Why does my speedometer keep bouncing between speeds?

Bouncing or jerking of speedometer In cases where the speedometer does not settle on any particular reading but keeps moving between speeds, it is almost always due to bad wiring, in case of a cable system, or a faulty speed sensor. In most cases, only the wiring needs to be changed, or the sensors re-calibrated, to repair the problem.

What happens when the speedometer sensor is not working?

The speedometer sensor is also a critical component in the proper operation of a vehicle’s cruise control. When the sensor is not working correctly, it will not send a signal to the CPU, which impacts the vehicle’s ability to set the throttle for a desired speed.

In this case, you need to add three teeth.

How many teeth are there on a speedometer?

Speedometer driven gears in the Turbo 400 and 700R4 have between 34 and 45 teeth. In these transmissions, each tooth added or deleted changes your speedometer reading. “Each tooth on the driven gear is equivalent to 3 miles per hour,” says Ondra Terry of TCI Automotive.
