What causes emission codes?
Here are Some Possible Causes for an EVAP Code or an EVAP Leak: Missing or loose fuel cap. Evaporative (evap) emission canister or fuel tank leaks. Evaporative (evap) emission system hose leaking.
How much does it cost to replace an evaporative emission system?
The fuel evaporative system (EVAP) controls emission by housing vapors from evaporated fuel and sending them back to the fuel tank to be reused. The cost for EVAP system repair ranges between $200 and $560. The labor alone will cost somewhere between $35 and $140, while parts will run somewhere between $150 and $440.
