Pinpoint Test An: Transmission Fluid Temperature Sensor: Description
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.
