Charcoal Canister

By Daniel Dillon, July 26, 2009

In order to prevent fuel vapors from escaping into the atmosphere, a brick of charcoal inside the charcoal canister collects the vapors and later purges them so they can burn in the combustion process.

Symptoms of a Bad or Failing Charcoal Canister

  • Check Engine Light may illuminate
  • Fuel tank may be hard to fill
  • Fuel smell may be noted

Charcoal Canister Related Repair Advice

  • Evaporative system diagnosis can be difficult and trouble codes can be triggered by sensors and components other than the charcoal canister
  • It is not uncommon for bits of charcoal to separate from the charcoal brick inside the canister and cause the canister purge valve to stick in the open or closed position

the matrix and the corolla and others from 04 and newer have this problem, I think that it is a manufacturers defect and there needs to be a RECALL ON THIS PART> AFTER ALL TOYOTA SAYS RIGHT ON THERE WEB SITE THAT THEY ARE ENVIROMENTALLY FRIENDLY AND TAKES PRIDE IN THERE PRODUCTS.
