P0507 2007 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 2007 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.)
What are the Possible Causes of the DTC P0507 2007 Nissan Pathfinder?
- 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
How to Fix the DTC P0507 2007 Nissan Pathfinder?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0507 2007 Nissan Pathfinder Code
1. What does the OBDII code P0507 mean for a 2007 Nissan Pathfinder?
P0507 indicates that the idle control system is maintaining the engine's RPM higher than the expected range, often signaling an issue with the idle air control system or related components.
2. What are the common symptoms of code P0507 in a 2007 Nissan Pathfinder?
Symptoms include a higher-than-normal idle speed, rough idle, potential stalling, and the Check Engine Light turning on.
3. What are the potential causes of code P0507 in a 2007 Nissan Pathfinder?
Possible causes include a dirty or faulty throttle body, vacuum leaks, a malfunctioning idle air control valve, PCV system issues, or an incorrect engine control module (ECM) program.
4. Can a vacuum leak cause the P0507 code to appear?
Yes, vacuum leaks are a common cause of this code, as they can disrupt the engine's air-to-fuel ratio and lead to higher idle RPMs.
5. How do you troubleshoot code P0507 in a 2007 Nissan Pathfinder?
Start by checking for vacuum leaks, inspecting the throttle body for carbon buildup, testing the idle air control valve, and ensuring the ECM has the latest software updates.
6. Can a dirty throttle body trigger the P0507 code?
Yes, carbon buildup on the throttle body can restrict airflow and cause the idle control system to compensate, leading to higher RPMs and triggering the code.
7. How can I fix code P0507 on my 2007 Nissan Pathfinder?
Possible fixes include cleaning the throttle body, repairing vacuum leaks, replacing the idle air control valve if faulty, and ensuring the ECM is properly programmed.
8. Is it safe to drive with the P0507 code on a 2007 Nissan Pathfinder?
While it may be safe to drive for short distances, ignoring the code can lead to further engine performance issues, so it’s best to address it promptly.
9. How much does it cost to fix code P0507 on a 2007 Nissan Pathfinder?
Costs vary depending on the issue, ranging from $50 for a throttle body cleaning to $500 or more for replacing parts like the idle air control valve or repairing vacuum leaks.
10. Can resetting the ECM clear the P0507 code?
Resetting the ECM may temporarily clear the code, but the underlying issue must be resolved to prevent the code from returning.
