P0507 2002 Nissan Sentra 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 2002 Nissan Sentra 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 2002 Nissan Sentra?
- 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 2002 Nissan Sentra Code
1. What does the OBDII Code P0507 mean on a 2002 Nissan Sentra?
- Code P0507 indicates that the Idle Control System RPM is higher than expected. This means the engine is idling at a higher RPM than the vehicle's computer has been set to maintain.
2. What are common symptoms of code P0507 in a 2002 Nissan Sentra?
- Symptoms include a higher than normal idle speed, rough or erratic idle, the engine stalling at idle, increased fuel consumption, and possibly the Check Engine Light turning on.
3. What causes the OBDII Code P0507 to appear on my 2002 Nissan Sentra?
- Common causes include vacuum leaks, a dirty or faulty idle air control valve (IACV), throttle body issues, or problems with the PCV valve or system.
4. How can I fix the high idle issue indicated by code P0507 on my 2002 Nissan Sentra?
- To fix this issue, inspect for vacuum leaks and repair any found. Clean or replace the idle air control valve if necessary, and ensure the throttle body is clean and functioning properly. Also, check the PCV valve and replace it if it's faulty.
5. Is it safe to drive my 2002 Nissan Sentra with the P0507 code?
- While it may be safe to drive for a short distance, driving with a high idle condition can lead to other issues, such as increased wear on the engine or potential safety risks due to erratic engine behavior. It's best to address the issue promptly.
6. How can I diagnose the exact cause of code P0507 on my 2002 Nissan Sentra?
- Begin by checking for vacuum leaks using a smoke machine or by visually inspecting all vacuum hoses and connections. Test the idle air control valve and throttle body for proper operation. A professional scan tool can also help in monitoring idle RPM and other engine parameters.
7. Can a dirty throttle body cause the P0507 code on a 2002 Nissan Sentra?
- Yes, a dirty throttle body can cause air flow issues, leading to an incorrect air-fuel mixture and higher idle speeds, which triggers the P0507 code. Cleaning the throttle body might resolve the issue.
8. What tools are required to diagnose and fix the P0507 code on a 2002 Nissan Sentra?
- Basic hand tools, a digital multimeter, a vacuum gauge or smoke machine for detecting leaks, and a professional OBDII scanner are useful for diagnosing and repairing issues related to this code.
9. How often does the idle air control valve need to be replaced to avoid issues like P0507?
- The idle air control valve does not have a specific replacement schedule, but it should be inspected regularly and cleaned or replaced as needed, especially if symptoms of a failing IACV, like erratic idle or engine stalling, are noticed.
10. After fixing the P0507 code in my 2002 Nissan Sentra, the Check Engine Light is still on. What should I do?
- After repairs, if the Check Engine Light remains on, use an OBDII scanner to clear the code. If the light returns, further diagnostics are needed as there may be additional issues or the initial repair may not have fully resolved the problem.
