Conditions for Clearing the DTC



DTCs P0667, P0668, and P0669 are Type B DTCs.



Diagnostic Aids



The transmission control module (TCM) temperature sensor is located inside of the control solenoid valve assembly and its output should resemble



that of the transmission fluid temperature (TFT) sensor output.

Circuit/System Verification



1. Engine idling at normal operating temperature, verify the scan tool TCM Temperature parameter is between -247 and +247掳C (-412 and



+477掳F).



瀚慖f not within the specified range, replace the control solenoid valve assembly.



2. Operate the vehicle at 64 km/h (40 mph) for 10 minutes. Monitor the TCM Temperature, TCM Power-up Temperature, and the Trans. Fluid



Temp. parameters with a scan tool. The TCM Temperature and the Trans. Fluid Temp. parameters should be within 20掳C (36掳F) of each



other, and the TCM Temperature and TCM Power-up Temperature parameters should be within 10掳C (18掳F) of each other.



瀚慖f the TCM Temperature and TCM Power-up Temperature parameters are not within 10掳C (18掳F), or the TCM Temperature and Trans.



Fluid Temp. parameters are not within 20掳C (36掳F), then replace the control solenoid valve assembly.



3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the



conditions that you observed from the Freeze Frame/Failure Records data.



Repair Instructions



Important:



* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and



Inspection/Programming and Relearning) following all transmission related repairs.



* Before replacing the TCM, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection (See:



Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General



Diagnostics/6T70/6T75 - Automatic Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).



Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
