Got a #17 trouble code, which is the left-rear sensor. Test at the 20-pin connector seems appropriate. Manual recommends replacing sensor, but they are expensive. Can you disconnect the right-rear and left-rear and swap their connections, to see if the trouble code moves to the other wheel? ---

What you can probably do, is to swap the sensor left to right, instead of swapping the plugs. ---

That’s what I was thinking, but wasn’t sure if the connectors were the same. I’ll give it a try this weekend. Thanks! ---

I switched the connectors last night,and now have a new code, #15, which is the right rear. So, I’m assuming it’s my left rear sensor that’s bad. They cost about $160 so, I’m thinking about searching salvage yards. ---

I would start with taking it off and cleaning it if you haven’t yet. There could be a bad pin in the connector or a bad coil, or just some dirt/crud built up in the contact area where the sensor picks up the signal from the rotor. THere isn’t much to those things, just a coil and a cogged rotor that creates a microvoltage as the tooth or gear sweeps past the coil. Maybe the bracket got bent? I’m not sure what you switched, but I would try to clean everything and look for proper adjustment before you go buying parts. ---

The other end of the harness has a connector that is located in the middle of the rear axle. Coincidently, the connector for the right sensor is right next to it. So, I switched the right with the left and got a different trouble code. That tells me the problem is in the left rear sensor. I did do some break on the left rear recently so, I’ll take your advice and try cleaning around the sensor area.
