Troubleshooting

• 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 regulated +5 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 regulated +5 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.
