Code details

Generic OBD-II · P0

System: Fuel / Air
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace fuel delivery components before proving the shutoff valve circuit is complete and controllable.

Symptoms of P0005

Check-engine light on, sometimes with rough or uneven running.
Hesitation, surging, or a noticeable change in fuel economy.
Occasionally hard starting or a smell of unburnt fuel.

Common causes of P0005

A failing or contaminated sensor (MAF, MAP, oxygen or air-fuel sensor).
Intake or vacuum leaks, or an exhaust leak near an upstream sensor.
Wiring, connector, or fuel-delivery problems that skew the reading.

Useful checks before replacing parts

Check fuel shutoff valve A power feed, control circuit, ground, connector condition, resistance, and continuity under load.
Inspect wiring near the fuel tank, pump module, or engine fuel system for corrosion, rubbed insulation, and loose terminals.
Compare valve command with fuel pressure, engine start behavior, stall symptoms, and related fuel delivery codes.
