HYBRID CONTROL SYSTEM, Diagnostic DTC:P0A2B-250, P0A2E-248

DTC Code DTC Name
P0A2B-250 Drive Motor "A" Temperature Sensor Circuit Range / Performance
P0A2E-248 Drive Motor "A" Temperature Sensor Circuit Intermittent

DESCRIPTION

The resistance of the thermistor built into the motor temperature sensor changes in accordance with changes in MG2 temperature. The lower the MG2 temperature, the higher the thermistor resistance. Conversely, the higher the MG2 temperature, the lower the resistance.

Tech Tips

The term "drive motor A" indicates MG2.

P0A2E 248 Unusual sudden change in motor temperature sensor output occurs and the condition continues, or unusual sudden change in motor temperature sensor output occurs repeatedly.

CAUTION / NOTICE / HINT

Tech Tips


  • If DTC P0A2B-250 is output, clear the DTCs, perform the following procedure, and check that the same DTC is not output after the repair.


    1. Drive the vehicle (stop and go driving) on urban roads for approximately 5 minutes.

      If the Data List item "Motor Temp No1" shows both increases and decreases in temperature, suspected areas indicated by this DTC are not malfunctioning.

  • If DTC P0A2E-248 is output, clear the DTCs, perform the following procedure, and check that the same DTC is not output after the repair.


    1. Turn the ignition switch to ON (READY) and wait for 30 seconds or more.

    2. Drive the vehicle for approximately 5 minutes according to the freeze frame data items "Vehicle Spd", "Motor Temp No1" and "Motor Temp No2".
