Transmission wont shift, speedometer not working

217000 km. After starting my van, spedometer stopped working, and my transmission is stuck in 2nd gear, my service light came on. (I read that this is a LIMP mode).
I took out the speed sensors, and on one with a magnet on the end were metal shards, so I cleaned that and hopping that this will solve the problem, but nothing happened. I tried to get a code and it shows code 23 (intake air temp. Sensor voltage low or high) and 55 (should be end of the codes), but as far as I know my engine doesn't have intake air temperature sensor. (3.0L V6 Crysler). I did a instrumentation diagnostic (test) and all gauges all working, the speedometer also. My engine oil is still red. Im still stuck in LIMP mode.
Help please.

Hi Trans has two speed sensors input and output. see figure Faulty output will take out speedo and put trans in limp-in mode. Your van has OBDII go to an Auto Zone have codes read. then post will advise.

1999 Dodge Caravan Automatic

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.

My 99 caravan with the 4 speed auto trans just had the speedo stop working and the trans won't shift out of low. I don't see any obvious line breaks or loose connections. What sensor might affect this and where would it be?

Replace your input and output speed sensors, located on top of the transmission. Both should cost you around $40.

On my dash the speedometer and tachometer do not work. I am unable to get any of the gauges to move while driving. Can you help?

It can be a couple of things, if dash was removed then it may have lost programming for your van so it will not work or the dash is bad and needs rebuilding. Have a mechanic check. Also, check fuses in car. If rebuilt a mechanic will have to reprogram it to your vehicle.

Try unplugging the cluster and plugging it back in again this should correct any bad connections at the cluster.

Please let us know what happens, we are interested to see what it is.

Cheers, Ken

I have a 1998 Dodge Caravan and my son attempted to install a stereo and now my Speedometer and other gauges on the dashboard aren't working. Can you please tell me what I should check to fix this?

There is no ground wire in the van's original harness. Often people will measure the resistance in search of a ground and mistakenly find the dash light or running light wires. Unplug the new radio, then check for a blown fuse.

For what it's worth, I work on a lot of original equipment radios, and there is nothing higher quality than the Chrysler cd / cassette combo radio.

Tried everything you said and took the unit out to examine the soldering on the back of the board. Saw a couple of joints that needed repairing but that didn't fix the problem. The only other thing I can do is order a new one or go to the junk yard and pull one.

Sorry it took so long but I took the board out once more and gave it a good look around. The soldering look good but when I look at the components I found several components that look burnt. The resistors from R11, R34, R38, R36, R40 and JP9 are burnt on both ends. Now I can make out the values of the resistors but the JP9 I have no ideal the value it has just one black band around the center. I'm researching that now, if you have an ideal what I'm talking about please reply if that would solve the problem and the value of that jumper. Thank You

Please help dont need another ticket. Doesn't read speed until about 20 mph. Self chech showed no reading in 1. 2 moved to 50. 3 went back to zero. I just resoldered cluster because gauges weren't working. Bad solder points on back fixed but now speedo doesn't work correct. Did solder something I shouldn't have or do I need to check for more. Any pictures of cluster soldering properly?

Sounds like mr. Cluster has had it!

I just looked on ebay for you.I saw 5 right off of the bat. Ranging from $54 to $150

I did not know the "specifics" of your van so I couldn't get closer
