P0507 2008 Nissan Altima Sedan 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 Altima Sedan 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 2008 Nissan Altima Sedan?
- 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 2008 Nissan Altima Sedan?
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 2008 Nissan Altima Sedan Code
1. What does the OBDII code P0507 mean for a 2008 Nissan Altima Sedan?
The P0507 code indicates that the Idle Control System RPM is higher than expected, meaning the engine idle speed is above the manufacturer’s specified range.
2. What are the common symptoms of a P0507 code in a 2008 Nissan Altima?
Symptoms include high or fluctuating idle speed, increased engine noise at idle, poor fuel economy, and potential stalling when coming to a stop.
3. What causes the P0507 code to appear on a 2008 Nissan Altima?
Common causes include a dirty or faulty throttle body, vacuum leaks, issues with the idle air control valve, or a malfunctioning mass airflow (MAF) sensor.
4. Can a dirty throttle body trigger the P0507 code?
Yes, a dirty or carbon-clogged throttle body can cause the idle speed to increase, triggering the P0507 code.
5. How can vacuum leaks cause the P0507 code?
Vacuum leaks allow extra air into the intake system, causing the engine control module (ECM) to detect higher-than-expected idle RPM.
6. Can a failing mass airflow (MAF) sensor cause the P0507 code?
Yes, a faulty MAF sensor can send incorrect air intake readings to the ECM, disrupting the idle control system and leading to a high idle RPM.
7. How do you fix the P0507 code on a 2008 Nissan Altima?
Potential fixes include cleaning or replacing the throttle body, repairing vacuum leaks, checking and possibly replacing the idle air control valve, or inspecting the MAF sensor.
8. Can resetting the ECM clear the P0507 code?
Resetting the ECM may temporarily clear the code, but if the underlying issue isn’t fixed, the code will likely return.
9. Is it safe to drive a 2008 Nissan Altima with the P0507 code?
While it may be safe to drive short distances, driving with a high idle RPM can cause poor fuel economy and additional wear on the engine, so prompt repairs are recommended.
10. How much does it typically cost to fix a P0507 code on a 2008 Nissan Altima?
Repair costs can vary depending on the cause, ranging from $50 to $150 for cleaning the throttle body to $300 or more if parts like the idle air control valve or MAF sensor need replacement.

-
have the same code tried to relearn throthle still surges between 1500-2100 rpm i did the ecm -throthle body and throthle pedal tried the relearn procedure with the scan tool aswell but the idle still surges
-
Try performing the idle relearn with a scanner with one coil disconnected. Then, reconnect the coil and perform the relearn procedure again. You may have to try several times, but if the problem persist, then you may have to replace the throttle body.
