How to fix trouble codes P0455, P0456 Acura

Acura has issued a service bulletin 14-006 to address trouble codes P0455, P0456 Acura. The bulletin applies to the vehicles listed below with the listed VIN ranges. In these vehicle the Check Engine light may come on and the ECM stores trouble codes P0455, P0456.

P0455 (EVAP system large leak)

P0456 (EVAP system very small leak detected)

In addition, the gas cap may be loose or stick/slip when you try to tighten it. Acura has determined that the gas cap gasket is creating too much friction and prevents the cap from sealing properly. Acura has issued revised gas caps for these vehicles. See the parts list below. The old gas cap has a black gasket, while the new cap has a brown gasket. If the gasket on your vehicle is brown, it has already been updated and the problem is not related to the gas cap.
