Ok, here are my findings. At the the gauge I got 8.4 ohms. I went back to the sensor and checked at the terminals and got the same. Upon starting the car on a cold engine, the ohm reading went up to 25. A blip of the throttle approximately 2000 - 2500 brought the ohms up to about 75. Gauge is still pegged above 5 bar. This was/is a brand new in the box VDO sensor. Ironic that there are two green/red wires going into the gauge from the same loom. Am I reading from the right wire? Checked the other wire at the gauge and found no ohm reading. Pretty sure that I am reading from the right wire as the ohm reading is the same from sensor.
