Code P1225 2010 Nissan Pathfinder Description
The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the Engine Control Module (ECM). In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
What are the Possible Causes of the DTC P1225 2010 Nissan Pathfinder?
- Faulty Electric throttle control actuator (TP sensor 2)
- Electric throttle control actuator (TP sensor 2) harness is open or shorted
- Electric throttle control actuator (TP sensor 2) circuit poor electrical connection
How to Fix the DTC P1225 2010 Nissan Pathfinder?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P1225 2010 Nissan Pathfinder Code
1. What does the OBDII code P1225 mean on a 2010 Nissan Pathfinder?
Code P1225 indicates a "Closed Throttle Position Learning Performance Problem," meaning the vehicle’s engine control module (ECM) is detecting an issue with the throttle position sensor's ability to learn and adapt properly.
2. What are the common symptoms of code P1225 in a 2010 Nissan Pathfinder?
Symptoms may include poor throttle response, engine hesitation, stalling, rough idling, and the illumination of the check engine light.
3. What causes the P1225 code to appear on a Nissan Pathfinder?
Common causes include a faulty throttle position sensor (TPS), dirty or malfunctioning throttle body, wiring issues, or a failure in the ECM’s throttle learning process.
4. Can a dirty throttle body trigger code P1225?
Yes, a dirty throttle body can affect the throttle plate’s movement and prevent the ECM from completing the throttle position learning process, triggering this code.
5. How can I fix the P1225 code on my 2010 Nissan Pathfinder?
Cleaning the throttle body, checking for damaged wiring, performing a throttle position reset procedure, or replacing the throttle position sensor may resolve the issue. If the problem persists, consult a professional.
6. Is it safe to drive with the P1225 code active on a 2010 Nissan Pathfinder?
While the vehicle may be drivable, issues like poor throttle response and engine stalling could pose safety risks, so it’s best to address the problem promptly.
7. How do I perform a throttle position reset for the P1225 code?
The throttle position reset typically involves a sequence of ignition key cycles and waiting periods. Refer to the owner's manual or a repair guide for the specific procedure.
8. Can an ECM malfunction cause the P1225 code?
Yes, a malfunctioning ECM may fail to properly learn or store throttle position data, which can lead to this code.
9. Will replacing the throttle position sensor always fix code P1225?
Not necessarily. While the TPS is a common cause, the issue could also stem from the throttle body, wiring, or ECM, so proper diagnosis is essential.
10. Do I need special tools to diagnose or repair code P1225 on a 2010 Nissan Pathfinder?
A basic OBDII scanner can read the code, but diagnosing the root cause may require advanced tools such as a multimeter for checking wiring or a scan tool capable of throttle position resets.
