DTC P0A2D (237)

DTC P0A2D  : Traction Motor Temperature Sensor Circuit High

NOTE:  Before you troubleshoot, review the general troubleshooting information .

DTC (Electric Powertrain)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Turn the vehicle to the OFF (LOCK) mode.

   -4. Turn the vehicle to the ON mode.

   -5. Check for Pending or Confirmed DTCs with the HDS.

   DTC Description	Confirmed DTC	Pending DTC	Freeze Frame
   P0A2D Traction Motor Temperature Sensor Circuit High

   Is DTC P0A2D indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure. The system is OK at this time. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

2. Determine possible failure area (TMOT line, SGTEMP/SGTMOT line)

   -1. Check for Pending or Confirmed DTCs with the HDS.

   DTC Description	Confirmed DTC	Pending DTC	Freeze Frame
   P0713 Transmission Fluid Temperature Sensor Circuit High
   P0A2D Traction Motor Temperature Sensor Circuit High
   P0CF1 PCU Coolant Temperature Sensor Circuit High

   Are DTC P0713, P0A2D, and P0CF1 indicated at the same time?

   YES 

   Go to step 5.

   NO 

   Go to step 3.

3. Open wire check (TMOT line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Do the 12 volt battery terminal disconnection procedure .

   -3. Disconnect the following connectors.

   PCU 33P connector

   Motor temperature sensor 6P connector

   -4. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	PCU 33P connector: disconnected
   	Motor temperature sensor 6P connector: disconnected
   Test point 1	PCU 33P connector No. 10
   Test point 2	Motor temperature sensor 6P connector (female terminals) No. 3:

   Is there 1.0 Ω or less?

   YES 

   Go to step 4.

   NO 

   Repair an open in the TMOT wire between the traction motor temperature sensor and the PCU.

4. Traction motor temperature sensor check

   -1. At the sensor side, check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	PCU 33P connector: disconnected
   	Motor temperature sensor 6P connector: disconnected
   Test point 1	Motor temperature sensor 6P connector (male terminals) No. 2:
   Test point 2	Motor temperature sensor 6P connector (male terminals) No. 3:

   Is there continuity?

   YES 

   Replace the PCU .

   NO 

   Faulty traction motor temperature sensor. Replace the transmission (e-CVT) assembly .

5. Open wire check (SGTEMP/SGTMOT line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Do the 12 volt battery terminal disconnection procedure .

   -3. Disconnect the following connectors.

   PCU 33P connector

   Motor temperature sensor 6P connector

   -4. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	PCU 33P connector: disconnected
   	Motor temperature sensor 6P connector: disconnected
   Test point 1	PCU 33P connector No. 17
   Test point 2	Motor temperature sensor 6P connector (female terminals) No. 2:

   Is there 1.0 Ω or less?

   YES 

   Go to step 6.

   NO 

   Repair an open in the SGTEMP/SGTMOT wire between the traction motor temperature sensor and the PCU.

6. Traction motor temperature sensor check

   -1. At the sensor side, check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	PCU 33P connector: disconnected
   	Motor temperature sensor 6P connector: disconnected
   Test point 1	Motor temperature sensor 6P connector (male terminals) No. 2:
   Test point 2	Motor temperature sensor 6P connector (male terminals) No. 3:

   Is there continuity?

   YES 

   Replace the PCU .

   NO 

   Faulty traction motor temperature sensor. Replace the transmission (e-CVT) assembly .
