| DETECTION CONDITION |
- Actual idle speed is lower than expected by 100 RPM
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.

- 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 PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
