Code 23 questions

[fixkick]

sure, and confusing,
that is correct 92/93, some have no IAT, nor a harness to fit it.
if you get code 23, its no lie. the ecu does no lie to you.

23 means its missing , or wires cut to it.
the IAT does not do much on any 16v , its mostly to comply with CALIF ARB laws...
the MAF already measure air temps and does all the 99.9% fine tuning so thus no IAT.
so wire in a resistor. 1000 ohms (need no be exactly) this is 100f tad more. than that. and it runs
or get a 92/93 ECU.
you must have used 95 ECU.
what transmission, 4wd ? or 2wd?
or changed harnesses.
i dont know what you did, what was changed, in details.
ECU, engine yes, harness? or just lost the air cleaner box and iAT port on side.????

the 58B30 ecu has no IAT nor code 23.
per my page
http://www.fixkick.com/ECU/EPC-ECU96-98/...9-95NA.pdf

as you can see the calif 93 has the IAT. first usage 92. there. and then standardized in 1994/95 up.

if all you want to do is fool ECU say so
or get it working with ECU due to smog testing.
in calif if they see custom air cleaner box and missing IAT you fail... see?
i need all the facts here to know what you need.
smog
transmssion
4wd
and current eCU p/n.

and what you want.

cheers ! thanks for posting.
