2005 CTS-V Stealth Gray stock (unmodded and happy this way)
Is anyone experiencing this? I'm at my wit's end other than getting a new sensor. My oil pressure gauge reads either ----- (no reading) or 128 or 129 (max reading). This indicates to me the sensor is alternately full closed or full open. There is no variable reading. I can think of only two issues that might cause this. 1. bad sensor or 2. grounding issue. And I know I have those... Anybody have any ideas?
