hello and good morning.
58B30 is listed as E3 (fed only) and these cars have no IAT sensor on Air cleaner case.
the hood sticker shows,a federal only cars.
why does it have a wire here.?
so b17 why red-green wire is populated on a Fed only car, this is odd. why would fed car have a calif harness. very odd.
answer?
Your ECU is expecting a calif EGR for some odd reason.. is my new guess. (even though the p/n lists E3 fed only, )
my guess is there is some load on the red-green wire, or expects one.
shocking fact about that B17 reg-green wire is there. (thanks for photo proof. wow)
so now we do 2 more checks.
1: see if that red-green wire makes it to the back of engine on a 2 pin connector near EGR. (you told me there is no calif, egr there ,but there must be a connector, my guess)
1a: if the wire is there , connect a 10,000 ohm resistor to it, 53s gone.
1b: if the wire is not, in the bay, we can cut this wire say 6 inches from ECU and see of code 53 stops or add a resistor.
the suzuki parts list states there is no themoprobes on Fed 93 Sidekicks,, its very clear. i snap a photo of that.
but forget that now, we do the proof testing.
b17 shows battery, this means there are no shorts or loads on that wire, that pin has a +12v battery pull up resistor on that pin, and if there was a load, the pin voltage is way lower.

53 means resistor missing, 12.6v, reading (DMM) means it is missing. the EGRT.
guess 2
resistor, if your ECU is smarter, (nah,) is a 100,000 (100k) resistor (winter temp) might end 53s and startup 51s. (CAL style)
the Calif ecu can actually measure that the thermistor is missing, my guess, over say 500k ohms? tricky it is.
what i dont know is if some FED ecu's SCAN for Calif ,parts. in later, 1993 cars...
here are the rules for this pin: B17 called EGRT.
Data Points (factory spec) for the EGRT: source Pg, 6E99 FSM. ( has a graph plot and test procedure)
