Where can I find the speed sensor on a 2008 Nissan Sentra?

In the 2008 Nissan Sentra, the vehicle speed sensor can be found at the back of the longitudinal mount on the transmission's output shaft. Accessing it is most convenient from underneath the car. You'll require either a jack or car ramps, a 10mm socket, ratchet, and extension, along with a 1/4" socket and ratchet drive. Using a 4" flexible ratchet extension can make removing the bolts much easier. If you opt to have a professional perform this service, it typically ranges between $280 and $300, with labor costs making up around $70 to $90 of the total. Signs of a malfunctioning vehicle speed sensor in the Sentra may include the check engine light turning on, rough shifting, loss of cruise control function, loud noises when changing gears, hesitation, erratic speedometer readings, and occasional transmission jerking.
