If you think it is noise, you'll need a oscope to see how much noise is on pwr and gnd signal. If there is alot of noise, you'll need to make better pwr and gnd connections.

Make sure you chech continuity on the sensor signals, and check their ohmage carefully. You also may have a faulty sensor. It should read some specific ohmage, you'll need a Bentley manual to get that spec.
