PTA 003509.01 – 5-Volt Supply Voltage Faulty

PTA 003509.01 (PTA 3509.01)

Code: 003509.01

Shortcode: 3509.01

Description:

This diagnostic trouble code is generated when the PTA control software detects a faulty 5-volt supply voltage to the lube oil pressure sensor, indicating a short circuit to ground.

Reaction:

Limited or no function of the transmission until the error is corrected, indicating a critical issue with the 5-volt supply voltage.

Recommendations:

Inspect Power Supply Circuit:

  • Check the power supply circuit for any signs of short circuits to ground.
  • Repair any identified issues in the circuit.

Test Voltage Output:

  • Measure the 5-volt supply voltage using a multimeter.
  • Replace any components that are causing faulty voltage output.

Examine Wiring and Connectors:

  • Inspect all wiring and connectors associated with the power supply for signs of damage or wear.
  • Repair or replace any damaged components to ensure proper electrical connections.

Verify Sensor Integrity:

  • Ensure the lube oil pressure sensor is not causing the short circuit.
  • Replace the sensor if it is found to be faulty.

Note:

Maintaining proper voltage levels is crucial for the reliable operation of the transmission. Regular checks and maintenance of the power supply and sensor circuits can help prevent voltage-related issues.
