What happens when the speedometer on a Honda Prelude stops working?
One of the most inconvenient things that can happen to your Prelude is when the speedometer stops working. You don’t really realize how much you look at the thing until it’s just always sitting at 0 MPH while driving down the road.
What to do if your speedometer is not working?
Instrument panel first. If your Honda Prelude’s speedometer is not working, the first place to go would be to check the service engine soon light (if applicable). Now, take it out and see if the cruise control still works. If it does, that’s a pretty good indication that the vehicle speed sensor is just fine.
What is the ECU on a Honda Prelude?
ECU – Your Prelude’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.
How does the speedometer work in a car?
There was a physical/mechanical connection between the drivetrain and the speedometer. Instead of this direct connection, a modern vehicle uses the vehicle speed sensor and relays that information to the speedometer. The VSS is one part of a system of sensors that helps keep you safe (traction control, ABS, cruise control).

Where is the speedometer on a Honda Accord?
It is in the back of the engine compartment on top of the transmission. Remove the air intake hose and filter. Remove the electrical connector on top of the VSS by squeezing the clip and sliding it off of the sensor. Remove the VSS bolt with a 10 mm socket, ratchet, and extension. To remove the VSS, wiggle and pull it straight out.
How does the speedometer work on a Honda Prelude?
A modern vehicle’s speedometer takes the input from the Vehicle Speed Sensor and sends that data to the ECU. The ECU is programmed with your Prelude’s gear ratios and stock tire height. It combines this data to send the speed reading to the instrument cluster.
