While installing a gooseneck hitch ,I damaged the rear diff abs sensor. I replaced the sensor , but still have the abs and brake warning lights. Code is for open circuit. I checked the wiring diagrams and trouble shooting flow charts from the dodge repair manual, and the wiring checks out ok. When I double checked the new sensor, I got an open reading on my ohm meter. I was expecting 1600-2300 ohms, sense that's what I should see at the abs module between pins 1 and 8 according to the manual. Does anyone know what I should see for a reading across the rear diff speed sensor? Thanks.
