Conditions For Setting The DTC
- No VSS DTCs P0722 or P0723.
- No Transmission Component Slipping DTC P1870.
- Engine is running.
- TFT is between 20 A/D (Analog/Digital) counts and 248 A/D counts.
- TFT is between -40°C (-40° F) and +21°C (69.8°F) at engine start-up.
- Engine coolant temperature is greater than 70°C (150°F).
- Engine coolant temperature has changed by greater than 50°C (90°F) since engine start-up.
- Vehicle speed has been greater than 5 mph for greater than 410 seconds since engine start-up (cumulative timer).
- TCC slip speed has been greater than 120 RPM for greater than 410 seconds since engine start-up (cumulative timer).
- Battery voltage is between 10 and 16 volts.
All of the above is true and either of the following occurs:
- If the sensor is stuck, the TFT has not changed for greater than 2 counts (from start-up temperature) for greater than 410 seconds.
- If the sensor shows an unrealistic change, the TFT exhibits a change delta of greater than 20°C (36°F), greater than 14 times in 7 seconds.
