OBD-II fault code

P00FE: EVAP System Tank Vapor Line Restricted/Blocked

What it means

The EVAP tank vapor line is restricted or blocked, limiting vapor flow through that line.

At a glance

  • Usually lights the check-engine light
  • Affects emissions; the car can fail an emissions test

How it works

The EVAP tank vapor line carries fuel vapor from the tank through the emissions-control plumbing. This code indicates that vapor flow through that line is restricted or blocked, which can happen if the line is kinked, contaminated, or obstructed at a connection.

Common causes

Most likely first.

  1. Crushed or kinked tank vapor line
  2. Vapor line blocked by debris or contamination
  3. Restricted connection at the tank or EVAP plumbing

Symptoms

  • Check engine light on

How to diagnose it

  1. Record freeze-frame data and check for related EVAP codes that may help locate the restricted tank vapor path.
  2. Inspect the tank vapor line along its accessible route for crushing, kinks, pinching, or damage.
  3. Check accessible EVAP connections at the tank and plumbing for a blocked or poorly seated connection.
  4. Following the manufacturer's service procedure, test vapor flow through the tank line to confirm where the restriction is.
  5. If the line is clear, inspect connected EVAP plumbing for contamination or a restriction that affects flow through the tank vapor circuit.

Common fixes

  • Reposition a kinked or pinched tank vapor line.
  • Replace a crushed or damaged section of vapor line.
  • Clear contamination from a restricted connection or line using the manufacturer's service procedure.
  • Repair or replace a blocked EVAP connection identified during flow testing.

Can I keep driving?

This fault commonly turns on the check-engine light and affects the emissions-control system, while the code alone does not indicate an immediate drivability problem. Have the restriction repaired soon; if you smell fuel, stop driving and address the leak or vapor problem promptly.

A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together

This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
