PTA 000177.00 – Transmission Oil Temperature Sensor, Temperature Very High

PTA 000177.00 (PTA 177.00)

Code: 000177.00

Shortcode: 177.00

Description:

This diagnostic trouble code is generated when the PTA control software detects that the transmission oil temperature exceeds 100°C (212°F). High transmission oil temperature can indicate a potential cooling system failure or heavy load conditions.

Reaction:

The warning remains active until the error is corrected, signaling a critical issue with the transmission oil temperature.

Recommendations:

Check Cooling System:

  • Inspect the transmission oil cooler for blockages or damage.
  • Ensure that the cooling fan and related components are functioning correctly.

Monitor Oil Levels:

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

Inspect Oil Quality:

  • Check the condition of the transmission oil for signs of degradation or contamination.
  • Change the oil if it is old or contaminated.

Assess Load Conditions:

  • Evaluate the operating conditions to ensure the transmission is not being overworked.
  • Reduce load if the transmission is being used beyond its capacity.

Note:

Regular maintenance of the transmission cooling system and monitoring of oil conditions are crucial to prevent overheating issues. Ensure the system is in optimal working condition to avoid high-temperature problems.
