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.
