Unable to Bleed Up Fuel Tank Vacuum

on 2010 Mazda CX-7 2.5L I4 · AWD

What this code means

The EVAP system has detected excessive vacuum in the fuel tank that cannot be relieved. The system is unable to bleed off tank vacuum, which can be caused by a stuck vent solenoid or restricted EVAP hoses.

Symptoms

  • Difficulty refueling
  • Slow fuel fill at pump
  • Hard starts after refueling
  • Possible stalling

Common causes

  • Canister vent solenoid stuck closed
  • EVAP purge valve stuck open
  • Kinked or collapsed EVAP hose
  • Fuel filler cap stuck or defective
  • Blocked canister vent filter

Diagnostic steps

  1. Check fuel tank pressure sensor reading
  2. Inspect canister vent solenoid operation
  3. Check purge valve operation
  4. Inspect all EVAP hoses for kinks or collapse
  5. Check gas cap or capless filler

Repair notes

Replace the canister vent solenoid if stuck closed; inspect EVAP hoses for kinks.
