DTC P0AAE-123, P0AAF-123: Hybrid Battery Pack Air Temperature Sensor "A" Circuit Low; Hybrid Battery Pack Air Temperature Sensor "A" Circuit High [12/2014 - ]: Description
- The inlet air temperature sensor (battery) is mounted on the HV battery. The resistance of the sensor varies in accordance with changes in the intake air temperature. The characteristics of the inlet air temperature sensor are the same as those of the battery temperature sensor. Refer to DESCRIPTION . The battery smart unit uses signals from the inlet air temperature sensor to control the air volume of the battery cooling blower assembly.
| DTC No. | INF Code | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| P0AAE | 123 | The inlet air temperature sensor output voltage is lower than the specified value (short circuit) and the detected temperature is higher than the specified value. (1 trip detection logic) |
|
| P0AAF | The inlet air temperature sensor output voltage is higher than the standard value (short to +B or open) and the detected temperature is lower than the specified value. (1 trip detection logic) |
HINT:
After confirming that DTC P0AAE-123 or P0AAF-123 is output, use the Techstream to check "Inhaling Air Temp" in the HV ECU data list.
| Displayed Temperature | Malfunction |
|---|---|
| -45°C (-49°F) or less | Open or +B short circuit |
| 95°C (203°F) or more | GND short |
