Description:

This error code, EPC 000127.01, is generated when the EPC detects low transmission oil pressure (system pressure) at an engine speed above 700 rpm. This indicates a potential issue with the transmission oil system that could affect its performance and longevity.

Reaction:

When this error is detected, the transmission may not receive adequate lubrication and cooling, leading to potential overheating, increased wear, and possible damage to transmission components. This can result in poor transmission performance and reduced operational efficiency.

Recommendations:

Check Oil Level and Quality:

• Verify that the transmission oil level is within the recommended range. Ensure the oil is clean and of the correct type specified by the manufacturer.

Inspect for Leaks:

• Examine the transmission system for any signs of oil leaks. Repair any leaks found to prevent loss of oil pressure.

Test Oil Pump:

• Check the functionality of the transmission oil pump. Ensure it is operating correctly and providing adequate pressure.

Inspect Pressure Sensor:

• Verify the accuracy and condition of the transmission oil pressure sensor. Replace if it is found to be faulty.

Examine Oil Filter:

• Ensure that the transmission oil filter is not clogged or restricted. Replace the filter if necessary.

Check for Blockages:

• Inspect the oil lines and passages for any blockages that could restrict oil flow. Clean or clear any obstructions found.

Reset and Test System:

• After addressing the above issues, reset the system and monitor the transmission oil pressure to ensure it is within the normal operating range.

Note:

Regular maintenance of the transmission oil system, including checking oil levels, changing filters, and inspecting for leaks, can help prevent low oil pressure issues and ensure optimal transmission performance.
