Description Barometric Pressure Sensor (BPS) is a speed-density type sensor and is installed on the air cleaner assemby. It senses absolute pressure of the air cleaner assemby and transfers the analog signal proportional to the pressure to the ECM.
Circuit Diagram
Replacement 1. Discharge refrigerant from refrigeration system. 2. Replace faulty tube or hose. Cap the open fittings immediately to keep moisture or dirt out of the system. 3. Tighten joint of bolt or nut to specified torque.
Replacement 1. Disconnect the negative (-) battery terminal. 2. Recover the refrigerant with a recovery/ recycling/ charging station. 3. When the engine is cool, drain the engine coolant from the radiator. 4. Remove the expansion valve cover (A).
