Problem Description and Possible Solution
The Check Engine Light may illuminate with code P0442, P0456, and/or P1450. These codes are related to the EVAP system. Our technicians tell us that if no EVAP system faults are confirmed, updated software is available for the powertrain control module (PCM) which should correct this concern.

Check engine light came on with EVAP code coming up. Took it to a pep boys and they came back to me with the canister vent valve needed replaced. One day later the light was back on with along with a surging in the engine. Recharge light blinks in rhythm with the surging. It is now at a ford dealership and they drew up the same code for the EVAP. They haven't pin pointed the issue and said that they need to remove exhaust and fuel tank to check a fuel vapor valve. Issue unresolved as of yet.
