2003 Discovery has never had 3 Amigos issues. Recently had Ashcroft ATBs installed front and rear. After, 3 amigos and brake warning light were on but vehicle drove fine. Using a Hawkeye Code reader, when I try to test the ABS system I get a couple of errors; 4044 Sensor RHF. Also Air Gap Too large. Code 4084 Sensor RHF intermittent sensor output and "broken wire."
When I check the valves either front left or front right, wheels rapidly alternate between being locked and free. Ran a test on the shuttle valve and it came back fine. I have the WABCO replacement but haven't installed it yet. Before deferring to shop, I want to replace the ABS right hand front sensor. Does this seem like a good plan? I can get a new one for $119 plus shipping but will have to splice the wiring. Would appreciate being directed to a video or something as I'm having trouble visualizing this. I feel confident the shop likely accidently damaged the sensor but if I can repair it and save the headache of dealing with them, I would like to. Thoughts? Recommendations?
