P0507 2003 Nissan Altima Sedan 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, PCV system, Electric throttle control actuator misadjusted or damaged. 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 2003 Nissan Altima Sedan 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 2003 Nissan Altima Sedan?
- Dirty throttle body
- PCV system
- Electric throttle control actuator misadjusted or damaged
- Faulty Electric throttle control actuator
- Intake air leak
- Poor electrical connection to the Intake Air Control (IAC) valve

Frequently Asked Questions about P0507 2003 Nissan Altima Sedan Code
1. What does the P0507 code mean on a 2003 Nissan Altima Sedan?
The P0507 code indicates that the engine's idle speed is higher than the manufacturer’s specified range, suggesting an issue with the idle control system.
2. What are the common symptoms of the P0507 code in a 2003 Nissan Altima?
Symptoms include a high idle speed, rough idling, engine stalling, poor fuel efficiency, and possible illumination of the check engine light.
3. What causes a P0507 code on a 2003 Nissan Altima?
Common causes include a dirty or faulty throttle body, vacuum leaks, a malfunctioning IAC (Idle Air Control) valve, or issues with the PCV valve or intake manifold gasket.
4. How can I diagnose the P0507 code in my 2003 Nissan Altima?
Diagnosis typically involves inspecting for vacuum leaks, cleaning the throttle body, testing the IAC valve, and checking for proper connections in the intake system.
5. Can a dirty throttle body cause a P0507 code?
Yes, a dirty throttle body can disrupt airflow and lead to higher-than-normal idle speeds, triggering the P0507 code.
6. Is it safe to drive with the P0507 code on a 2003 Nissan Altima?
While the car may still be drivable, ignoring the code can lead to further engine issues, reduced fuel efficiency, and potential stalling problems.

Common fixes include cleaning or replacing the throttle body, repairing vacuum leaks, replacing the IAC valve, or recalibrating the idle speed with a scan tool.
8. Can a vacuum leak trigger the P0507 code?
Yes, vacuum leaks can allow excess air into the intake, increasing idle RPM beyond the expected range and causing the P0507 code.
9. Do I need to reset the ECU after fixing the P0507 code?
Yes, after making repairs, it’s recommended to clear the code with an OBDII scanner and allow the ECU to relearn the proper idle settings.
10. How much does it cost to fix the P0507 code on a 2003 Nissan Altima?

I did the relearn on my 2003 nissan altima v6 se and it works for a while and then goes back to the same thing i even got a new throttle body and did it work good for like 10 min of driving and then rpms start acting up again what do indo any advice
-
I haven't had that problem before, but I checked a national database of repairs for your model and year. If the problem persist after replacing the Throttle Body and performing the relearn procedure, the most likely cause of the problem is the Positive Crankcase Ventilation (PCV) Valve and/or reprogramming the ECM.

I when i took it to the mechanic he said he did the relearn and said i have a cylinder misfire and i changed the pcv just to be safe . Im a take it to the nissan dealership to get a diagnostic test done
