Kinked, crushed, pinched or collapsed tank vapour line or hose; Blocked or contaminated charcoal canister, or restricted canister connections; Stuck or faulty purge or vent valve restricting flow; Blocked rollover or vapour vent valve in or on the fuel tank; Debris, dirt, rust or insect nests in the vapour line or fittings; Faulty fuel tank pressure sensor giving a false reading; Wiring or connector fault on the EVAP valves or pressure sensor.

How this code is built

P: SystemPowertrain
0: Defined bySAE, the same on every car
0: AreaFuel and air metering, auxiliary emission controls
FE: FaultThe specific fault in that area

What it means

P00FE means the powertrain control module has detected a restriction or blockage in the EVAP tank vapour line, the pipe that carries fuel vapour from the fuel tank towards the charcoal canister. During an EVAP monitor the module saw pressure or vacuum change more slowly than expected, or not at all, which suggests vapour cannot flow freely. The exact monitoring method and line layout vary by model and engine.

Symptoms

Malfunction indicator lamp on
Difficulty refuelling, with the pump nozzle clicking off repeatedly
Fuel smell around the car or fuel filler area
Hissing or vacuum noise when the fuel cap is opened
Slightly poor fuel economy or rough idle in some cases
Failed emissions test due to the EVAP monitor

Possible causes

Kinked, crushed, pinched or collapsed tank vapour line or hoselikely
Blocked or contaminated charcoal canister, or restricted canister connectionslikely
Stuck or faulty purge or vent valve restricting flowpossible
Blocked rollover or vapour vent valve in or on the fuel tankpossible
Debris, dirt, rust or insect nests in the vapour line or fittingspossible
Faulty fuel tank pressure sensor giving a false readingrare
Wiring or connector fault on the EVAP valves or pressure sensorrare

How to diagnose

Read all stored and pending codes and review the freeze frame data for conditions when the fault set, including fuel level and temperature
Check the fuel cap seal and fit, then note any refuelling problems reported by the driver
Visually inspect the vapour line from tank to canister for kinks, damage, crushing, and loose or damaged quick-release fittings
Inspect connectors and wiring to the purge valve, vent valve and tank pressure sensor for damage, corrosion or water ingress
Check the canister and its vent path for blockage, contamination, liquid fuel or physical damage
Operate the purge and vent valves with a diagnostic scan tool and confirm they open and close properly
Compare the tank pressure sensor reading with expected values at key on and during an EVAP test, following the manufacturer's procedure
Use a smoke machine or pressure and flow test, per manufacturer procedure, to locate the restriction in the line or tank vent valve

How to fix

Straighten, re-route or replace a kinked or damaged vapour line or hose
Replace the charcoal canister if it is blocked, saturated or damaged
Replace a sticking purge or vent valve
Clear or replace a blocked tank vent or rollover valve, which may mean lowering the tank on some models
Clear debris from lines and fittings, and repair damaged connectors or wiring
Replace a faulty tank pressure sensor, then clear the code and confirm the EVAP monitor completes

Can I keep driving?

Low severity

The car is generally safe to drive while you arrange a repair. Avoid ignoring a strong fuel smell or visible fuel leak, and get it checked promptly if either appears.
