DTC P0507:00

IAC system RPM higher than expected
DETECTION CONDITION
• Actual idle speed is higher than expected by 200 rpm for 14 s when the brake pedal is depressed (brake switch is on) and steering wheel is held straight ahead (power steering pressure switch is off).
Note
• If the atmospheric pressure is less than 72.3 kPa {542 mmHg, 21.3 inHg} or the 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).
• MIL illuminates if the PCM detects the above malfunction condition 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 the first drive cycle.
• FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
• DTCs are stored in PCM memory.
POSSIBLE CAUSE
• Vacuum hose misconnection
• Electronic throttle control system malfunction
• PCM malfunction
