P0507 2008 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 2008 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.)

Disconnect the battery, remove the intake hose, spray throttle body cleaner on a clean cloth, and gently wipe the throttle plate and bore. Avoid spraying cleaner directly into the throttle body.
8. Could a faulty IAC valve cause P0507 on my 2008 Maxima?
Yes, a malfunctioning IAC valve may fail to regulate the idle speed properly, resulting in higher-than-expected RPMs and triggering the code.
9. Will resetting the ECM clear the P0507 code?
Resetting the ECM may temporarily clear the code, but the underlying issue must be addressed to prevent it from returning.
10. How much does it cost to fix the P0507 code on a Nissan Maxima?
