- I have Checked harness resistance from sensor to main connector. ok
- have checked sensor input voltage, 5v on both sides, at big connector and through the harness to sensor.
- I concluded to replace wheele hub assembly. Problem still persists.
- All other three sensor register a speed on scanner when wheels are rotated.

    Thanks for the advise. It ended up being a faulty new sensor.

    Just trying to refresh my memory, Do the others have 5v at both legs. Which big plug, at the ABS module. Will have to double check at the shop tomorrow. Did you get a 2nd line hub or a top line hub.
