PTA 001387.01 – Lube Oil Pressure Sensor, Oil Pressure Too Low

PTA 001387.01 (PTA 1387.01)

Code: 001387.01

Shortcode: 1387.01

Description:

This diagnostic trouble code is generated when the PTA control software is unable to determine transmission lube oil pressure, indicating that the oil pressure is too low.

Reaction:

Limited or no function of the transmission until the error is corrected, indicating a critical issue with the lube oil pressure.

Recommendations:

Inspect Oil Pressure Sensor:

  • Verify that the lube oil pressure sensor is functioning correctly.
  • Replace the sensor if it is found to be faulty.

Check Oil Levels:

  • Ensure that the transmission lube oil level is correct.
  • Top off or replace the oil if necessary.

Inspect Oil Pump:

  • Verify the operation of the oil pump.
  • Repair or replace the pump if it is not providing adequate pressure.

Examine Wiring and Connectors:

  • Inspect all wiring and connectors associated with the oil pressure sensor for signs of damage or disconnection.
  • Repair or replace any damaged components.

Note:

Maintaining proper lube oil pressure is crucial for the reliable operation of the transmission. Regular checks and maintenance of the oil system and sensor can help prevent low-pressure issues.
