Description:

This diagnostic trouble code is generated when the PTA control software detects that the transmission oil filter is restricted. The pressure switch of the transmission oil filter opens when the transmission oil temperature exceeds 40°C (104°F), indicating a potential restriction in the filter.

Reaction:

The warning remains active until the error is corrected, indicating a continuous issue with the transmission oil filter pressure.

Recommendations:

Check Transmission Oil Filter:

• Inspect the transmission oil filter for any signs of clogging or damage.
• Replace the filter if it is found to be restricted or dirty.

Inspect Pressure Switch:

• Ensure the pressure switch is functioning correctly.
• Replace the pressure switch if it is faulty.

Monitor Oil Temperature:

• Verify that the transmission oil temperature is within the normal operating range.
• Check for any issues with the transmission oil cooling system that might cause overheating.

Note:

Regular maintenance of the transmission oil filter and monitoring the transmission oil temperature can help prevent this issue from occurring. Ensure that the filter is replaced at the recommended service intervals.
