Not 100% this is exactly the same as yours but should be at least close. It appears as though they share a common power and ground so it should be as simple as checking for voltage at the hot termination and checking the ground against a good ground point on the frame. If you have voltage at the sensor and the ground is good, I'd suspect you have bad sensors.
If you do not have voltage at the sensor, check for voltage at the parking assist module. If you do not have voltage here, I would check for input voltage into the the module. If that is good, I would suspect a bad PAM. If you do have voltage on the output of the PAM to the suspect sensors, you could have a wiring issue between the PAM and those sensors or the sensors are bad.
My guess is you have two bad sensors. It's best to do some troubleshooting first to verify though. Troubleshooting is much less expensive than parts swapping.
