No it is not simple to replace. The sensor is a part of the main circuit board & can only be replaced by a PCB tech with access to the software to calibrate the levels. Faulty pressure sensors mean replacement of the PCB controller. If it is faulty, it should be beeping and displaying an error code. If it isn't then it may not be the sensor. Open the panel and check the air hose is securely attached to the control module. Any air leakage can cause incorrect levels.
