important before replacing parts.

10. Will a hard reset of the ECM clear the P0122 code on a 2007 Nissan Pathfinder?

Clearing the code with an OBDII scanner or resetting the ECM may temporarily erase it, but if the underlying issue isn't fixed, the code will likely return.
