One thing to understand is crank and cam sensors are usually Hall Effect sensors and do not rely on the reference Voltage being dead on as much as something like an analog sensor like a throttle position sensor.

That being said low reference Voltage could cause a sloppy waveform from the sensor and translate to performance problems. If the reference is low it will likely cause something to play incorrectly.
