Output Speed Sensor Circuit No SignalNote: This definition of P0722 is applied to all manufacturers
Most likely you have a defective ABS sensor which is part off the front bearing assembly. you will need have or if you have a code reader capable of reading abs codes find the wheel that is causing the code. Then source the part and if you have the ability to replace it replace it. The code/ light should go out when the abs signal is getting correct information.
did you just the rings on the axles?look at them close sometimes the rings on the axle crack and this causes the abs light,,,,the generic scanner do not communicate with any module but the ecm/pcm they do not read abs only dealer and high $$$ snap on ones do read abs..thats why you can read it,,im sure there is a code but you need then right scanner
The code scanner that you need is called ODBII code reader with ABS, and it works in the same way as the one that you connect to the car computer module (ECU) to read codes when the check engine light comes on, but the cheap ones that you can buy from $50 do not have the ABS brake scan function.
If the problem is the ABS, then it is often a wiring to abs problem, or a defective ABS control module, a scan reading is necessary to know what the problem is.
It may be an ABS sensor... however you'll want to get those ABS codes read. A regular code reader doesn't do that, you'll need a specific ABS code reader or take it to a shop.
First, you have to retrieve ABS code, not Powertrain code.
You are looking in the wrong direction.
When there is a Faulty ABS code the Abs module remove the cruise control function.
After you fix the ABS faulty code and erase code you will have the cruise control back again.
