3509-2
Sensor Supply Voltage 1 : Erratic, Intermittent,
or Incorrect
The Electronic Control Module (ECM) detects a fault in the 5 VDC sensor supply
circuit supplied on the following pins:
J2:8
J2:9
J2:10
J2:11
J2:12
J2:13
The engine will be derated.
3510-2
Sensor Supply Voltage 2 : Erratic, Intermittent,
or Incorrect
The Electronic Control Module (ECM) detects a fault in the 5 VDC sensor supply
circuit supplied on the following pins:
J1:14
J1:16
If equipped, the warning lamp will come on. The engine will be derated.
3511-2
Sensor Supply Voltage 3 : Erratic, Intermittent,
or Incorrect
The Electronic Control Module (ECM) detects a fault in the 5 VDC sensor supply
circuit supplied on the following pin:
J1:17
If equipped, the warning lamp will come on.
The following background information is related
to this procedure:
The ECM supplies reg5 VDC to the following
sensors on the J2 connector (a 3509-2 diagnostic
code applies to the 5 VDC supply for these sensors) :
• The position sensor for the intake throttle valve
• The position sensor for the NOx Reduction System
(NRS) valve
• The intake manifold air pressure sensor
• The fuel rail pressure sensor
• The exhaust gas pressure sensor
• The secondary (camshaft) speed/timing sensor
The ECM supplies reg5 VDC to the following
sensors on the J1connector (a 3510-2 diagnostic
code applies to the 5 VDC supply for these sensors) :
• The Diesel Particulate Filter (DPF) differential
pressure sensor
• Analog throttle position sensor 1
The ECM supplies reg5 VDC to analog
throttle position sensor 2 on the J1 connector. A 3511-
2 diagnostic code applies to the 5 VDC supply for this
sensor.
