Figure 412 Function diagram for the EBP sensor
The function diagram for the EBP sensor includes the
following:
• EBP sensor
• Electronic Control Module (ECM)
• Variable Geometry Turbocharger (VGT)
• Exhaust Gas Recirculation (EGR)
Read all safety instructions in the "Safety Information" section of this manual before doing any procedures.
Function
The EBP sensor is a variable capacitance sensor
installed in a bracket mounted on the water supply
housing (Freon® compressor bracket).
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.
