Causes

Open or disconnected connector at the fuel shutoff valve
Broken or chafed wiring in the control circuit
Corroded or bent terminals/poor connector contact
Failed fuel shutoff valve (solenoid)
Blown fuse or faulty relay in the fuel/solenoid feed circuit
Poor or missing ground at valve or PCM

Symptoms

Malfunction Indicator Lamp (MIL) on with P0005 stored
Engine cranks but will not start (diesel or systems using a fuel shutoff solenoid)
Intermittent no-start or engine stalls under load
No fuel pressure or loss of fuel flow downstream of shutoff valve
Poor drivability, rough idle, or unexpected engine shutdown

What to check

Read and record freeze frame and any related codes with a scan tool
Visually inspect valve connector and wiring for damage, corrosion, pulled pins, or water ingress
Check fuses and relays related to fuel shutoff/PCM feed
Backprobe valve connector and wiggle wiring while monitoring for intermittent faults
Measure coil resistance of the shutoff solenoid (with harness disconnected) and compare to specification
Measure command voltage/current at valve connector with key ON/engine cranking while command is active

Signal parameters

Control type: ground-switched or 12V-switched (varies by application)
Expected command signal: switches between ~0 V and ~12 V depending on design when PCM commands valve (some systems use PWM)
Coil resistance: typically in the low ohms to tens of ohms (varies by vehicle) — consult vehicle spec
Expected current when energized: often 0.1–2 A depending on coil design (varies)
If PWM used: duty cycle/frequency varies by manufacturer — use dealer/repair manual for exact values

Diagnostic algorithm

Retrieve all codes and freeze-frame data; note related codes (fuel rail pressure, injectors, PCM outputs).
Visually inspect the fuel shutoff valve connector and wiring for corrosion, pin damage, or disconnection.
Check fuses and relays for the fuel/solenoid circuit; replace if defective and retest.
With harness connected, backprobe the control pin and monitor voltage while commanding the valve ON with a scan tool (or during cranking). Record whether the PCM is commanding and what voltage is present.
With ignition OFF disconnect the valve and measure coil resistance between its terminals; compare to specification. High/OL indicates open coil, very low indicates short.
Check continuity between valve power/ground terminals and the PCM/fuse/ground points. Repair any open/shorts found.
If no command from PCM but wiring is good, inspect PCM driver output circuit and related grounds; consult wiring diagram and consider substitution or bench testing if applicable.
To confirm valve operation (bench test), apply vehicle battery voltage momentarily to the valve coil following safe procedures (keep sparks away from fuel). Valve should actuate; if not, replace valve.
After repairs, clear codes and perform functional tests and road test to verify fault does not return.
If wiring and valve test good but no PCM command, consider PCM diagnosis/repair per manufacturer procedures.

Likely causes

Open/disconnected connector or corroded terminals
Broken/chafed wire (pinched at harness, near firewall/hotspot)
Failed fuel shutoff solenoid
Blown fuse/failed relay feeding the solenoid
Poor ground connection at valve or PCM

Fault status

⚠️ Status

P0005 — Fuel Shutoff Valve A Control Circuit/Open: PCM detects an open or non-responsive control circuit to the fuel shutoff (kill) valve; commanded activation not detected.
