Code P1226 2009 Nissan Rogue 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 P1226 2009 Nissan Rogue?
- 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 P1226 2009 Nissan Rogue?
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 P1226 2009 Nissan Rogue Code
1. What does the OBDII code P1226 mean on a 2009 Nissan Rogue?
P1226 indicates a "Closed Throttle Position Learning Performance Problem," meaning the engine control module (ECM) is having trouble learning or setting the correct closed throttle position for the throttle body.
2. What are the common symptoms of code P1226 in a 2009 Nissan Rogue?
Symptoms may include poor acceleration, rough idling, stalling, reduced fuel efficiency, or the throttle not responding properly to pedal input.
3. What causes the P1226 code on a Nissan Rogue?
Common causes include a dirty or faulty throttle body, a bad throttle position sensor, a malfunctioning accelerator pedal position sensor, or wiring issues like damaged connectors or circuits.
4. How can I fix the P1226 code in my 2009 Nissan Rogue?
Start by cleaning the throttle body, inspecting the throttle position sensor and wiring, and performing a throttle position relearn procedure. Replace faulty components if necessary.
5. What is a throttle position relearn procedure, and why is it important for P1226?
Throttle position relearn resets the ECM's memory of the throttle body's closed position. It's crucial to ensure the ECM can properly control the throttle for optimal engine performance.
6. Can a dirty throttle body cause the P1226 code?
Yes, a dirty throttle body can prevent the throttle plate from closing completely, disrupting the ECM's ability to learn the closed position and triggering the code.
7. Is it safe to drive with the P1226 code active?
Driving with P1226 may be unsafe, as throttle response issues can lead to unpredictable acceleration or stalling, especially in traffic.
8. Do I need to replace the throttle body to fix code P1226?
Not necessarily. Often, cleaning the throttle body and performing a relearn procedure can resolve the issue. Only replace the throttle body if it's confirmed to be defective.
9. How much does it cost to repair a P1226 code on a 2009 Nissan Rogue?
Costs vary, but cleaning the throttle body and performing a relearn procedure may cost $100–$200 at a shop. Replacing the throttle body could cost $300–$600, including parts and labor.
10. Can a faulty accelerator pedal position sensor trigger the P1226 code?
Yes, if the accelerator pedal position sensor isn’t functioning properly, it can send incorrect signals to the ECM, contributing to the P1226 code.
