Q: What voltage should your output sensor be at?

asked by on July 30, 2017

My output shaft speed sensor was jumping around on voltage plus the ground wire was too.
My car has an automatic transmission.

The speed sensor will output less than 1.5 volts since it is a voltage generator and will vary with vehicle speed. If speed output is erratic then you may have to replace the sensor and then see if readings are steady with speed.
