2002 Dodge Grand Caravan 3.3
The complaint is an MIL on. The first step to find what causes an MIL is to get the stored trouble code. This one is P0456. A small leak detected in the evaporative system.
Where would you start? You start with an inspection of the gas cap and check the gas cap seal for cracks. Underhood you should inspect the evap hoses for cracks, especially any rubber hoses that fasten to plastic or steel tubing. There, near the throttle body is a small leak in the rubber hose where it fastens to the plastic tube. Under car look for the same sort of cracks. Another hose was cracked near the canister.
It only takes some careful inspection.
