hello, i have a check engine light on my 97 grand caravan 3.3 with the electronic 4 sp automatic, codes came up as p1698..no ccd message from tcm and i also got a p0500 no veh speed sensor signal....my prnd21 on the dash has all boxes around them and trans seems to be in limp mode...funnty thing is when i start the van, i have no mileage or prnd21 lit up and no tach,fuel gauge operation...but as soon as i put it in gear..it all comes to life....what gives?...where to start looking?
thanks
