Where is the VSS located on a car?
The VSS is connected to a speedometer cable and positioned between the axle and the wheel of a vehicle. One of the most common types of VSS operates from a magnet that is also connected at the back of the transmission housing behind the speedometer.
How much does it cost to replace a speed sensor?
After an OBD II scan you learn that your input or output vehicle speed sensor (VSS) has malfunctioned and needs to be replaced. You can take your car to the repair shop or dealership and spend between $100 and $250 or more to have one speed sensor replaced or you can replace the sensor yourself for a fraction of the cost.
Where are the different types of VSS sensors located?
As demonstrated in figure 1, there are two types of VSS: A Hall Effect VSS; A Reed switch-type VSS; Hall Effect VSS. This type of sensor is located on the differential gear housing and monitors the output speed of the transaxle. On average, these sensors have 12-volts of sensor power.
Can a transmission speed sensor be replaced at the same time?
The same removal and installation instructions apply for both the input and output speed sensor. CAUTION: When replacing the new speed sensor be sure the O-ring on the new sensor is correctly fitted on the sensor before installation. Note: Input and output speed sensors are not interchangeable.
What should resistance be for VSS speed sensor?
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. Vehicle Speed Sensor Replacement REMOVAL & INSTALLATION(older models)
Why is my speedometer still a mechanical unit?
The emissions programming can cause a manual transmission vehicle to stall out while decelerating if no VSS is used. The speedometer was still a mechanical unit because the VSS still turned a cable going to the speedometer.
How is the VSS sensor used in the PCM?
OPERATION The Vehicle Speed (VSS) Sensor input is used by the PCM to determine vehicle speed. The VSS generates a signal that increases in frequency proportionate to vehicle speed. The PCM has a base frequency stored in memory for a distance of one mile.
Where is the speed sensor buffer vssb located?
I replaced the vehicle speed sensor VSS then unplugged the vehicle speed sensor buffer VSSB (a 3 inch square flat white plastic sensor box) located behind the glove box, I unplugged it and waited 5 minutes before plugging it back in. I also pulled the brake fuse and did the same thing, waited 5 minutes then plugged the fuse back in.
