DTC P0506:00: Notes

• Actual idle speed is lower than the specified engine speed (varies according to the engine coolant temperature) for 14 s  when the brake pedal is depressed (brake switch is on) and the 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 the diagnosis of P0506:00.
