Pinpoint Test An: Transmission Fluid Temperature Sensor: Description
WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 1996 Ford RV Cutaway, 1996 Ford Pickup, 1996 Ford F-Super Duty, 1996 Ford Econoline, and 1996 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
DTC 0712 indicates TFT sensor circuit low input. DTC 0713 indicates TFT sensor circuit high input. DTC 1711 indicates TFT sensor out of self-test range. Perform this test only when directed here by QUICK TEST. To prevent replacing good components, be aware the following non-EEC areas may be at fault:
- Engine and/or transmission fluid level.
- Engine and/or transmission fluid temperature.
- Ambient temperature.
This test is intended to diagnose:
- TFT sensor.
- Wiring harness circuits (TFT and SIG RTN).
- Faulty Powertrain Control Module (PCM).
NOTE:
Voltage values are calculated for VREF equalling 5.0 volts. Values may vary 15 percent due to sensor and VREF variations. Transmission fluid temperature must be a minimum of 50°F (10°C) before taking TFT sensor resistance measurements.
