    I think we've seen pressure too low, but I don't recall one with pressure too high.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Indeed it can happen when frozen or the sensor is plugged up with solids.

    Did you know that you can install a heated line in the adblue and or heater in car to plugin and maintain circulation of air in car works well to stop this problem before commenced cold startup?

    Example
