What does the idle control system code mean?
What does the idle control system code mean?
The role of the Idle Control System is to manage the engine’s idle speed and meet the fluctuating load placed on the vehicle’s engine, which varies from the use of air-conditioning, heater, wiper, etc. Error Code P0507 means the idle speed is faster than normal. This code is sometimes triggered on vehicles with electronic throttle control.
When is the p0507 idle air control system higher than expected?
In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM.
Where is the idle air control motor located?
The idle speed is usually controlled by the Idle Air Control Motor, which is mounted on or the back side of Throttle Body’s Intake Manifold. Vehicles made since 2000 use ‘drive by wire system’, where the Idle Air System is incorporated straight to Electronic Throttle Body’s assembly.
What happens when idle speed is higher than expected?
In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set. An example of an Idle Air Control (IAC) valve: Most likely you’ll notice the idle speed is higher than normal.
What causes the idle control system rpm higher?
The P0507 code means the idle control system has excessively high RPM. The ECU has a specific rpm range the idle is allowed and when it is higher than expected the ECU sets the P0507 code. Once this code is triggered it puts the vehicle into a failsafe mode and the Check Engine Light is illuminated on the dashboard. What causes the P0507 code?

In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM.
In many cases, the idle speed that goes more than 200 RPM higher than the desired or expected speed will trigger the error code. More About Idle Control System. The idle speed is usually controlled by the Idle Air Control Motor, which is mounted on or the back side of Throttle Body’s Intake Manifold.
