POST UPDATED IN February, 2023
P1705 Code failures by brands
Description of DTC code P1705
The Transmission Range Sensor (TR) is a Hall-effect sensor incorporated in the TCM (Transmission Control Module). It detects the automatic transmission range and reports it to the TCM, which in turn reads the voltage and adjusts the automatic transmission range accordingly.
The Transmission Control Module continuously monitors the Transmission Range Sensor to check for proper transmission range performance. If the transmission range circuit does not indicate Stop/Neutral during one of these self-tests, the P1705 OBD2 fault code will be set.
Symptoms of fault code P1705
- Check Engine light is ON.
- After a complete stop, a loss of power is noticeable.

- The transmission range sensor may be faulty.
Possible solutions of the DTC code P1705
The steps to follow to troubleshoot DTC P1705 OBD2 are as follows:
- Consult the Technical Service Bulletins.
- Check all the Transmission Range Sensor circuit components for damage caused by corrosion, burns, or wear. If one of these conditions is discovered, repairs or replacements are necessary.
- Measure the voltages of the Transmission Range Sensor Check that the power supply and reference signal values are the same as the manufacturer's specifications. If you discover deficiencies in one of these values, make the appropriate corrections.
