EVAP System Purge Control Valve A Circuit High

36 brands affected · Generic SAE J2012 description.

Key terms: Catalytic converter: cleans the exhaust gases · EGR: exhaust gas recirculation, which cuts harmful gases · EVAP: the system that traps fuel vapour · Oxygen sensor: measures oxygen in the exhaust gas · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

1What it means in plain English

This range covers emissions control (EGR, EVAP, oxygen sensors and the catalytic converter), but some manufacturers also use P04 codes for oil-pressure, brake-fluid and coolant-level warnings.

2Common causes

Clogged or faulty EGR valve
EVAP system leak (hoses, canister, fuel cap)
Faulty oxygen sensor
Ageing catalytic converter
Low oil, brake fluid or coolant (on some models)
Wiring or connector fault

3Can I drive?

Caution · drive with care

Do not assume this code is safe to drive. Check the description: if it names oil pressure, brake fluid, coolant, or a brake fault, stop safely and have it diagnosed before driving. Emissions-only codes (EGR, EVAP, catalyst) should still be checked before an emissions or roadworthiness inspection.

This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
