about last month I had an intermittent signal to right rear sensor and now it’s constant and the code says right rear sensor circuit but I’ve changed the sensor out 3 times and nothings changed. Any ideas on what it could be?

Since you've already replaced the right rear sensor multiple times with no change, the problem could be elsewhere in the circuit. Here are a few things you might want to check:
- Wiring and Connections: Inspect the wiring harness for any signs of damage, corrosion, or loose connections. Sometimes the issue can be as simple as a bad connector or a short in the wire.
- Ground Connection: Make sure that the ground connection related to the ABS system is clean and secure. A poor ground can cause all sorts of electrical issues.
- Module Issues: It’s possible that the ABS module itself is malfunctioning. If other sensors are functioning correctly, the module may not be processing the information from the right rear sensor properly.
- Scan Tool: If you have access to a more advanced scan tool, you might be able to check for additional codes or data that could help isolate the issue.
- Other Components: Sometimes, issues with wheel bearings or other parts of the braking system can cause sensor errors, so it might be worth checking those as well.
I’ve checked the sensor wiring with a multimeter and it gets 12 volts when parked and on. I’ve also replaced the entire axle shaft assembly.
After checking all the codes these are what I got: c102B right rear wheel speed sensor circuit, U1418 implausible right wheel distance
