* Vehicle Speed Sensor (VSS): This is the most common sensor and provides speed information to the instrument cluster, transmission, and other systems. This is usually located on the transmission case itself. It might be on the top, side, or even the bottom, depending on the year and model.
* Wheel Speed Sensors (WSS): These sensors are located within the hub assemblies of each wheel (one per wheel). They monitor the speed of each individual wheel for ABS and traction control systems.
To determine the *exact* location for your Durango, you NEED to consult your vehicle's repair manual or a reliable online parts diagram specific to your year, make, model, and engine. These diagrams will show you precisely where each sensor is located. Searching online for "[Your Durango Year] Durango speed sensor location" along with images will be helpful.
Replacing the Vehicle Speed Sensor (VSS):
This is a moderately difficult job requiring some mechanical aptitude. Here's a general outline; however, always consult your repair manual for precise instructions specific to your vehicle. Improper replacement can damage your transmission.
1. Disconnect the Battery: This is crucial to prevent electrical shorts.
2. Locate the Sensor: Use your repair manual or online diagrams to pinpoint the VSS on your transmission.
3. Access the Sensor: This often involves removing some undercarriage components, possibly including the transmission skid plate.
4. Disconnect the Electrical Connector: Carefully unplug the sensor's electrical connector.
5. Remove the Sensor: This usually involves unscrewing it. The sensor might be held in place by a bolt, clip, or even a retaining ring. Note how it's mounted for reinstallation.
6. Install the New Sensor: Carefully install the new sensor, ensuring it's properly seated.
7. Reconnect the Electrical Connector: Make sure the connector is securely plugged in.
8. Reassemble: Replace any removed components.
9. Reconnect the Battery: Start the vehicle and check for proper speedometer function.
Replacing Wheel Speed Sensors (WSS):
This is generally an easier job than replacing the VSS.
1. Disconnect the Battery.
2. Remove the Wheel: Use a lug wrench to remove the wheel.
3. Locate the Sensor: It's usually located within the wheel hub assembly, near the ABS tone ring.
4. Disconnect the Electrical Connector: Carefully unplug the sensor.
5. Remove the Sensor: Usually this involves unscrewing the sensor from the hub assembly.
6. Install the New Sensor: Install the new sensor, making sure it seats properly.
7. Reconnect the Electrical Connector.
8. Reinstall the Wheel.
9. Reconnect the Battery.
Disclaimer: Replacing sensors incorrectly can damage your vehicle's systems. If you're not comfortable with automotive repair, it's best to take your Durango to a qualified mechanic. Using the wrong part can also lead to problems. Always use OEM or high-quality replacement parts.
