Check fuel pressure using a fuel pressure gauge. A common cause of P0171 is low fuel pressure. Look for readings in psi—typically between 45 and 60 psi for most Dodge Caravan models. Also inspect for vacuum leaks, as these can affect air-fuel mixture.

Use a fuel pressure gauge—many Dodge Caravan models have a quick-access fitting on the fuel rail. This makes it easy to test without removing hoses or components.
