Code P06AC Cadillac Description

The Transmission Control Module (TCM) power-up temperature sensor is located inside of the control solenoid valve assembly which has no serviceable parts. The Transmission Control Module power-up temperature sensor provides the temperature of the Transmission Control Module when the Transmission Control Module power is on. This temperature reading is used in various shifting and diagnostic routines and also to protect the control solenoid valve assembly and Transmission Control Module. This fault is handled inside the Transmission Control Module and no external circuits are involved. The Diagnostic Trouble Code (DTC) will be set if the TCM detects an 8 - 10°C (14 - 18°F) or greater difference between the TCM substrate temperature and TCM power up the temperature, which depends on the average transmission fluid temperature, TCM substrate temperature, and TCM power up the temperature.
