My wife has a 2013 Dodge Charger SXT, AWD, V6 with 98,000 miles on it. ABS and traction control lights came on along with "service AWD". Scanned error codes C0031 left rear wheel speed sensor, P1DB6 vehicle speed signal performance, P1915 transmission inhibited remote start and U1412 implausible vehicle speed signal received. I changed the left rear wheel sensor and cleared codes. Test drove the car and it lost power and would not shift between drive, neutral, park and reverse. ABS, traction control and service AWD lights came on again. Had to shut car off, clear codes and restart. Got the car home, I was only a short distance away. Now getting code P215C output shaft speed - wheel speed correlation and C0037 left rear speed sensor signal failure. I have not had any ABS codes. I can't find much information on output speed sensor. It seems to be integrated into a conductor plate? Some of the conductor plates I've found online list 2 sensors on the plate as input sensors, no output sensors. I'm not familiar with this. Any info on output sensor or suggestions of what to check next are appreciated.

Does the car have the 5-speed transmission (NAG1) or the 8-speed transmission (8HP45/845RE). The NAG1 does have two input speed sensors on the conductor plate. There's no output speed sensor, The 8-speed valve body has the TCM (transmission control module) and the TCM has an input speed sensor and an output speed sensor. As far I know P215C-00 only applies to the 8-speed.
P215C-00 is set when the TCM receives a corrupt signal over the CAN-C bus from the ABS module (CAN = controller area network).
P215C is an output shaft speed and wheel speed correlation problem.
Problem could be wiring harness/connectors, ABS internal error or TCM internal error. Given the history of wheel speed sensor codes I would start by checking the condition of the wiring harness/connectors.

The TCM compares the wheel speed information with the OSS signal and sets P215C if there's a correlation problem. To determine root cause you have to test the complete path; which is ...
The wheel speed sensor signals are a direct input to the ABS module. The ABS module sends the wheel speed information over the CAN-C BUS to the TCM.
The Output Shaft Speed (OSS) sensor, which is attached to the transmission valve body, sends the OSS signal directly to the TCM; which also attached to the valve body.
You may need the dealership, or other qualified auto diagnostics shop, to run their diagnostics on the car to isolate the problem. Since you don't have the diagnostic equipment they have you're limited to physical inspection and DTC (diagnostic trouble code) analysis.
There were no OSS codes logged, no ABS internal error codes logged or TCM internal error codes logged ... only wheel speed sensor related codes. Make sure all the wheel speed sensors and wiring harness/connectors are working. Wheel speed sensors are cheaper than replacing the ABS module or the TCM/valve body.
