G'day fellas, On my 97 pre VVT LS400 I've just finished changing a starter motor, new plugs and leads and a new water temp sensor. Cleaned the intake plenum, intake manifold, ports and throttle body. put it back together and fired her up last night. Everything went perfect except I now have a non operational temp gauge. My question is where to start to diagnose the problem? is the temp gauge signal taken from the water sensor I replaced or from another location. I fitted an OEM water temp sensor # 89422-20010 and DID fit the wiring plug correctly. Your collective thoughts would be greatly appreciated.
Thanks, Little Al.
