Code P1225 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 P1225 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 P1225 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 P1225 2006 Nissan Maxima Code
1. What does OBDII code P1225 mean on a 2006 Nissan Maxima?
P1225 indicates a "Closed Throttle Position Learning Performance Problem," meaning the engine control module (ECM) has detected an issue with the throttle position learning process.
2. What are common symptoms of P1225 on a 2006 Nissan Maxima?
Symptoms may include poor acceleration, rough idling, reduced fuel efficiency, engine stalling, and the check engine light being illuminated.
3. What causes the P1225 code on a 2006 Nissan Maxima?
Common causes include a dirty or faulty throttle body, a malfunctioning throttle position sensor, wiring or connection issues, or a problem with the ECM.
4. How can I fix the P1225 code on my 2006 Nissan Maxima?
Start by cleaning the throttle body, checking the throttle position sensor and electrical connections, and performing a throttle position learning procedure. If issues persist, further diagnosis may be needed for the ECM.
5. How do I perform a throttle position learning procedure on a 2006 Nissan Maxima?
The procedure involves key cycles and pedal presses in a specific sequence. Consult the service manual for the exact steps or have a professional perform it with a scan tool.
6. Can a dirty throttle body cause the P1225 code?
Yes, carbon buildup in the throttle body can prevent the throttle plate from fully closing, leading to a learning performance issue.
7. Is it safe to drive with the P1225 code on a 2006 Nissan Maxima?
Driving with P1225 may be possible but not recommended, as it can lead to poor engine performance and increased fuel consumption. Address the issue promptly.
8. Will clearing the P1225 code with a scanner fix the problem?
Clearing the code may temporarily turn off the check engine light, but without addressing the underlying issue, the code is likely to return.
9. Can a faulty ECM cause the P1225 code on a 2006 Nissan Maxima?
While rare, a faulty ECM can cause the P1225 code if it fails to properly perform or store the throttle position learning process.
10. How much does it cost to fix a P1225 code on a 2006 Nissan Maxima?
Costs vary depending on the root cause. Cleaning the throttle body is inexpensive, while replacing a throttle position sensor or ECM can be more costly. Expect labor costs if professional diagnosis and repair are needed.
