Component Location
General Description
The AQS (Air Quality System) keeps air inside in the most suitable state for driver. In polluted area AQS detects hazardous gas and intercepts inflow automatically, Inversely, In fresh area it allows the inflow of air to prevent the shortage of air and the accumulation of carbon dioxide. The AQS sensor is located at front side of condenser and once hazardous gas is detected, it delivers the voltage signal to ECU for closing intake door.
DTC Description
DTC B1258 sets if the AQS Sensor signal is at or below 0.1 V for 0.3 seconds.
DTC Detecting Condition
Specification
** Voltage value of AQS sensor as a function of position of operating condition.
Preheating Time : (35 ± 2 sec.)
