Engine Controls - Tests W/Codes: Introduction
NOTE:
The 3.3L is available in 2 models, low-emission model and flex-fuel model. Low-emission model may also be referred to as Low Emission Vehicle (LEV) model and is used for California emission vehicles. Flex-fuel model may also be referred to as Flex-Fuel Vehicle (FFV) model and is used in all vehicles except California emission vehicles. California emission vehicles may be verified by underhood Emission Control label and may be available in other states. Flex-fuel model may be also referred to as an E85 application and may be identified by label attached to inside of gasoline filler door. On flex-fuel models, if test procedure or specification differs from low-emission models, test procedure or specification will be listed separately. If test procedure or specification does not vary, flex-fuel model will be included with low emission model.
To properly diagnose and repair this vehicle, follow DIAGNOSTIC PROCEDURE under SELF-DIAGNOSTIC SYSTEM.
