P0507 Nissan 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 Nissan Description

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. The operating of the throttle valve is varied to allow for optimum control of the engine idling speed. The ECM calculates the actual engine speed from signals of crankshaft position sensor (POS) and camshaft position sensor.
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 Nissan?

  • 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 Nissan?

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.

Code Tech Notes

If there are no intake leaks, clean throttle body, adjust engine idle and erase engine code. If the code comes back you may have to replace the Electric Throttle Control Actuator (Motor) to repair the problem.

Frequently Asked Questions about P0507 Nissan Code

1. What are the common symptoms of OBDII code P0507 in a Nissan?

- Common symptoms include high idle speed, the engine racing while in neutral, and potential stalling when coming to a stop.

2. What are the possible causes of OBDII code P0507 in a Nissan?

- The most common causes are a dirty or faulty idle air control valve (IACV), a vacuum leak, a malfunctioning throttle body, or issues with the intake manifold gasket.

3. How can I diagnose the cause of OBDII code P0507 in my Nissan?

- To diagnose the issue, you can use a scan tool to monitor the idle speed and IACV operation, visually inspect for any vacuum leaks, check the throttle body for carbon buildup, and perform a smoke test to detect intake leaks.

4. Can a dirty throttle body cause OBDII code P0507 in a Nissan?

- Yes, a dirty throttle body can restrict airflow and disrupt the idle control system, leading to an increase in engine RPM and triggering code P0507.

5. Is it safe to drive my Nissan with OBDII code P0507?

- It is generally not recommended to drive the vehicle with code P0507, as the high idle speed can affect drivability and potentially lead to further damage if left unresolved.

6. How can I fix OBDII code P0507 in my Nissan?

- Possible solutions include cleaning or replacing the IACV, repairing any vacuum leaks, cleaning the throttle body, and ensuring proper sealing of the intake manifold gasket.

7. Will resetting the ECU clear OBDII code P0507 in my Nissan?

- Resetting the ECU may temporarily clear the code, but it is important to address the underlying issue causing the high idle speed to prevent the code from reappearing.

8. Can a faulty mass airflow sensor trigger OBDII code P0507 in a Nissan?

- While a faulty mass airflow sensor can impact engine performance, it is not a common cause of code P0507. Focus on checking the IACV, vacuum system, throttle body, and intake manifold for potential issues.

9. How do I prevent OBDII code P0507 from recurring in my Nissan?

- Regular maintenance, such as cleaning the throttle body and IACV, checking for vacuum leaks, and ensuring proper installation of components, can help prevent the code from reoccurring.

10. Is it necessary to visit a mechanic for OBDII code P0507 in my Nissan, or can I fix it myself?

- Depending on your mechanical skills and equipment, you may be able to diagnose and fix the issue yourself. However, if you are unsure or unable to resolve the problem, it is recommended to seek professional help to prevent further damage.

  • help me Nissan altima 2003 2.0 Engine p0507 and I replaced the throttle body is still doing the samething if I star the Engine the RPM going to 200 RPM is not come down

  • You mean 2000 RPMS?
    After replacing the throttle body you have to adjust the base idle.

  • I have a 2019 Nissan Versa SV and the check engine light came on with code of P0507. When accelerating the RPMs is above 2000, yet vehicle is slowly rising in speed with gas pedal pushed down as normal. What is your suggestion? Thank you kindly

    Reply to Comment

    • P0507 means the engine is idling higher than the ECM expects, but the symptom you described—high RPM with slow acceleration—is also making me think there may be a transmission issue, especially since the 2019 Versa uses a CVT.

      I would start by checking the throttle body first. A dirty throttle body is the most common cause of P0507 on these cars, and after cleaning it, the throttle idle relearn procedure usually needs to be performed. Also inspect for any intake air leaks and make sure all intake hoses are securely connected. If the idle speed is normal but the engine revs above 2,000 RPM without the vehicle accelerating properly, have the CVT checked as well, since a slipping transmission can produce those symptoms even though it won't cause P0507.

      My suggestion would be to fix the P0507 first by inspecting the throttle body, intake system, and throttle actuator. If the high RPM with poor acceleration remains after the code is resolved, the transmission should be diagnosed separately.
