OBD-II DTC P1724 – TFT Sensor In Range Failure High

DTC P1724 meaning

DTC P1724 refers to a Diagnostic Trouble Code indicating a “TFT Sensor In Range Failure High.” This code is associated with the Transmission Fluid Temperature (TFT) sensor, which monitors the temperature of the transmission fluid. When the sensor reports a temperature that is higher than the expected range, the engine control module (ECM) triggers this code to alert the technician of a potential issue.

Common symptoms associated with DTC P1724 may include:

  • Transmission overheating
  • Erratic shifting or harsh shifts
  • Decreased fuel efficiency
  • Check Engine Light illuminated
  • Transmission slipping or failure to engage

DTC P1724 causes

Several factors can lead to the triggering of DTC P1724, including:

  • Faulty Transmission Fluid Temperature sensor
  • Wiring issues, such as shorts or open circuits
  • Corroded or loose electrical connections
  • Faulty engine control module (ECM)
  • Contaminated or low transmission fluid

DTC P1724 seriousness

DTC P1724 can be serious as it indicates a potential overheating issue with the transmission. If left unaddressed, it may lead to:

  • Severe transmission damage
  • Increased repair costs
