Volvo All Engines (2010 Emissions) Fault Code: SPN 3509 FMI 4 PID: SID 232 Sensor Supply Voltage 1

The control module provides the following sensors with 5V supply voltage
B37: Intake manifold air temperature (IMAT) and pressure sensor
B187: Aftertreatment Fuel Pressure Sensor
B166: EGR Differential Pressure Sensor

Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A14.EA:7 is less than 4.5?V

Observable symptoms
1) Low Power
2) Intake manifold pressure (IMP) gauge shows 0

Probable cause
1) Wiring harness
2) Connector
3) Sensor
4) Engine control module (ECM)

Detailed information
1) B32: Fan speed sensor
2) B37: Intake manifold air temperature (IMAT) and pressure sensor
3) B166: EGR Differential Pressure Sensor
4) B187: Aftertreatment Fuel Pressure Sensor
