Fix ABS light on Dodge Durango
If you have an ABS light on with a 1998-2000 Dodge Durangos, read this. The vehicle gets its speedometer information from the speed sensor located in the rear differential housing. When the computer can’t get a good signal, it sets the ABS light and you get a dead speedometer at low speeds.
First step is to disconnect the connector, remove the sensor,
and check the resistance. It should be 1600-2800 ohms. If it isn’t, replace it with an OEM sensor (NOT aftermarket). These are pretty tight tolerance devices and I’ve seen many brand new aftermarket sensors that don’t make the grade right out of the box. But if you’ve replaced the sensor and it still doesn’t work, then move on to check the connection at the antilock controller.
Unplug the connector and check the sensor resistance between pins 1 and 8 (red/violet and white/violet). The readings should be close to the ones listed above. If they’re not, you’ve got corrosion in the wiring or a bad connection.
Repair the connection and you should be on your way.
