I hate to beat a dead horse or sound like a broken record, but if all of your electronics are malfunctioning, I'm leaning on the grounds. It sounds like you may have some ground currents going through the sensors and taking them out.
The definition of voltage is the difference of potential. If you have a ground separated by 5' of frame rail, and you measure those points with a very precise ohmmeter, there will be some resistance between those points (difference of potential) simply due to the resistance of the steel. Current is like water, it will take the path of least resistance. This will create problems for those sensors/electronics. Often times loads of current will flow through the one good ground point (sensor ground) and overload the capacity of that ground. Hence, failing a sensor. I know some of this may be hard to believe. Not to toot my own horn, but being an electrical engineer, I've seen some crazy failures due to poor grounding practices. Take a look at the grounds on a modern car. It almost seems ridiculous. There's a reason for that.
Make sure all sensors have a common ground point, and make sure that point connects to battery ground. Don't rely on the chassis as being a good conductor for grounds.
I have my battery grounded to stud I welded to the frame, the engine has the same. I made a conscience effort to land all electronic and gauge grounds to one spot, which also has a large wire back to the battery. It seems like overkill, but I haven't had any problems with sensors not working.
