Cause
Additional diagnostic information for vehicles equipped with a common rail fuel system
engine logging P009B-13.
Solution
In addition to P009B-13, the faults listed below may also be triggered by the open
circuit on the Electronic Pressure Relief Valve (EPRV). P009B-13 must be
diagnosed first. Once repaired, the problem must be verified to still exist before
troubleshooting any of these other fault codes.

Inspection
1. Visually inspect wiring, connectors, pins, terminals, etc. from Engine Control Module
(EMS) Connector EA (Pins 17 & 18) through the VC1 Connector (Pins 8 & 9), to the
connector at the ERPV.
2. Using a Digital Volt Ohm Meter (DVOM), measure resistance between the pins below. Expe
cted resistance is <1.0 ohm.
- Between EA:17 and VCI 1:8
- Between EA:18 and VCI 1:9
Repair
- If an open circuit or high resistance is found: Make necessary repairs.
- If no issues are identified: Replace the EPRV and the front internal engine harness.
- For all repairs: Apply Permatex Dielectric Grease part no. 81150 or 22058 to the pin and
socket terminals of the EPRV and harness connector. The grease may be sourced locally.
