    I may be wrong, but it is my understanding that there is none. Vehicle speed is acquired from the wheel speed sensors through the ASC-ECU.

    Reference 13A-350 through 13A-351 of the 2015 Mirage service manual. I doubt the 2014 is any different.

    Do you have a check engine light or other problem with the car?

    That's interesting...I may have to test that by unplugging all of my wheel speed sensors and checking if my speedometer fails to operate.

    OK...so here's where it gets confusing for Mirage2014. I assume he has a CVT because he is specifically asking about a transmission speed sensor...which is traditionally associated with an automatic transmission.

    A CVT Mirage has 3 speed sensors:

    1. Primary speed sensor
    2. Secondary speed sensor
    3. Output speed sensor


    The first two sensors are used to control the pulleys inside the transmission. The output speed sensor sends the speed of the transmission output shaft to the computer. I always assumed this is where a CVT Mirage got its speed signal from? But Eggman's service manual reference has me second-guessing that now.

    I've had other cars that when the output speed sensor failed, the computer has no idea how fast the car is going. When this happens, the car shifts poorly (or more likely...the transmission is stuck in "limp" mode) and the speedometer won't work. I'm not 100% certain of this on the Mirage because it has other sensors it may be using (like the wheel speed sensors). This would also explain how a manual transmission Mirage speedometer works...because a manual transmission doesn't have an output speed sensor.

    You can find the location of these CVT sensors by checking the "Component Location" section of the service manual...
