What is P0719?

The diagnostic trouble code (DTC) P0719 indicates an issue with the transmission fluid temperature (TFT) sensor circuit. This sensor plays a crucial role in monitoring the temperature of the transmission fluid to ensure optimal transmission performance. When the powertrain control module (PCM) detects a voltage signal from the TFT sensor that is outside the expected range, it triggers this code. Real-world implications include potential transmission overheating, erratic shifting, or even complete transmission failure if the issue is not addressed. The P0719 code is commonly seen in vehicles like the 2014-2018 Ford F-150 and the 2015-2018 Chevrolet Silverado, which can lead to decreased fuel efficiency and increased wear on transmission components. Ignoring this code can escalate repair costs and lead to more severe mechanical issues, making it crucial for vehicle owners to understand and address the P0719 code promptly.

Symptoms

Common symptoms when P0719 is present:

  • The check engine light remains illuminated, indicating a need for immediate attention.
  • Drivers may notice a delay in gear shifting or harsh shifts, causing an uncomfortable driving experience.
  • Fuel economy can decrease by 10-20%, leading to higher fuel costs over time.
  • Transmission may overheat, leading to decreased performance and potential failure.
  • Unusual noises from the transmission, such as grinding or whining, may occur, indicating internal issues.

Possible Causes

Most common causes of P0719 (ordered by frequency):

  1. The most common cause is a faulty transmission fluid temperature sensor, accounting for about 60% of cases.
  2. Wiring issues, such as damaged or corroded connectors in the sensor circuit, can also trigger the P0719 code.
  3. A malfunctioning PCM may misinterpret the sensor's readings, leading to erroneous signals.
  4. Less common but serious causes include internal transmission issues that may require extensive repairs.
  5. Rarer causes include software issues within the transmission control module (TCM) that may require a reflash or replacement.
