Re: Gauge cluster, oil pressure.
Hi, way back when, maybe before you were born, we used to have to replace the CVR quite often for this type of gauge problems. CVR was short for Cluster Voltage Regulator If the fuel, oil pressure, and temp gauges read high or low, [all of them] It was the CVR. If it was only one gauge, it could be the gauge itself, but most likely a sender problem. Volt or Amp gauges were not controlled by the CVR.
The newer cars have changed the name of this to IVR [Instrument Voltage Regulator] and I think it is called a module now?
