What does a speedometer cable connect to?
The speedometer cable is connected to the back of the speedometer and runs through the gearbox of today’s modern cars, trucks and SUV’s. The cable is powered by the drive shaft and turns a magnet that creates an electrical current and sends this information to the onboard computer.
How does speedo cable work?
The speedometer cable, powered by the driveshaft, turns as well. The cable spins a magnet around at the same speed inside the speed cup. The magnet rotates continually in the same direction (in this case, counter-clockwise). As the speed cup turns, it turns the pointer up the dial, indicating the car’s speed.
What would cause the speedometer not to work?
The most common causes of a speedometer that stopped working include are a faulty speed sensor, a broken gear on the speedometer, damaged wiring, or a faulty engine control unit.
Where does the speedometer cable go on a car?
The speedometer cable is driven from the gearbox, and curves smoothly up through the engine compartment and the bulkhead to connect with the back of the speedometer. Speedometer failure is likely to be caused by a fault in the cable that runs from the gearbox to the back of the speedometer gauge.
How do you remove the speedometer on a Toyota Corolla?
Wipe the speedometer cable connection with a rag. Use a pair of pliers to pull out the metal horseshoe spring clip that connects the cable to the transmission housing, if so equipped. For the threaded cap design, grip the cap with the pliers, and turn it counterclockwise to unscrew it.
What causes a speedometer to stop working on a car?
Speedometer failure is likely to be caused by a fault in the cable that runs from the gearbox to the back of the speedometer gauge. If the gauge needle does not move at all, the inner cable or drive may be broken; or the cable’s square ends may have become rounded with wear and fail to engage in the sockets.
How do you tighten the speedometer cable on a Honda Accord?
Tighten it with a pair of pliers. For the other design connector, push the cable end into the speedometer housing, and slip the clip back down over the locking groove by hand, or push it into place with the pliers. Use the floor jack to lift the vehicle, and remove all the floor jacks.
