resistance changes with temperature. The lower the temperature, the higher the resistance of the sensor. The higher the temperature, the lower the
resistance of the sensor. The drive motor generator battery control module (BECM) uses the air inlet and outlet temperature sensors to determine if
air is circulating through the drive motor generator battery assembly.
Conditions for Running the DTC
* The ignition is ON.
* The 12 V battery voltage is 9-18 V.
Conditions for Setting the DTC
P0AAF and P0AB4
The hybrid battery pack air temperature sensor 1 or 2 is less than -40锟斤拷C (-40锟斤拷F).
P0AAE and P0AB3
The hybrid battery pack air temperature sensor 1 or 2 is greater than 95锟斤拷C (203锟斤拷F).
P0AAD
The hybrid battery cooling fan is ON and the difference between sensor 1 and 2 is greater than 10锟斤拷C (50锟斤拷F) difference for 9 seconds.
P0AB2
The hybrid battery cooling fan is ON and the outlet air temperature is greater than maximum hybrid battery temperature value by 10锟斤拷C (50锟斤拷F) for 9
seconds.
Action Taken When the DTC Sets
* DTCs P0AAD, P0AAE, P0AAF, P0AB2, P0AB3, and P0AB4 are type B DTCs.
* The drive motor generator battery sends a message to the hybrid powertrain control module to reduce the power by 50 percent.
Conditions for Clearing the DTC
DTCs P0AAD, P0AAE, P0AAF, P0AB2, P0AB3, and P0AB4 are type B DTCs.
