Code P1226 2010 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.

- 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

1. What does OBDII code P1226 mean on a 2010 Nissan Altima Sedan?
P1226 indicates a "Closed Throttle Position Learning Performance Problem," meaning the engine control module (ECM) is having trouble learning or recognizing the throttle position when the throttle is fully closed.
2. What are the common symptoms of code P1226 in a 2010 Nissan Altima?
Common symptoms include rough idling, poor acceleration, reduced fuel efficiency, hesitation during throttle response, and illumination of the check engine light.
3. What causes the P1226 code to appear in a 2010 Nissan Altima?
Possible causes include a dirty or faulty throttle body, a malfunctioning throttle position sensor (TPS), damaged wiring or connectors, or a software issue in the ECM.
4. How can I fix the P1226 code on my 2010 Nissan Altima?
Cleaning the throttle body, checking and repairing wiring or connectors, replacing a faulty TPS, or performing a throttle position relearn procedure may resolve the issue.
5. What is a throttle position relearn procedure for a P1226 code?
It is a process where the ECM is reset to relearn the fully closed and fully open positions of the throttle, usually done with a scan tool or following a specific sequence outlined in the vehicle’s manual.
6. Can a dirty throttle body trigger the P1226 code?
Yes, a dirty throttle body can prevent the throttle plate from fully closing or cause incorrect readings, leading to the P1226 code.
7. Is it safe to drive with the P1226 code on a 2010 Nissan Altima?
It may be safe to drive short distances, but the vehicle's performance and fuel efficiency may be affected. Prolonged driving could cause further damage, so it’s best to address the issue promptly.
8. How much does it cost to fix the P1226 code on a 2010 Nissan Altima?
Repair costs depend on the cause but can range from $50-$150 for a throttle body cleaning to $200-$600 if parts like the throttle body or TPS need to be replaced.
9. Can I clear the P1226 code without fixing the problem?
Clearing the code without addressing the underlying issue will only result in it reappearing. Proper diagnosis and repair are necessary to resolve the problem.
10. Can a faulty ECM cause the P1226 code in a 2010 Nissan Altima?
