These vehicles do not have speedometer cables. There is an Output Speed Sensor mounted on the transmission. That sends electronic data to the powertrain control module PCM and the body control module BCM. The PCM uses the speed data to coordinate shifting. The BCM uses the data to drive the speedometer. It's all digital.


I'm a retired ASE Master/L-1 Technician. I still keep current with the latest automotive technology.

Visit my blog for cool articles and TSB's:

Follow the speedo cable inside eng compartment down to where it connects to the sensor. Unscrew the cable, pull the elec plug, take out the 10mm bolt, pull the sensor. Replace is opposite.

They don't have fuses. The speedometer is controlled by the speed sensor(s) and the temperature gauge is controlled by the coolant temperature sensor.

replace spedo cable. I don't think the 96 Caravan has a cable. It has an electronic sensor but others said replaceing the sensor doesn't solve the problem.

There is no speedometer cable on a 1995 caravan. it is done by a speed sensor on the transmission and digtal data is sent to the computer and the computer then sends the signal to the speedometer. This is the case even when the speedometer looks analog. Likely a bad speedometer is the cause if it does not move as the speed sensor is used for other functions and would trip the "check engine" light if it was bad. the speedometer is part of the instrument cluster and likely you would need to change the whole thing.

You don't need to change anything. Both speed ranges are on speedometer face.

No. The speed signal is electronic.

Most likely the VSS. Vehicle Speed Sensor. It is mounted on the side of the transmission.

If it is an electric speedo it probably is the speed sensor and if it is a manal speedo it is the cable.

there is a speed sensor on your transmission, probably about 15 bucks, and easy to replace, try there, but first check your fuses.

you unplug the old one. And plug in the new one.

The speedometer signal comes from the abs sensor on top of the rear axle.

The crankshaft position sensor on a 2005 dodge caravan is mounted on the top side of the bell-housing.

The speed sensor sends a signal to the speedometer to show the correct speed and it sends a signal to the transmission telling when to shift. If the speed sensor is bad the speedometer will not work and the transmission will not shift correctly.
