Kia Tech Tip: New Part Cures EVAP Leaks

This bulletin provides the procedure to replace the Canister Close Valve (CCV) on some 2012- 2017MY Rio (UB) vehicles, produced from June 21, 2011, through March 28, 2016, which may exhibit the engine warning lamp DTCs P0455 and P0456 for an evaporative emission system leak due to the Canister Close Valve (CCV) stuck open.

This bulletin provides the procedure to replace the Canister Close Valve (CCV) on some 2012- 2017MY Rio (UB) vehicles, produced from June 21, 2011, through March 28, 2016, which may exhibit the engine warning lamp DTCs P0455 and P0456 for an evaporative emission system leak due to the Canister Close Valve (CCV) stuck open.

The Canister Close Valve (A) is a separate part from the Fuel Tank Air Filter assembly (B) where it is inserted.

Follow the procedure outlined in this bulletin to replace the CCV with an improved part. Before conducting the procedure, verify that the vehicle is within the affected production date range.

The rubber seal material has changed from black to tan.

An engine management system is always trying to find the perfect air/fuel ratio. But it is next to impossible to walk the line between too rich or too lean. With every revolution of the crankshaft, small changes in the air, fuel and operating conditions can cause changes to the oxygen content coming out of the exhaust port.

Oxygen Sensor And Catalyst Efficiency

The catalyst efficiency monitor verifies that the catalytic converter is operating at a high enough efficiency rating to keep exhaust emissions within predetermined values. The PCM compares the signals from the upstream and downstream oxygen sensors to determine the state of the converter. These “tests” are called the readiness monitors.
