DETECTION CONDITION AND POSSIBLE CAUSE (DTC P0507)

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 (PSP) switch is off).
    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.

  • PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
  • FREEZE FRAME DATA is available.
  • The DTC is stored in the PCM memory.
