Hello While checking codes, P1189 is current; anyone ever get this code? It has something to do with the oil pressure switch circuit? 2000 STS. Thanks for the help.

Found the problem, the connection to the oil pressure switch had become loose. Not bad for the system to tell me that the circuit was at fault and sure enough the circuit was not complete.
