What are the differences in Vehicle Speed Sensor configurations between the FN4A-EL and FS5A-EL transaxles, and how do you replace the Vehicle Speed Sensors (VSS) and other sensors on Mazda 3?

The FN4A-EL ( 4-speed ) transaxle has two speed sensors an Input Turbine Speed Sensor ( TSS ), mounted on top and a Vehicle Speed Sensor ( VSS ) mounted towards the lower right rear. On the contrary, the FS5A-EL (5-speed) transaxle has three speed sensors: the Intermediate Shaft Speed (ISS) sensor and the TSS at the top, and the VSS is also located at the bottom left rear. Replacement To remove and install the VSS, place the vehicle on jackstands, loosen the engine under-cover, unhook the electrical connector, and detach the mounting bolt to remove the VSS, and discard the old O-ring and use a new one during installation. In other sensors, disconnect the negative battery terminal, battery, battery tray, upper engine cover, electrical connector with the sensor, mounting bolt, and sensor and again discard the old O-ring and replace it with a new one. The single speed sensor is on the top of the manual transaxle.

How to replace Vehicle Speed Sensors in manual and automatic transaxles on Mazda 6?

In the case of the manual transaxle, the Vehicle Speed Sensor (VSS) is located in the upper right corner of the transaxle and above the inner CV joint of the right drive axle. In order to remove it, jack up the vehicle and place it on jack stands and then dislodge the engine cover. Unscrew the VSS and electrical connector to VSS, dismount the mounting bolt, and pull out the VSS. Installation involves the use of a new O-ring that is discarded when old and installation is the reverse of removal. When it comes to the automatic transaxle, all other models (except the AW6A-EL and AY6A-EL or 6-speed) the speed sensors are part of the transaxle assembly and cannot be accessed by the home user. It has three speed sensors which include the Intermediate Shaft Speed (ISS) sensor, the Turbine Shaft Speed (TSS) sensor and the Output Shaft Speed (OSS) sensor. The sensors of the ISS and TSS are positioned on the top of the transaxle, and ISS as the rear, and TSS as the forward one. The OSS sensor appears close to the lower-left rear side of the transaxle. In case of replacement of the OSS sensor, raise the vehicle then place it on jackstands and remove the engine under cover. Unscrew the electrical connector of the sensor, unscrew the mounting bolt and detach the sensor. Replace the old O-ring with a new one at installation, the latter has the reverse sequence as removal.

Mazda Vehicle Speed Sensors

The name Mazda vehicle speed sensor itself implies that it tracks your driving velocity or the rotation (how fast) of a wheel. This is done by its detection system, which ensures that when you relieve pressure on a wheel, the computer knows about it as we use the Anti-Lock Braking System (ABS). If your odometer does not work; if your speedometer doesn't work or works intermittently; if cruise control doesn't work properly; if transmission shifts are less responsive; if your vehicle idles wrong; if your vehicle vibrates; if your vehicle suddenly loses power; for cars with reduced fuel mileage and when the Check Engine Light is on, these are some of the symptoms that can indicate speed sensor failure. Consequently, owners should frequently check, fix, and replace their speed sensors.

Whenever you need replacements, opt for genuine Mazda Vehicle Speed Sensors. Because they meet the manufacturer's criteria, it guarantees that replacements fit perfectly. Thus, these make better choices for people who care about driving. Why should you shop at MazdaPartsNow.com? We sell genuine Mazda Vehicle Speed Sensors.
