P0507 2008 Nissan Pathfinder 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 2008 Nissan Pathfinder 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.)

- 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

2. What are common symptoms of code P0507 in a 2008 Nissan Pathfinder?
Symptoms include an engine that idles too high, rough or erratic idle, increased fuel consumption, and the engine light turning on.
3. What causes the P0507 code in a 2008 Nissan Pathfinder?
Common causes include vacuum leaks, a dirty or faulty idle air control valve, throttle body issues, or problems with the ECM.
4. How can I fix the P0507 code in my 2008 Nissan Pathfinder?
Fixes can range from cleaning the throttle body, replacing the idle air control valve, repairing vacuum leaks, to resetting or replacing the ECM.
5. Is it safe to drive my 2008 Nissan Pathfinder with the P0507 code?
While you can drive with this code, it is advisable to address the issue promptly as it can lead to higher fuel consumption and potential long-term engine issues.
6. How do I reset the idle air control system after repairs to clear the P0507 code in a 2008 Nissan Pathfinder?
After repairs, you may need to clear the code with an OBD-II scanner and allow the ECM to relearn the proper idle speed by driving the vehicle or letting it idle for a certain period.
7. Can a faulty battery or charging system cause the P0507 code in a 2008 Nissan Pathfinder?
Yes, if the battery or alternator is failing, it can lead to irregular voltage that disrupts the ECM’s ability to regulate idle speed, potentially setting off the P0507 code.
8. What should I check first when diagnosing the P0507 code in a 2008 Nissan Pathfinder?
First, inspect for any obvious signs of vacuum leaks or damages to the throttle body. Also, check the idle air control valve for operation and cleanliness.
