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
Inspection 1. Ignition "ON" 2. Using the scan tool. 3. Emit intensive light toward photo sensor using a lamp, and check the output voltage change. 4. The voltage will rise with higher intensive light and reduce with lower intensive light.
Inspection 1. Ignition "OFF" 2. Disconnect ambient temperature sensor. 3. Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature. 1. Sensor Ground2.
