TFT Sensor Out Of Self Test Range
Your transmission fluid temperature sensor is reading outside the normal range during self-test, like a thermometer giving impossible readings. The ECU can't trust the temperature data to properly manage transmission shifting and cooling.
The ECU monitors the TFT sensor voltage during power-on self-test to verify it's within calibrated operating range. If the sensor voltage is too high, too low, or unresponsive during startup diagnostics, the fault is logged. The ECU cannot reliably use the sensor signal for transmission thermal management.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| TFT Sensor Voltage | 0.5-4.5 volts (approximately -40°C to 150°C) | Below 0.2V or above 4.8V during self-test |
| Self-Test Response | Sensor responds to temperature changes | No response or erratic behavior during diagnostic routine |
Code P1716 is a moderate fault. You can generally drive to a workshop, but avoid long trips or high-load driving (motorway, uphill towing) until it is diagnosed. If the code keeps returning after clearing, or if you notice the symptoms listed above worsening, do not delay professional diagnosis. Many moderate codes have multiple possible root causes — a mechanic with live OBD data can identify the exact fault more efficiently than part-by-part trial and error.
Once the fault is repaired, P1716 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.
The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.
