Having problems testing my abs sensors on my 2011 f150. Don't know if they are active or passive style. The sensor identified by code reader is LH front no input. This happened immediately after installing a new hub that came with new sensor. Sensor ohms out the same as others, but will not produce AC mega volts while spinning. Worked fine until I replaced the worn out wheel hub. I do still have the old sensor that was good. But thought I would do some preventive maintaence by putting in a new one. Can anyone tell me the correct procedure to test sensors, and what style ford used. Can you spin the wheel and measure AC voltage like a lot of sensors. Or does ford have a different test. Can find any video for testing these sensor on the f150 2011 and up?
. Would love to have correct procedure for future reference.
Thanks ahead of time.
