EV MOTOR TEMPERATURE SENSOR OTC POA2B, POA2C, POA2D, POA2F

Disconnect the harness connector to the temperature sensor at the transaxle .
Measure the resistance between the two pins
shown .
Resistance
105-133 kO
5-36 kO
If the res istance is:
• Within specification , go to Step 5.
• Not within specification , replace the
automatic transaxle and go to Step 6.

5.

Visually check the control wiring harness and extension wire between the PCM and transaxle
for a damaged wire or short circuit to ground . Check for a damaged pin or pin not fully inserted
into the connector.
• If damage is found , repair or replace the control wiring and/or extension wire .
• If no visual damage is found , use an ohmmeter to check the resistance in the control
harness and extension wire between the PCM and the transaxle . If the resistance is more
than 10, repair or replace the control wiring or extension wire.
After repairs are completed , go to Step 7.

6.

If transaxle was replaced , remove the fill plug.

Filling and checking of fluid level is
done through valve body side cover

Use a funnel to add approximately 5-6 quarts
of SP-4-M ATF through the fill plug opening.
Reinstall the fill plug.
Attach the GOS to the OLC and select vehicle ,
A/T menu , Current Data and "Oil Temperature
Sensor".
Start the engine and shift to Park. When the
ATF is 122°F-140°F (50-60°C) , remove the
level checking plug. The level is correct when
oil flows from the level checking plug in a thin
steady stream .

ATF TEMPERATURE= 122 - 140F (50- 60C)
SHIFT LEVER IN " P" AND ENGINE RUNNING

Collect and dispose of any excess fluid in
accordance with local regulations .
7.

Clear the OTC in the Bluelink system according to instructions in TSB 12-BE-005-2.

8.

Drive the vehicle for two key-on/key-off cycles to confirm the OTC do not return .
