Code P1226 2006 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 2006 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 2006 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 2006 Nissan Maxima Code
1. What does the OBDII code P1226 mean for a 2006 Nissan Maxima?
P1226 indicates a "Closed Throttle Position Learning Performance Problem," meaning the throttle position sensor (TPS) is not correctly learning or maintaining its closed position.
2. What are the common symptoms of code P1226 in a 2006 Nissan Maxima?
Symptoms include poor acceleration, erratic idling, reduced fuel efficiency, or the throttle not responding properly.
3. What causes the P1226 code to appear in a 2006 Nissan Maxima?
Common causes include a dirty throttle body, a faulty throttle position sensor, wiring issues, or an improperly performed throttle position relearn procedure.
4. How do you fix the P1226 code on a 2006 Nissan Maxima?
Fixes involve cleaning the throttle body, checking and repairing wiring or connectors to the throttle position sensor, or performing a throttle position relearn using a scan tool.
5. Can a dirty throttle body trigger the P1226 code?
Yes, carbon buildup on the throttle body can prevent the throttle plate from closing properly, causing the sensor to misread the closed throttle position.
6. Is it necessary to perform a throttle position relearn for code P1226?
Yes, after cleaning the throttle body or replacing components like the TPS, a throttle position relearn procedure is essential to reset the system.
7. What tools are needed to diagnose and fix the P1226 code?
A diagnostic scan tool, multimeter, and throttle body cleaner are commonly needed to troubleshoot and resolve this issue.
8. Can a failing throttle position sensor cause the P1226 code?
Yes, a malfunctioning TPS can send incorrect signals to the ECM, triggering the P1226 code.
9. What happens if you ignore the P1226 code on a 2006 Nissan Maxima?
Ignoring the code can lead to worsening drivability issues, decreased fuel economy, and possible damage to the throttle body or related components.
10. Is the P1226 code specific to the 2006 Nissan Maxima?
No, while it is common in the 2006 Nissan Maxima, the P1226 code can appear in other vehicles with similar throttle control systems.
