DTC P0507:00

Idle air control system RPM higher than expected
DETECTION CONDITION
•  The actual idle speed is higher than expected by 200 rpm for 14 s, when brake pedal is depressed (brake switch is ON) and steering wheel is held straight ahead.
Note
•  If atmospheric pressure is less than 72.3 kPa {542 mmHg, 21.3 inHg} or intake air temperature is below -10 °C {14 °F}, the PCM cancels diagnosis of P0507:00.
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The MIL illuminates if the PCM detects the above malfunction conditions in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
•  PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Vacuum hose misinstallation
•  Electronic throttle control system related sensor malfunction
―  APP sensor malfunction
―  TP sensor malfunction
•  PCM malfunction
