Start by checking the thermostat, as it might be stuck open, causing the engine to take longer to reach operating temperature. If the thermostat is faulty, replacing it should resolve the issue. Let us know how it goes or if you have any further questions!
The engine picks up 90 degrees, it is the particulate filter that does not pick up enough temperature marks -50 degrees with the engine cold.

Check the temperature sensor for the particulate filter. A faulty sensor could be giving incorrect readings, affecting the filter's performance. Inspect the wiring and connections for any damage or corrosion. If the sensor is faulty, replacing it should help. Let us know if this resolves the issue or if you need further assistance.
