When the sensors go bad, the temperature will jump around or in the case of the oil pressure one last year it read 0. I've been using the water temp/fuel press and oil temp/oil press since 2003 and have replaced fuel and oil pressure sensors once and oil temp sensor once.
I would have gone PLX if it was available back then. Last year I got a PLX gauge and two Team Rip EGT sensors, logging thru datalogit. One of the EGT sensors started reading 0 most of the time a couple of months ago. When I went to remove it from the exhaust manifold it feels like its cross threaded so I left it alone for fear of breaking something off in therre right before DGRR. 900 to 1000-F at idle is normal for me (aspec 500R with long runner manifold on small street port).
