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. 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).
Inspection 1. Connect the battery voltage and check the blower motor rotation. 2. If the blower motor voltage is not operated well, substitute with a known-good blower motor and check for proper operation. 3. If the problem is corrected, replace the blower motor.
