Speedometer not working

Hi,

Please see the attached procedure for how to test a malfunctioning speedometer. This should walk you through to the route cause.

Please let me know if you have any questions or need more information. Thanks

Hello,

The VSS is located down on the transmission near the axles. Here is a diagram that will show you where it is (below)

DTC P0500: VEHICLE SPEED SENSOR CIRCUIT

Circuit Description

Wheel speed sensors on each wheel deliver an input signal to Anti-Lock Brake System (ABS) Electronic Control Unit (ECU). ABS ECU converts input signals from wheel speed sensors to a 4-pulse input signal to the instrument cluster. Instrument cluster then converts 4-pulse input signal to a rectangular waveform and then sends vehicle speed signal to ECM. On models with Vehicle Skid Control (VSC), ABS ECU may also be referred to as VSC ECU. On models without VSC, ABS ECU may also be referred to as ABS actuator and ECU. DTC is set if there is no vehicle speed signal to ECM while vehicle is being driven. Possible causes are:

Vehicle speed circuit is open or shorted between instrument cluster and ECM.

Defective instrument cluster.

Defective ECM.

Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

Inspect and test the fuses and VSS (Vehicle speed sensor)

Could have another VSS on the speedometer head

Good answer Jessee. There is another problem I have encountered in those vans and that is the ground to the cluster. Check the ground from the battery to the chassis and from battery to the engine. Remove and clean them. The cluster ground is a black wire with a white stripe. Sometimes you can see it on the left side of the passenger compartment screwed into the chassis.

Let me know.

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help.

Please give me the exact code numbers not code descriptions?Codes are starting points notusually replace this or that.
