What are the symptoms of a faulty speed sensor?
What Are The Symptoms Of A Faulty Speed Sensor?
- Inconsistent Speedometer Readings. Most cars depend on signals from the wheel speed sensor to adjust their speedometer readings.
- The Check Engine Light Gets Activated.
- Malfunctioning Cruise Control.
- Harsh Transmission Shifting.
Where is the VSS speed sensor located?
VSS gives the onboard computer information about the vehicle speed. The sensor operates on the principle of the Hall Effect and is usually mounted on the tachometer or in the gearbox.
How do you test for GM VSS?
You can test your VSS to make sure it’s functioning properly by using a device called a multimeter. Start by disconnecting and removing the VSS from your engine so you can test it. You can then connect it to a multimeter and set the multimeter to the AC setting.

What is a VSS speed sensor?
The Vehicle Speed sensor or VSS measures transmission/transaxle output or wheel speed. The ECM uses this information to modify engine functions such as ignition timing, Air/Fuel ratio, transmission shift points, and to initiate diagnostic routines.
What voltage does a wheel speed sensor produce?
between .5 to 1 volt
The sensor should produce between . 5 to 1 volt of AC current. The faster the wheel is spun, the more voltage is produced. Some vehicles will send a DC voltage to the sensor through the ground wire.
What is code P0500 mean?
A P0500 engine code means that your engine control module (ECM) is receiving either incorrect or no signals from the vehicle speed sensor (VSS). Since so many systems rely on accurate speed data to function correctly, you need to get your car inspected by a professional mechanic as soon as possible.
What does a transfer case speed sensor do?
A transmission speed sensor calculates the transmission gear ratio when in use. A car has two speed sensors: the ISS and the OSS, working together to show the transmission data to the car’s powertrain module.
