vdo oil pressure

[SDClark]

If you remove the wire from the VDO sensor do you measure ~5volts?

Have you configured your display to use the VDO sensor table settings?

While it appears that this is a new installation, I think the VDO sensors can be flaky. Mine has operated ok for 3 years (no clue if the values have been accurate). Recently, however, the sensor has started intermittently reporting pressure of 100 lb+ when I power up the my 4500 prior to engine start. A minute or so after engine start the pressure drops to reasonable values and stays at reasonable values throughout flights. FWIW, I've also seen, on rare occasion, the VDO fuel pressure sensor peg on power up.
