Code P1226 2004 Nissan Maxima 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 2004 Nissan Maxima?
- 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 2004 Nissan Maxima?
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 2004 Nissan Maxima Code
1. What does the OBDII code P1226 mean for a 2004 Nissan Maxima?
P1226 indicates a "Closed Throttle Position Learning Performance Problem," meaning the throttle body is not properly learning or retaining its closed position setting.
2. What are common symptoms of the P1226 code on a 2004 Nissan Maxima?
Symptoms may include rough idling, reduced throttle response, stalling, and the check engine light turning on.
3. What causes the P1226 code to occur?
Common causes include a dirty or faulty throttle body, issues with the throttle position sensor (TPS), wiring or connector problems, or a failed throttle control actuator.
4. Can a dirty throttle body trigger the P1226 code?
Yes, a dirty throttle body can prevent the system from accurately learning the closed throttle position, triggering the P1226 code.
5. How can I fix the P1226 code on my Nissan Maxima?
Cleaning the throttle body, ensuring proper connections, and performing a throttle position relearn procedure can often resolve the issue. If the problem persists, replacement of the throttle body or TPS may be necessary.
6. Do I need special tools to resolve the P1226 code?
You may need a scan tool capable of performing a throttle position relearn procedure and basic tools for cleaning or inspecting the throttle body.
7. What is a throttle position relearn procedure?
The throttle position relearn procedure resets the throttle body’s memory so it can properly learn the closed and open throttle positions. This can often be done with a scan tool or by following a specific manual process.
8. Can I drive my car with the P1226 code?
Driving with the P1226 code is possible but not recommended, as it can lead to poor engine performance, stalling, or reduced fuel efficiency.
9. Is the throttle position sensor the same as the throttle body?
No, the throttle position sensor (TPS) is a component of the throttle body that monitors its position. A malfunctioning TPS can lead to the P1226 code.
10. How much does it cost to repair the P1226 code on a 2004 Nissan Maxima?
The cost depends on the cause. Cleaning the throttle body may cost $50–$100, while replacing the throttle body or TPS can range from $300 to $800, including labor.
