Description:

This error code, EPC 000126.16, indicates that the pressure switch on the transmission oil filter has been closed for more than three seconds at a transmission oil temperature above 28°C (82°F) and an engine speed exceeding 700 rpm. This suggests that the transmission oil filter is restricted and needs to be changed.

Reaction:

When this error is detected, the transmission may experience reduced lubrication and cooling efficiency, leading to potential overheating and increased wear on transmission components.

Recommendations:

Change Transmission Oil Filter:

• Replace the transmission oil filter with a new one to ensure proper flow and filtration of the transmission oil.

Inspect Oil Filter and Housing:

• Check the oil filter housing and associated components for any signs of damage or blockages. Clean or repair as necessary.

Monitor Oil Pressure and Temperature:

• After replacing the oil filter, monitor the transmission oil pressure and temperature to ensure they return to normal operating ranges.

Check for Contamination:

• Inspect the old oil filter for signs of contamination or debris that could indicate other underlying issues within the transmission system.

Reset and Test System:

• After performing the above actions, reset the system and test the transmission to ensure proper operation and that the error code does not reoccur.

Note:

Regular maintenance of the transmission oil filter is crucial for the optimal performance and longevity of the transmission system. Timely replacement of the oil filter can prevent issues related to restricted oil flow and maintain efficient transmission operation.
