P0507 2004 Nissan Maxima 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, Faulty Electric throttle control actuator. 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 2004 Nissan Maxima 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 2004 Nissan Maxima?
- Dirty throttle body
- 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 2004 Nissan Maxima Code
1. What does the OBDII code P0507 mean on a 2004 Nissan Maxima?
P0507 indicates that the engine control module (ECM) has detected the idle speed is higher than the expected range, which may point to an issue with the idle control system.
2. What are the common symptoms of code P0507 in a 2004 Nissan Maxima?
Symptoms may include an unusually high idle speed, a check engine light, poor fuel economy, and possibly rough or erratic idle behavior.
3. What causes the P0507 code to appear on a 2004 Nissan Maxima?
Common causes include a dirty or faulty throttle body, a vacuum leak, a malfunctioning idle air control valve, or issues with the PCV valve or intake manifold gasket.
4. How can I diagnose the cause of the P0507 code on my 2004 Nissan Maxima?
Start by checking for vacuum leaks, inspecting the throttle body for dirt or carbon buildup, and testing the idle air control valve. A scan tool can also help monitor idle speed data.
5. Can a dirty throttle body trigger the P0507 code on a 2004 Nissan Maxima?
Yes, a dirty throttle body can restrict airflow control, causing the ECM to detect an unusually high idle speed.
6. How do I fix a P0507 code on a 2004 Nissan Maxima?
Cleaning the throttle body, repairing vacuum leaks, replacing a faulty idle air control valve, or addressing intake manifold gasket issues may resolve the problem.
7. Is it safe to drive a 2004 Nissan Maxima with the P0507 code?
While the car may still be drivable, prolonged high idle speeds can lead to increased wear on engine components and reduced fuel efficiency. It's best to address the issue promptly.
8. Can resetting the ECM clear the P0507 code on a 2004 Nissan Maxima?
Resetting the ECM may temporarily clear the code, but if the underlying issue isn't fixed, the code will likely return.
9. What tools are needed to repair the P0507 code on a 2004 Nissan Maxima?
You may need a scan tool, a vacuum tester, basic hand tools, and throttle body cleaner to diagnose and repair the issue.
10. Could a faulty PCV valve cause the P0507 code on a 2004 Nissan Maxima?
Yes, a malfunctioning PCV valve can create a vacuum leak, which may result in a higher-than-expected idle speed and trigger the P0507 code.
