Conditions for Setting the DTC
P0667 - Fail Case 1
* Vehicle speed is greater than 8 km/h (5 mph) for 200 seconds cumulative.
* The TCM Temperature parameter is between -50 and +21锟斤拷C (-58 and +70锟斤拷F).
* The TCM Temperature parameter has changed by less than 2.0锟斤拷C (3.6锟斤拷F) in 100 seconds.
* The Trans. Fluid Temp. parameter is greater than 70锟斤拷C (158锟斤拷F).
* The TFT has increased by 55锟斤拷C (99锟斤拷F) since startup.
P0667 - Fail Case 2
* Vehicle speed is greater than 8 km/h (5 mph) for 200 seconds cumulative.
* The TCM temperature parameter is between 120-150锟斤拷C (248-302锟斤拷F).
* The TCM temperature parameter has changed by less than 2.0锟斤拷C (3.6锟斤拷F) in 100 seconds.
* The Trans. Fluid Temp. parameter is greater than 70锟斤拷C (158锟斤拷F).
* The Trans. Fluid Temp. parameter has increased by 55锟斤拷C (99锟斤拷F) since startup.
P0667 - Fail Case 3
The TCM temperature parameter changes by greater than or equal to 20锟斤拷C (36锟斤拷F) 14 times over 7 seconds.
P0668
The TCM temperature is parameter greater than or equal to 161锟斤拷C (321锟斤拷F) for greater than 10 seconds.
P0669
The TCM temperature parameter is less than or equal to -61锟斤拷C (-77锟斤拷F) for greater than 10 seconds.
Action Taken When the DTC Sets
DTCs P0667, P0668, and P0669 are Type B DTCs.
Conditions for Clearing the DTC
DTCs P0667, P0668, and P0669 are Type B DTCs.
Diagnostic Aids
This DTC may be set due to an overheating condition. The system is operating normally when the Trans. Fluid Temp. parameter is within 10锟斤拷C (18
锟斤拷F) of the TCM temperature parameter.
