So speedometer and odometer they are not working. Really need that to drive everyday. After doing some research already here are the facts. The fault code is 1234 speedometer A signal malfunction. Already tested to see if the instrument cluster is working. It is. Now for the question. Where is this sensor located is it the sensors in the wheels that measure speed or is it the one in the back of the differential. Any diagrams showing the sensor location or voltage readings for the sensor would help a lot. Thanks

Vehicle speed sensor is in the back of the diff. 2 small bolts hold it in. The wheel located sensors are for ABS.
Check the wiring to make sure the connector is clean and the wires aren't frayed. Pull the sensor out, clean any metal shavings off the prongs and reinstall it.
They're not expensive, so it may be worth it to try a new one if cleaning things up doesn't solve your problem.
