    Hi. I have 2023 Kenworth T680
    Air restrict is going up 100% when it’s uphill.
    All filters including Air Filter changed today. Did not help. Can someone help ?

    Because of the symbols on the dash I’ve wondered about that. Is that for the air filter or the DPF?

    Check Restriction sensor on the air filter housing. Make sure plugged in as it can be frequently disconnected for engine service work. Check wiring and pull test wires for being broken inside the insulation.

    Thank you. I will check the sensor. This sign is coming up when it’s uphill only.
    Disappears when there is not uphill.
