P0005 medium Severity

P0005: Fuel Shutoff Valve A Control Circuit/Open

May cause no-start condition, stalling, loss of power, rough running, and illuminated MIL

Overview

OBD-II DTC P0005 indicates an open or malfunctioning control circuit for the fuel shutoff valve 'A', often due to wiring issues, faulty valve, or ECM/PCM problems affecting fuel supply.

Common Symptoms

  • Check Engine Light (MIL) illuminated
  • Engine cranks but may not start
  • Engine stalls or runs poorly
  • Reduced engine performance
  • Intermittent loss of power

Most Common Causes

Open or damaged wiring harness in fuel shutoff valve control circuit high

Breaks, corrosion, loose pins, or insulation damage interrupt signal to the valve

Faulty fuel shutoff valve A high

Valve coil failure or stuck mechanism prevents proper fuel control

Faulty ECM/PCM output to control circuit medium

Driver transistor failure or software issue may mimic open circuit

Fuse or relay failure in fuel shutoff valve circuit medium

Loss of power supply to valve can trigger code

Poor ground or connector contact medium

Corroded or loose ground can mimic open circuit symptoms

Diagnostic Steps

  1. Connect professional OBD-II scanner and confirm P0005 is current and note freeze frame data
    Expected: P0005 present, possible other fuel system codes
    Interpretation: Verifies code validity and context
  2. Visually inspect wiring and connectors to fuel shutoff valve A
    Expected: Check for broken wires, corrosion, loose connectors
    Interpretation: Physical damage often correlates to open circuit
  3. Use multimeter to measure continuity and resistance across valve control circuit
    Expected: Resistance within manufacturer spec and continuity present
    Interpretation: Open circuit indicates wiring or valve failure
  4. Apply power and ground at valve to test activation and check fuel pressure response
    Expected: Valve actuates and fuel pressure rises
    Interpretation: No actuation suggests valve or ECM driver fault
  5. Check fuses and relays related to fuel shutoff valve circuit
    Expected: Fuses intact and relay operates correctly
    Interpretation: Blown fuse or bad relay can mimic open circuit

Repair Solutions

Repair or replace damaged wiring/connectors in fuel shutoff valve circuit medium
Estimated Cost: $50 - $300

Fixing wiring often resolves the code if no component is faulty

Replace faulty fuel shutoff valve A medium
Estimated Cost: $150 - $400

Part cost varies with model; required if valve fails resistance or actuation tests

Replace or reprogram ECM/PCM if internal driver circuit is faulty hard
Estimated Cost: $500 - $1500

Only after exhaustive electrical tests rule out external causes

Replace related fuse or relay easy
Estimated Cost: $10 - $100

Simple check that can quickly eliminate power supply issues

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Incorrectly replacing fuel pump or injectors without verifying valve circuit
  • Assuming ECM failure without ruling out wiring/connectors

Frequently Asked Questions

What is the definition of the P0005 engine code?

The P0005 code stands for Fuel Shutoff Valve A Control Circuit/Open. This generally indicates an issue with the Fuel System system.

Can P0005 cause engine damage?

You should treat P0005 as a medium issue. May cause no-start condition, stalling, loss of power, rough running, and illuminated MIL

How do I know if I have code P0005?

You may experience the following: Check Engine Light (MIL) illuminated, Engine cranks but may not start, Engine stalls or runs poorly.

Why is my car throwing a P0005 code?

It can be caused by several factors, most notably: Open or damaged wiring harness in fuel shutoff valve control circuit, Faulty fuel shutoff valve A, Faulty ECM/PCM output to control circuit.

What is the price difference for fixing P0005?

Expect to pay around $100 if the issue is a Replace related fuse or relay, but up to $1500 if the Replace or reprogram ECM/PCM if internal driver circuit is faulty needs replacement.

Does P0005 affect Ford, Toyota, or Honda?

P0005 is not specific to any one brand. It can appear on Ford, Dodge, Toyota, Honda, Jeep, and other vehicles.
