Circuit Description

If this DTC is set, and no misfire is currently present, the vehicle may simply have been run low on fuel. This DTC being present with a properly functioning fuel sender circuit eliminates the need for a lengthy misfire diagnosis. In any case, a misfire must have been detected before this diagnostic runs. Verify that there is an adequate fuel supply in the tank.
