This started a week ago with a code I don't remember but it said right wheel speed sensor. Today it escalated to C1331 and C1445. Cleared the codes earlier. In the process now taking the right wheel off unplugging the sensor and checking the connection. I've searched the forum for specifics on how to test the sensor wiring or sensor itself. One member had mentioned he got like 1300 ohms on both his rear sensors in troubleshooting his but never reported back.

Saw the way to remove sensor plug, insert screwdriver in the rear slot of plug. I stopped there to make sure I had it right before going further. Will update in a bit. So assuming there's a sensor bad, I had found a Koyo listing on ebay for $118- Koyo hub pending checking in here thought I'd get some feedback from the good folks here.

edit- Sensor plug looked pristine. I got a 1220 ohm reading across the terminals of the sensor. Have no clue if it's good or bad.

C1445 may be setting as an additional alert because of the wheel speed sensor codes.
If sensor resistance good at sensor then test circuit from the skid control ECU connector to sensor.

Possible that skid control ECU is faulty recognizing the speed sensor but verify sensor/circuit first.

Thanks for the help. Plan to get back to it tomorrow and will start with front left. Watched several videos on it. Will report back. Had I known a week ago I would have further checked the rear right harness.

Pulled the front speed sensor looks like mice chewed the wires right at the plug under the wheel splash guard. Will update after repair.

Unfortunately, looks like I'm going to have to make an educated guess as to which wire goes where as I forgot to notate which wire went in which position of the plug. I'll try to find a wiring diagram.

Edit- found a pic of the connector on an ebay pull, so no worries now.

Installed the repaired harness got rid of the C1331 and C1445 . Still have C1332 code so I guess I'll reexamine the rear sensor and harness.

edit- Had not inserted cable into speed sensor far enough to hear the click of the retainer. Started it and no codes. Still wonder what set the codes to begin with.
