P1711 Code: Transmission Fluid Temperature Sensor Out of Self-Test Range (Ford)

On Ford, Lincoln and Mercury vehicles, the P1711 code means the transmission fluid temperature sensor was out of range during the self-test. You may notice somewhat harsh shifts when cold. Often the test was simply run with the transmission too cold or too hot.

What the P1711 code means

P1711 is a manufacturer-specific code: the 1 in the second position means each automaker defines what it means, not the generic SAE standard. The most widespread definition is the one used by Ford, Lincoln and Mercury. If your vehicle is another brand, confirm the code text with a scan tool that supports that manufacturer.

ManufacturerMeaning of P1711
Ford, Lincoln and MercuryTransmission fluid temperature sensor out of self-test range

In Ford automatic transmissions the computer controls shifts and torque converter lockup, and it watches the fluid temperature with the TFT sensor.

The computer sets the P1711 code when, during the self-test, the transmission fluid temperature is not in the expected range. Often it only means the test was done with the transmission too cold or too hot.

Before you start repairs, confirm the make, model, year and engine. With manufacturer codes, the same number can change even between engines from the same brand.

P1711 code symptoms

  • Check engine light on.
  • Somewhat harsh shifts when cold.

Likely causes of the P1711 code

  1. Self-test run with the transmission cold. Confirm it with the tests in the diagnosis section.
  2. TFT sensor. Confirm it by comparing its reading with the real value.
  3. Transmission connector. Check the lock tab, the pins and any sign of moisture or corrosion.

How to diagnose the P1711 code step by step

  1. Repeat the test with the transmission at working temperature.
  2. Compare the TFT reading with the real temperature.
  3. Measure the sensor resistance.

How to fix the P1711 code

  • Repeat the self-test.
  • Replace the sensor if it reads wrong.

Technical reference data

  • Transmission working temperature: 70 to 95 °C (158 to 203 °F).
  • P1xxx codes are manufacturer-specific: confirm the definition with a scan tool that supports your brand.
  • Reference values: check the manufacturer data for your vehicle.

Brand-specific notes

Before you condemn the sensor, repeat the test with the transmission properly warmed up. That alone clears many of these codes.

Frequently asked questions about P1711

What does the P1711 code mean on a Ford?
It means the transmission fluid temperature sensor was out of range during the self-test. You may notice somewhat harsh shifts when cold.
Does P1711 mean the same thing on every brand?
No. It is a manufacturer-specific code, so on other brands it may not exist or may mean something different. Confirm it with a scan tool that supports your make.
Can I drive with a P1711 code?
Yes. With a P1711 code severity is low and the vehicle normally drives as usual. Shifts may feel a bit harsh until the transmission warms up.
How much does it cost to fix P1711?
Roughly $0 to $400 on a Ford. Repeating the test costs nothing, while a new sensor or transmission connector repair costs more.
Will a P1711 code clear itself?
It can, if the test was run with the transmission at the wrong temperature and passes next time. A bad sensor brings the code back.
What is the most common cause of P1711?
A self-test run with the transmission cold or too hot. The TFT sensor and the transmission connector are the next things to check.
