What color is the VSS speed sense wire?
When you remove your OEM radio, there are 4 plugs that plug into the radio. Only 2 of the 4 connectors are used with your new aftermarket radio which are the 2 connectors with the larger size pins. The other 2 are not used but the VSS wire is the brown wire located on the larger of the 2 connectors not being used.
Where is the VSS sensor located?
Identification. The vehicle speed sensor, or VSS, is located near the transmission’s output shaft. The specific placement of the sensor allows the sensor to detect, and report, to the engine’s computer through attachment cabling, the rotation and speed of the shaft.
What is the VSS wire?
The vehicle speed sensor, or VSS wire is normally a part of a vehicle’s speedometer array. The VSS wire is used by the vehicle’s cruise control to determine the vehicle’s speed and it sends a series of pulses, anywhere from 800 to just over 1,000 per mile, and sends these pulses only when the car is in motion.
Where is the input and output speed sensor located?
Locate the transmission speed sensors, they’ll be near the front and rear of the transmission housing. Consult the repair manual for your car. Place bucket or oil drain pan underneath the sensor, there will be some oil that drains out.
How do you test a VSS wire?
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.
Can I drive without a speed sensor?
While it’s technically possible to operate your vehicle without a properly functioning vehicle speed sensor, it is strongly discouraged. A faulty VSS can negatively impact multiple aspects of vehicle operation—which is why it’s best to replace a bad speed sensor as soon as possible.
What is the VSS sensor?
Vehicle Speed Sensors The vehicle speed sensor (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 happens when output speed sensor goes bad?
One of the most common signs of a bad speed sensor is abnormal automatic transmission operation. If the VSS is faulty, the transmission may exhibit symptoms such as delayed shifts, hard shifts, and limited gear operation.
What is the difference between an input and output speed sensor?
Transmission input/output sensors calculate the transmission’s actual gear ratio during usage. The first sensor, referred to as the input sensor, monitors the speed of the transmission’s input shaft. The second sensor is the output sensor, which monitors the output shaft speed.
