If there is something wrong with the ECU, it may no longer be able to send the speed telemetry to the instrument panel.

ECUвЂ“ Your PreludeвЂ™s Engine Control Unit (ECU for short) is the computer that takes all of the information that the vehicle sensors compile and uses it to control the vehicle systems, and sends important vehicular telemetry data to the driver via the instrument cluster.

HereвЂ™s a great guide on how to diagnose a wiring short in almost any vehicle If it has, just be aware that it will eventually blow again without addressing the cause of the problem. ItвЂ™s worth checking to see if the fuse has blown. This will often manifest itself after driving through heavy water. Wiring IssuesвЂ“ Exposed wiring to or from the VSS can cause your PreludeвЂ™s speedometer to no longer work.If you donвЂ™t have a scanner, take it to the local parts store and have them run it for you. If the service engine soon light is on, then check the trouble code with an OBDII scanner. The speed sensor does more than just control the speedometer, it also helps to control the cruise control system and may even affect the way that the engine runs. VSSвЂ“ A faulty speed sensor will often be accompanied by the P0500В (VSS circuit malfunction) trouble code.The causes of a bad speedometer will typically be found in these four things: A typical VSS It combines this data to send the speed reading to the instrument cluster. The ECU is programmed with your PreludeвЂ™s gear ratios and stock tire height.

Speedometer Not Working Causes: Honda PreludeДЄ modern vehicleвЂ™s speedometer takes the input from the Vehicle Speed Sensor and sends that data to the ECU. The VSS is one part of a system of sensors that helps keep you safe (traction control, ABS, cruise control). Instead of this direct connection, a modern vehicle uses the vehicle speed sensor and relays that information to the speedometer. There was a physical/mechanical connection between the drivetrain and the speedometer. Vehicles used to use a cable that would usually run from the tail shaft of the transmission to the speedometer. The VSS is usually not very expensive, and they are not that difficult to replace.

If your Honda PreludeвЂ™s speedometer is not working, itвЂ™s usually going to be caused by an issue with the VSS (vehicle speed sensor), or a bad ECU.

You donвЂ™t really realize how much you look at the thing until itвЂ™s just always sitting at 0 MPH while driving down the road. One of the most inconvenient things that can happen to your Prelude is when the speedometer stops working.
