First thing I'd do is check the 5v is good - and steady. Since you seem to have a problem on all, unplug the CTS if it is easy to get at, and measure the 5v to ground there.

Additionally, I would unplug all those sensors, and then measure the 5V at one harness connector (like the CTS mentioned). If the 5V is OK like that, then reconnect each sensor, one-by-one, and see if/when the 5V becomes flaky. If the 5V is not OK with all sensors unplugged, then you need to disconnect the harness from the MS and check for 5V at its output pin; essentially "bench-testing" the MS, probably easier to remove it from the car for this.
