My first guess would be the starter selinoid. No, I don't know where it is in your vehicle. Follow the big wire back from the starter to find it. You're going to need a test light for this. Make sure there's power on the "battery" side of the selinoid, if YES, make sure there's power on the "starter" side when the key is turned to start. If NO, replace the selinoid - If YES, make sure there's power to the starter, if YES, replace the starter.
parking brake on.
Leave it turned off.... doh
The most likely cause would be low fluid level.
It can cause it to only have second and reverse gears.
it could either be a bad beattery or a bad starter
The light will reset itself when the cause of the code has been repaired.
That is information that the car companies will not release.
Well a lot of them have the same engines & transmissions; but if you have a lot of people you'll be driving around, you'd want the grand caravan...The only difference is the length. I would go with the standard size, it'll probably get better gas mileage and cause less wear on the transmission & engine.
the wheel has to get changed you ediot
It might be that your pcv valve is plugged or the egr valve is sticking.
I had the same thing on my 2002 caravan sport and I changed the caliper, rotor, and pads and no more clicking.
Most likely the VSS. Vehicle Speed Sensor. It is mounted on the side of the transmission.
