AutoCodes – BMW – P0507 BMW

P0507 BMW 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.

What it means: P0507 BMW indicates Idle Control System RPM Higher Than Expected.
Common causes: Common causes include Dirty throttle body, Electric throttle control actuator misadjusted or damaged, Faulty Electric throttle control actuator.
Severity: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0507 BMW 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.)

Frequently Asked Questions about P0507 BMW Code

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

- Common symptoms include high idle speed, rough idling, stalling, and potential fluctuations in engine speed.

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

- Common causes can include a faulty idle air control valve, vacuum leaks, throttle body issues, engine misfires, or a dirty/faulty mass airflow sensor.

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

- Diagnosing the issue may involve checking for vacuum leaks, inspecting the idle air control valve, scanning for other related fault codes, and testing the throttle body.

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

- Yes, a dirty throttle body can restrict airflow and lead to higher than expected idle RPM, triggering the P0507 fault code.

5. What is the recommended repair for OBDII code P0507 in a BMW?

- Depending on the root cause, repairs may include cleaning or replacing the idle air control valve, fixing vacuum leaks, cleaning the throttle body, addressing engine misfires, or replacing faulty sensors.
