• BCP
• ICP
A Micro Strain Gauge (MSG) sensor measures pressure. Pressure to be measured exerts force on a pressure vessel that stretches and compresses to change resistance of strain gauges bonded to the surface of the pressure vessel. Internal sensor electronics convert the changes in resistance to a ratiometric voltage output.
The sensor is connected to the ECM by three wires:
• VREF
• Signal return
• Signal ground
The sensor receives the VREF and returns an analog signal voltage to the ECM. The ECM compares the
voltage with pre-programmed values to determine pressure.
