Code P1225 2012 Nissan Pathfinder 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 2012 Nissan Pathfinder?
- 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 2012 Nissan Pathfinder?
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 2012 Nissan Pathfinder Code
What does the OBDII code P1225 mean on a 2012 Nissan Pathfinder?
P1225 indicates a "Closed Throttle Position Learning Performance Problem," meaning the throttle body isn't properly learning the closed position during calibration.
What are the common symptoms of code P1225 in a 2012 Nissan Pathfinder?
Common symptoms include poor throttle response, uneven idle, reduced engine performance, and possibly the check engine light illuminating.
What causes code P1225 to appear in a 2012 Nissan Pathfinder?
Causes can include a dirty or malfunctioning throttle body, faulty throttle position sensor, wiring issues, or incomplete throttle position relearning after a repair.
How do I fix the P1225 code on my 2012 Nissan Pathfinder?
Start by cleaning the throttle body, ensuring all connections and wiring are secure, and performing a throttle position relearn procedure. Replacing faulty components like the throttle position sensor may also be necessary.
Can I drive my 2012 Nissan Pathfinder with a P1225 code?
Driving with a P1225 code is possible but not recommended, as it can lead to poor performance, reduced fuel efficiency, and potential long-term damage.
How do I perform a throttle position relearn procedure on a 2012 Nissan Pathfinder?
The procedure usually involves turning the ignition on without starting the engine, waiting for a sequence of seconds, and depressing the accelerator pedal in a specific pattern. Refer to the owner's manual or a repair guide for exact steps.
Will a dirty throttle body always trigger code P1225?
Not always, but a dirty throttle body is a common cause. It can prevent the throttle plate from reaching or learning the proper closed position.
Do I need special tools to diagnose and fix the P1225 code?
A basic OBDII scanner can read and clear the code, but advanced diagnostic tools or professional equipment may be needed for thorough troubleshooting and relearning procedures.
What should I check if cleaning the throttle body doesn’t fix the P1225 code?
If cleaning doesn’t resolve the issue, inspect the throttle position sensor, wiring harness, and connectors for damage, and consider recalibrating or replacing the throttle body.
Can a weak battery cause the P1225 code on a 2012 Nissan Pathfinder?
Yes, a weak or failing battery can disrupt the throttle position relearn process and potentially trigger the P1225 code. Ensure the battery is fully charged and in good condition.
