Hello, my name is***** you tell me which gauge is low causing the light to come on?
Thanks. So the check gauges light is coming on but all of the gauges still read fine.
If it registered low oil pressure then I would test the oil pressure sensor or replace it. Does the oil pressure on the gauge match what the TECH II reads?
Thank you. If it registered low oil pressure and turned on the light then you may have a bad oil pressure sensor or an issue with the hydraulic system. I would start by making sure that the oil is fresh and that the oil filter is good. I have had oil filter clog internally and cause this. I have also seen poor connections on the negative battery cable cause this also.
If the voltage in the system is low enough then this will occur. This can occur if there is a bad connection at one of the battery cables or more commonly a bad ignition switch.
It is located on the driver side of the engine block.
The oil pressure sensor on this engine sends it information to the computer who sends it to the gauge.
