Engine light on - Dodge Grand Caravan Sports 2001

The check engine light came on after a trip. A friend suggested disconnecting the battery. So I did and then light went out for almost 1 year and now back on again. I checked to see what the code was and it now comes back as p1684....so how do i turn it off? And what is the real problem given that the light was on before I disconnected the battery?

P1684 means the battery was disconnected within the last 50 starts!!
this means that the light should go off, if it continues to set that same code i believe it's because the battery voltage is too low!!
so buy a new battery and that should fix your problem!!:-)

How do I install a starter on a 2001 dodge caravan starter?


Lift up the front of your car. Disconnect the (+) cable of the battery. The starter is located in front under vehicle with cylindrical shape. Remove the cable of the starter and solenoid. Remove two bolts that secure starter to engine. Pull the starter to disengage the pinion from the fly wheel.
