P0507 2009 Nissan Sentra Code - Idle Control System RPM Higher Than Expected
Quick Answer
The Engine Control Module (ECM) controls the engine idle speed to a specified level through the fine adjustment of the air, which is let into the intake manifold, by operating the electric throttle control actuator. Common causes include Dirty throttle body, Electric throttle control actuator misadjusted or damaged, PCV system. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0507 2009 Nissan Sentra Description
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily. The optimum value stored in the ECM is determined by taking into consideration various engine conditions, such as during warming up, deceleration, and engine load (air conditioner, power steering and cooling fan operation, etc.)
What are the Possible Causes of the DTC P0507 2009 Nissan Sentra?
- Dirty throttle body
- Electric throttle control actuator misadjusted or damaged
- PCV system
- Faulty Electric throttle control actuator
- Intake air leak
- Poor electrical connection to the Intake Air Control (IAC) valve

1. What does the OBDII code P0507 mean for a 2009 Nissan Sentra?
P0507 indicates that the engine's idle speed is higher than the manufacturer’s specified range, suggesting an issue with the Idle Air Control (IAC) system or related components.
2. What are the common symptoms of code P0507 in a 2009 Nissan Sentra?
Symptoms include a noticeably high idle RPM, check engine light illumination, rough idling, and potential stalling when coming to a stop.
3. What causes the P0507 code in a 2009 Nissan Sentra?
Common causes include a dirty or faulty throttle body, vacuum leaks, a malfunctioning Idle Air Control (IAC) valve, or issues with the engine control module (ECM).
4. Can a vacuum leak cause the P0507 code?
Yes, a vacuum leak can allow extra air into the engine, increasing the idle speed and triggering the P0507 code.
5. How can I fix the P0507 code on my 2009 Nissan Sentra?
Inspect and clean the throttle body, check for vacuum leaks, test the Idle Air Control (IAC) valve, and ensure there are no ECM issues. Replace faulty components as needed.
6. Is it safe to drive with the P0507 code on my 2009 Nissan Sentra?
While it may be safe to drive short distances, prolonged driving with this code can lead to engine wear, reduced fuel efficiency, and potential stalling.
7. How do I check for vacuum leaks that might cause the P0507 code?
Inspect hoses, gaskets, and connections for cracks, loose fittings, or damage. You can also use a smoke test or listen for hissing sounds near the engine.
8. Can cleaning the throttle body resolve the P0507 code?
Yes, a dirty throttle body can restrict airflow and result in a higher idle. Cleaning it may resolve the issue if no other problems are present.
9. Do I need to reset the ECM after fixing the P0507 code?
Yes, after repairs, clear the code using a scan tool and allow the ECM to relearn idle settings by following the manufacturer’s instructions.
10. Could a faulty IAC valve trigger the P0507 code?
Yes, a malfunctioning Idle Air Control (IAC) valve can lead to improper idle speed control, causing the P0507 code to appear.
