PTA 523917.04 – Hydrostatic Speed Sensor, Voltage in Channel 2 Too Low
PTA 523917.04 (PTA )
Code: 523917.04
Shortcode:
Description:
This diagnostic trouble code is generated when the PTA control software detects that the voltage at channel 2 of the hydrostatic speed sensor is too low, indicating a short to ground in the sensor circuit.
Reaction:
Limited or no function of the transmission until the error is corrected, indicating a critical issue with the hydrostatic speed sensor circuit.
Recommendations:
Inspect Sensor Circuit:
- Check the sensor circuit for any signs of short circuits to ground.
- Repair any identified issues in the circuit.
Test Hydrostatic Speed Sensor:
- Measure the voltage at channel 2 using a multimeter.
- Replace the sensor if it is producing abnormally low voltage readings.
Examine Wiring and Connectors:
- Inspect all wiring and connectors associated with the hydrostatic speed sensor for signs of damage or corrosion.
- Repair or replace any damaged components to ensure proper electrical connections.
Ensure Proper Grounding:
- Verify that the sensor circuit is properly grounded.
- Correct any grounding issues that may be causing low voltage readings.
Note:
Low voltage readings from the hydrostatic speed sensor can lead to severe operational problems. Regular inspection and maintenance of the sensor and its circuitry are essential to prevent these issues.
