Should I connect VSS wire?
Hooking to the vehicle speed sensor (VSS) is only necessary if the stereo unit also has built in navigation software that uses it. Without built in navigation there will be no wire for the VSS.
Is a transmission speed sensor the same as a VSS?
The vehicle speed sensor (VSS) is also commonly referred to as a transmission speed sensor or output shaft speed sensor. The engine and transmission control systems both rely on the data provided by the VSS to make the necessary adjustments for your vehicle to run efficiently.
What is a VSS speed 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 does a VSS speed sensor do?
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.
How do you test a vehicle speed sensor?
Vehicle Speed Sensor Testing Turn the ignition switch to the OFF position. Disengage the wiring harness connector from the VSS. Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (ohmmeter function) between the sensor terminals. If the resistance is 190–250 ohms, the sensor is okay.
What does a bad speed sensor do?
A bad speed sensor most often affects the shifting of the automatic transmission. However, in cars with an onboard computer, the sensor also affects the ABS system , speedometer, cruise control and power steering. Proper diagnosis and repair is essential for safe operation of the car.
What are the symptoms of a bad transmission speed sensor?
Symptoms of a Bad or Failing Transmission Speed Sensor. Common signs include harsh or improper shifting, cruise control not working, and the Check Engine Light coming on. The transmission speed sensors are used to calculate the actual gear ratio of the transmission while in use.
Where is my speed sensor located?
Your vehicle speed sensor is located on the TOP of the transmission on the SMALL end over near where the right axle enters the transmission case.
