- Transmission Control Module (TCM) Power Up Temperature Sensor Performance

DTC P06AD

- Transmission Control Module (TCM) Power Up Temperature Sensor Circuit Low Voltage

DTC P06AE

- Transmission Control Module (TCM) Power Up Temperature Sensor Circuit High Voltage

Circuit/System Description

The transmission control module (TCM) power up temperature sensor is located inside of the control solenoid valve assembly, which has no

serviceable components. The TCM power up temperature sensor provides the temperature of the TCM when the TCM power is on. This

temperature reading is used in various shifting and diagnostic routines and also to protect the control solenoid valve assembly and TCM. This fault

is handled inside the TCM and no external circuits are involved.

Conditions for Running the DTC

P06AC

* No DTCs P0101, P0102, P0103, P0106, P0107, P0108, P0171, P0172, P0174, P0175, P0201, P0202, P0203, P0204, P0205, P0206, P0207,

P0208, P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, P0401, P042E, P0658, P0668, P0669, P06AC, P06AD, P06AE,

P0712, P0713, P0716, P0717, P0722, P0723, P0962, P0963, P0966, P0967, P0970, P0971, P215C, P2720, P2721, P2729, or P2730.

* The engine speed is 400 RPM or greater for 5 seconds.

* The ignition voltage is 8.6 volts or greater.

* Brake torque is not active.

* The torque signal is valid.

* The throttle position signal is valid.

P06AD

* No DTCs P06AD, P0716, P0717, P0722, or P0723.

* The engine speed is 400 RPM or greater for 5 seconds.

* The ignition voltage is 8.6 volts or greater.

P06AE

* The engine speed is 400 RPM or greater for 5 seconds.

* The ignition voltage is 8.6 volts or greater.

* DTC P06AE has not set this ignition cycle.

Conditions for Setting the DTC

P06AC

* The difference between the transmission fluid temperature (TFT) and TCM power up temperature is greater than 20-50掳C (36-90掳F),

depending on the average of the TFT, TCM substrate, and TCM power up temperatures.

* The difference between the TCM substrate temperature and TCM power up temperature is greater than 8-10掳C (14-18掳F) depending on the

average of the TFT, TCM substrate, and TCM power up temperatures.

* The above conditions have to be met for 5 minutes within a 6 minute period.

P06AD

The TCM power up temperature is -59掳C (-74掳F) or less for 1 minute.

P06AE

The TCM power up temperature is 165掳C (329掳F) or greater for 1 minute.

Action Taken When the DTC Sets

* DTC P06AC, P06AD, P06AE are Type B DTCs.

* The TCM defaults the TCM power up temperature to the TCM substrate temperature.

Conditions for Clearing the DTC

DTC P06AC, P06AD, P06AE are Type B DTCs.
