Having sensors on a bus such as CAN or LIN rather than point to point wired, Is that a good thing or a bad thing. Is it easier to diagnose a bussed sensor or does it make it more complicated. It seems like with a bussed sensor there are much fewer connections and a much smaller harness so that connections are more robust. Also OBD can work much better with bussed sensors but there must be some tradeoffs.
