Why is my speedometer not working on my Lincoln Town Car?
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. If your Lincoln Town Car’s speedometer is not working, it’s usually going to be caused by an issue with the VSS (vehicle speed sensor), or a bad ECU.
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).
Why is my speedometer not working on my Aveo?
The causes of a bad speedometer will typically be found in these four things: VSS – A faulty speed sensor will often be accompanied by the P0500 (VSS circuit malfunction) trouble code. 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.
What is the ECU on a Lincoln Town Car?
ECU – Your Town Car’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.
What to do if your Lincoln speedometer is not working?
If your Lincoln Town Car’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. If it doesn’t, it’s time to take a look at it.
Why is my speedometer not working on my Town Car?
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 Town Car’s gear ratios and stock tire height. It combines this data to send the speed reading to the instrument cluster. The causes of a bad speedometer will typically be found in these four things:
