that is a FED, ECU
so its missing those 2 wires at the EGR main sensor?
or there is a missing wire for a ground on the ECU, the ECUs' some have this extra ground pin
that tells the ECU its either CAL or fed.
the 3 causes (12vdc at ECU at all times, never 10v)
are:
1: corrupted memory, (seems not)
2: EGR sensor missing. B17
3: that dang ground wire on some ECU's , missing or cut. B14
its marked ground, only and is stealthy, it really (fed/cal select)
check these pins, on ecu for missing or damage
does B17 at ecu have a wire??? is it there at all ? or damaged.? or depopulated at B14?

the first calif 16v was 1992 and suffixed with 58B10. your ecu is 100% federal. MT, 1992/1993,
58b30 is listed as. fed ecu.
the thermopobe EGR is listed only for calif 92/93 and 94/95(cal and fed)
i wonder if the FED ECU looks for a calif thermoprobe at boot and if seen throws 53, ive only seen the calif do that trick.
make sure the B17 wire pin on ecu id depulated.
the EPC, (cat) shows that only harness #1 (engine) is unique for calif. than fed, this would be the probe, i guess.
that is why im curious about B16 wire from eCU the rear of engine.
are you 100% sure this is not a hood sticker CALIF car?
100% , B17 is 2nd proof.. if wired it is calif.
the 92 and 93 cars all had calif as an option. with
new ecu and new, harness to match it.
ive never tried fooling with the useless CAL pins on any FED ecu, not me... so...
Your ECU is listed FED E03.
E33 is calif.
if this doesn't find it then we get to look at all pins on ecu and my FSM pinout map
seen here.

unplug 02 sensor , see if 53s go away/
check voltage at B14 and b15, 0volts and at B17 no wire there , if present why is calif harness in FED body?
b15 is ground sense and a short this wire might cause 53's 0volt is good,
