Diagnostic code P0507 OBD2 is set on vehicles that have electronic throttle control. This electronic control is based on sensors and electronics to control the accelerator, unlike other vehicles that have a cable that runs from the accelerator pedal to the engine. When we see that this DTC code is established, which implies that the Power Train Control Module (PCM) has determined that the idle speed of the engine is more than the RPM (Revolution per minute), which are already predetermined
For example, in General Motors vehicles (although it occurs in other models as well), if the idle speed exceeds by more than 200 RPM than expected, the code P0507 OBDII will be established.
