question about code 15 and 22 on my 1992
service manual says code 15 is coolant temp sensor - is there a way to "test for this" without a scan tool?
also, code 22 shows TPS - can i also test this without a scan tool?
i checked the FAQ for stuff - but the 1992 has a non adjustable TPS, so i'm not sure what to do.
any help would be appreciated

i'm just confused - the temp sensors seem to work fine - both the analog and digital guages work - or is this sensor something different?
and where is it located? i'm so confused!?!?!?!?

I agree....change your coolant temp sensor. I also have a 92 and a while back I was having a hesitation problem under acceleration and I got the eng. temp sensor code, changed it out and the problem went away. Good Luck!

and does anyone know where this ECT sensor is? is it in the head? on the pump? the radiator?
thanks for all the input so far

ok, so i have to clarify - as i'm not the smartest!
if the sensor or the piggyback connector were bad, wouldn't the DIGITAL temp guage not work?
i remember when i had some work done a while back, he forgot to plug the connector back on the pump, and my temp registered 130 and never changed.
wouldn't this do the same thing of the ECT was bac?
just curious?

a'ight, that settles it, i'll get a new sensor today and try and get it changed tonight, then reset the codes and see if it goes away.
i heard removing the positive battery terminal would reset codes - and it only must be left off for 30 seconds - is this true?

The Coolant Temp Sensor is very inexpensive and no problem changing it out. They may loose some degree of sensitivity over the years and I replaced mine just 'cause it was there when doing some other work.
I recommend checking a wire diagram for your model year. Just looked at the schematic for my 90(Page 8A-20-1 Electrical Supplement) and the Coolant Temp Sensor and Throttle Position Sensor come together at Splice120, form a single wire, then goes to a ground in the ECM (Electronic Control Module), pin G10. Your wiring and splice numbers are likely different but with two problems at once, I'd check to see if the circuits share connections.
The codes listed should disappear as noted. Some other codes, say ABS, will not.
Good luck with this repair and let us know.

anybody think that's a bad idea?
now - what concerns me is the wiring - good grief, i'm a certified 'parts changer' not a mechanic!
anyone know where i should be looking for a possible wire issue on this thing?

well i threw $9 at it for the ECT and it took all of 10 minutes to replace - and 20 minutes to burp the system - and i think it can still be done some more!
i think i'm gonna throw another $28 at it for the TPS sensor and call it a day - if that doesn't fix it, then i'll be tracking wiring - it looks like both those sensors meet up along with the IAT or whatever it's called as far as wiring goes, so that'll be my next task if this doesn't work.

Seriously Togo....you should invest in a set of Helm manuals for your car. I think that's what CFI-EFI is tactfully eluding to.
There was a set for sale for a 92 over in "parts" awhile back. You might check.
