Speed sensor replacement issues in 1999 Dodge Grand Caravan
I recently replaced the speed sensor on my 1999 Dodge Caravan due to the speedometer malfunctioning and the transmission acting up, and ever since I have been having problems. The van won't start, the speedometer doesn't work, and there is a buzzing that doesn't stop unless the battery is disconnected. Any idea what I should do now? Any help would be greatly appreciated.

Re: speed sensor replacement issues in 1999 Dodge Grand...
The buzzing sound is from the torque convertor lock up solenoid,there is a fuse for this under the hood to verify thats the problem from the buzzing,next where did you get the vss,if it's not oem from a dealer than I would think it's the problem also using a obii scan tool check and clear any codes,so as far as not starting is this from a dead battery or other issue I would unhook the vss and see if it can start.

no codes found because your checking the PCM, your problem is you need codes from the TCM,the computer for the transmission,since you replaced the speed sensor the other two things that affect a speedometer and transmission are the input and output sensors,they both screw in the transmission.
On the front of the transmission are 2-speed sensors, Input and Output.
The Output sensor is most likely the culprit. Make sure you check and clean the wires and connection for dirt or corrosion. Sometimes, unplugging the connection and replugging it back in fixes the problem (due to conductivity) but that is rare. Sometimes this sensor has grime all over the inside portion and just needs cleaning, however most of the time this sensor has gone bad and needs the be replaced. It is simple to do: disconnect, screw-out, screw-in the new sensor, reconnect and test. I just replaced mine on my Grand Caravan about a month ago. My Speedometer needle was bouncing up and down and was fixed with the replacement of the Output Sensor.
