One problem related to crankshaft position sensor has been reported for the 1997 Dodge Grand Caravan. The most recently reported issues are listed below.
My van will shut off and come back on without warning so long as your foot is on the gas. If you are coming to a stop it will shut down completely but will restart. The check engine light will come on and immediately go back out with no codes stored. The crank and cam sensor have both been replace by the dealer but didn't solve the problem. This is dangerous when going into a corner or through an intersection when it completely shuts down. This started in 2006 and is still going on.
