P0455 on Volvo
Evaporative Emission Control System Leak Detected (Gross Leak)
P0455 on Volvo vehicles indicates evaporative emission control system leak detected (gross leak). Au7o has documented this code across 2 Volvo models — most commonly on S60, V70. This code means your car's evaporative emission (EVAP) system has detected a large (gross) leak, so fuel vapors that should be sealed inside the fuel and vapor system are escaping into the atmosphere. The EVAP system captures gasoline vapors from the tank and routes them to the engine to be burned instead of polluting the air, and the computer periodically pressure- or vacuum-tests this sealed system. A gross leak almost always points to something obvious and easy, like a loose, missing, or bad gas cap, rather than a deep mechanical failure. It rarely affects how the car drives, but it should be fixed to pass emissions and stop wasting fuel vapor.
Common Causes of P0455
- •Loose, missing, or improperly tightened gas cap
- •Worn, cracked, or failed gas cap seal
- •Cracked or disconnected EVAP/vapor hose
- •Damaged or missing fuel filler neck seal
- •Faulty EVAP purge valve stuck open
- •Failed EVAP vent valve
- •Cracked or damaged charcoal canister
P0455 on Volvo by Model
Volvo S60(1 issue)
- Fuel Pump Flange Cracking in Hot-Climate States (Recall 09V483000)2001-2004
Volvo recalled 2001-2004 S60 sedans sold or registered in hot-climate states as part of NHTSA campaign 09V483000. On affected cars, long-term exposure to hot climate and repeated temperature cycling, combined with varying fuel quality, can cause the fuel pump flange to develop cracks. A cracked flange lets fuel escape, so the first thing an S60 owner typically notices is a smell of gasoline or a visible fuel leak. In the presence of an ignition source, leaking fuel could result in a fire. The recall applied to S60s in Alabama, Arizona, Arkansas, California, Florida, Georgia, Hawaii, Kentucky, Louisiana, Mississippi, Nevada, New Mexico, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Utah and Virginia, plus the U.S. territories. The campaign as a whole covered 158,733 vehicles across all the Volvo models included, not the S60 alone.
Volvo V70(1 issue)
- V70 Fuel Pump Flange Cracks and Fuel Leak - Safety Recall 09V4830002001-2004
If you own a 2001-2004 V70 wagon that was sold or registered in one of the warm-weather states, it may fall under Volvo safety recall 09V483000. The defect is in the fuel pump flange: over time, hot climate and repeated temperature cycling, together with varying fuel quality, can cause cracks to form in the flange. Fuel then escapes, and Volvo warned that owners may notice a fuel smell and/or a fuel leak. The risk that made this a safety recall rather than a service action is fire - leaking fuel near an ignition source could ignite. The affected states were Alabama, Arizona, Arkansas, California, Florida, Georgia, Hawaii, Kentucky, Louisiana, Mississippi, Nevada, New Mexico, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Utah and Virginia, along with the U.S. territories. Across every Volvo model in the campaign, 158,733 vehicles were covered in total.
