stasiu posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Hello, The oil pressure gauge is still not working in my 03 c2 after replacement of the sending unit. Few weeks ago the gauge started go going in and out - showing correct pressure, then dropping to 0, then correct pressure and so on... Recently it stopped showing anything and stays at 0, so I replaced the sending unit, but it didnt help. Now i'm guessing there's a short somewhere in a wiring, but need help troubleshooting it. Here's what I know so far: -resistance values are completely out of range of expected values -there is continuity on both wires from sender unit to the instrument cluster -I measured voltage at the plug behind drivers seat and here are the values: Ignition off: +5V, ignition on: -7V, engine on: -9V. This makes me think that when the ignition is on, it causes 12/14V to flow in the opposite direction to the +5V. -I have piwis scanner and tested the instrument cluster - gauge works Any ideas on how to troubleshoot it further? Seems to me that there must be a short somewhere between instrument cluster and the plug behind driver's seat. Does anybody know if the voltage is supposed to stay at 5V at all times? Thanks, Patrick
