Yes, because normal oil pressure will be between about 8 psi to 14 psi at idle, to about 55-70 psi at highway speed, depending on engine temp and RPMs.
They said I now have 70psi at 3kDid they give you a hot idle pressure value? If the pressure is above 4 psi at hot idle, the instrument cluster is probably the only thing left to replace. If the cluster is a CCN module, it may not be plug n' play. A used or an exchange cluster would have to be configured to your VIN in order to play nice with the other modules.
The gauges are designed to have a wide middle range, so they really aren't accurate, just more assuring to the operator.
Can I just run a mechanical and poopies can the sensor?Honestly, if it is the gauge/gauge cluster failing, rather than the cost and hassle of replacing, for accuracy and peace of mid, I would find a way to tee in an adapter where the oil pressure sensor is located and hookup a manual oil pressure gauge.
You're correct.I was thinking last night that since the cluster gauge driver can position the gauge pointer at the correct points during the self-test, that the cluster itself may be OK?
