The function diagram for the EBP sensor includes the following:
• EBP sensor
• Electronic Control Module (ECM)
• Variable Geometry Turbocharger (VGT)
• Exhaust Gas Recirculation (EGR)
Function
The EBP sensor is a variable capacitance sensor installed in a bracket mounted on the water supply housing (Freon® compressor bracket). The ECM supplies a 5 V reference signal that the EBP sensor uses to produce a linear analog voltage that indicates pressure. The EBP sensor measures exhaust back pressure so that the ECM can control the VGT and EGR systems.
