If the tube that goes from the pressure transducer to the outside breather valve gets kinked it can cause false pressure readings and/ or cause leaking air pressure
Check the tube that goes to the breather from the pressure transducer. If it is kinked straighten and re-route it to prevent it from kinking. If it is real bad it will need to be replace. This tube is located on the back box circuit board and goes to the breather vent on the back box.
