Check Engine Light Due to Code P1423 on Lexus LS600h

The Check Engine Light may illuminate with a code P1423 stored as a result of a large evap system leak. Our technicians tell us this is often caused by a poor seal between the gas cap and the filler neck, revised parts are available to correct this concern.
