welcome partner !
94 16v. OBD1 car.
53s have 2 meanings, 3:?
1: wrong ECU.
2: EGR thermo probe. disconnected.
3: ecu has corrupted memory (bad ecu, very very bad ecu)
#1 and #2 are related.
calif ecu in fed car or the reverse or the prob wire fell off.
my guess is the JDM has the wrong EGR valve missing the EGR thermoprobe. it has 2 wire sensors.
1994 is the transition year, from no probe to all cars having it, fed/cal in 1995.
the solution is to look at under hood sticker , see calif words?
and for sure ECU partnumber.

the ecu pn must be right, and match EGR.
the 58B90 and 59B30 must have the EGR gt thermoprobe attached or a 10,000 ohm resistor to fool it (for testing only wink wink)
