Code P1225 2011 Nissan Altima Sedan 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 2011 Nissan Altima Sedan?
- 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

Frequently Asked Questions about P1225 2011 Nissan Altima Sedan Code
1. What does OBDII code P1225 mean on a 2011 Nissan Altima Sedan?
P1225 indicates a "Closed Throttle Position Learning Performance Problem," suggesting the throttle body is not correctly learning or adjusting to the closed throttle position.
2. What are the common symptoms of the P1225 code in a 2011 Nissan Altima?
Symptoms may include rough idling, stalling, poor acceleration, decreased fuel efficiency, or the check engine light turning on.
3. What causes the P1225 code to appear in a 2011 Nissan Altima?
Common causes include a dirty or faulty throttle body, issues with the throttle position sensor, a malfunctioning accelerator pedal position sensor, or problems with the electronic control module (ECM).
4. Can a dirty throttle body trigger code P1225?
Yes, a dirty or clogged throttle body can prevent proper throttle position learning, leading to the P1225 code.
5. How do you fix the P1225 code on a 2011 Nissan Altima?
Start by cleaning the throttle body, checking for wiring or sensor issues, and performing a throttle position relearn procedure. If the issue persists, inspect and replace faulty components like the throttle position sensor or ECM.
6. What is a throttle position relearn procedure, and is it necessary for P1225?
A throttle position relearn ensures the ECM correctly registers the closed throttle position. It is often necessary after cleaning or replacing the throttle body or related sensors.
7. Can a bad accelerator pedal position sensor cause the P1225 code?
Yes, a faulty accelerator pedal position sensor can send incorrect signals to the ECM, resulting in a closed throttle position learning problem.
8. Is it safe to drive with the P1225 code on a 2011 Nissan Altima?
Driving with this code may lead to reduced performance or stalling, which can be dangerous. It’s recommended to address the issue promptly.
9. How much does it cost to fix the P1225 code on a 2011 Nissan Altima?
The cost depends on the root cause. Cleaning the throttle body may cost $100-$150, while replacing sensors or the throttle body could range from $200 to $600.
10. Can disconnecting the battery reset the P1225 code?
Disconnecting the battery might temporarily clear the code, but it won’t fix the underlying issue. Proper diagnostics and repairs are required to resolve the problem.
