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.
DTC P1724 symptoms
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
- Loss of vehicle control
- Complete transmission failure
How to diagnose DTC P1724
To diagnose DTC P1724, follow these steps:
- Use an OBD-II scanner to confirm the presence of the P1724 code.
- Inspect the Transmission Fluid Temperature sensor and its wiring for damage or corrosion.
- Check the transmission fluid level and condition.
- Test the TFT sensor using a multimeter to ensure it operates within specifications.
- Examine the ECM for any software updates or faults.
How to fix DTC P1724 step-by-step instructions
To fix DTC P1724, follow these steps:
- Repair or replace any damaged wiring or connectors related to the TFT sensor.
