Question:

1999 Acura TL Check Engine Light Code P1456

The check engine light came on once after picking my car up from the airport parking lot after sitting there a couple of days and then about 2 months later after having it reset (when my wife was driving it). I just checked at Autozone and they said it was code P1456 . Has anyone had this problem and what did you do to fix it? I'm hoping it was a loose gas cap but wondering how serious a problem it could be and how much I'll have to spend to fix it. Thanks for any help.

  1. P1456 Evaporative Emissions (EVAP) Control System Leakage (Fuel Tank System)

    sounds like it can easy be the gas cap, but to be safe take it in for a check and your local shop.
