Knocking noise
Hi guys, I'm new here. I have a 2007 HHR with a 2.2 engine manual transmission 170k miles. I have a moderate knocking noise starting at around 2000 RPM. In my experience, early stage rod knocks are more audible when the excellerator is released abruptly. Any ideas?

No,
and I see no reason for either gauge.
I have driven cars with no oil but normal oil pressure, and what does oil pressure have to do with rod knock?. I've never seen a voltmeter factory installed, ammeters are useless with alternators.
As bad as a code readout on the dash; too much information is bad.

They knock because they wore out, maybe because there was no oil; not because there was no pressure. The oil disappeared a week before, and as stated I have driven cars that showed normal pressure with nothing in the pan.
Oil pressure in modern cars doesn't tell you anything except that the pump is still functioning.
I would rather have an oil level gauge.

If there is no oil pressure, the oil does not get pumped thru the crank to feed the rods & mains, plus the top end.
