    Scanner shows oil pressure from 130 to -15 ?

    Hello and thank you for reading. I have a P59 ECM OS is 12579405. I add the channel for oil pressure and with the engine off it reads 130. With the engine at idle it reads -15 and then jumps all over with different RPM. I tried deleting the channel, connected to vehicle, under vehicle did a repoll then I tried adding it back into the channels and the problem was the same.

    Any help would be greatly appreciated.

    I would double check with a different scan tool, if it reads correct numbers then open a support ticket. They can fix this kind of thing but it helps to know first whether it's a vehicle problem or a VCM scanner problem.

    I didn't think that channel ever worked. The engine still runs even if the sensor is unplugged or pegged out on the dash.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
