1.
Problem verification:

Problem verification
?1.
Turn the vehicle to the ON mode.

?2.
Check the parameter(s) below with the HDS.

Threshold
Current conditions
Values
Unit

Unit
CVTF Temp Sensor (V)
Less than 0.07
V
    

Do the current condition(s) match the threshold?

     
YES
     
     
     
The failure is duplicated. Go to step 2.
     
NO
     
     
     
Intermittent failure, the system is OK at this time. Check for an intermittent short to ground in the TATF wire between the transmission fluid temperature sensor and the PCM. 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.
Transmission fluid temperature sensor check:

Transmission fluid temperature sensor check
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Disconnect the following connector.
Solenoid wire harness A 8P connector

?3.
Turn the vehicle to the ON mode.

?4.
Check the parameter(s) below with the HDS.

Do the current condition(s) match the threshold?

     
YES
     
     
     
The transmission fluid temperature sensor is OK. Go to step 3.
     
NO
     
     
     
Faulty transmission fluid temperature sensor. Replace solenoid wire harness A.?
3.
Shorted wire check (TATF line):

Shorted wire check (TATF line)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Jump the SCS line with the HDS, and wait more than 1 minute.
NOTE: This step must be done to protect the PCM from damage.


?3.
Disconnect the following connector.
PCM connector C (51P)

?4.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
 
Solenoid wire harness A 8P connector: disconnected
 
PCM connector C (51P): disconnected
Test point 1
PCM connector C (51P) No. 37
Test point 2
Body ground

Is there continuity?

     
YES
     
     
     
Repair a short to body ground in the TATF wire between the solenoid wire harness A and the PCM.?
     
NO
     
     
     
The TATF wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or replace the original PCM.?
