thanks for the info, do you mean the sensor above the hi temp sensor that controls the fan,or is on the throtel body area,there are no sensors on air box intake.
:confused:

1991-1994 DOHCs, it screws into the bottom of the intake resonator that runs side to side along the radiator support. The bung is right before the tube that enters the bottom left of the airbox.

Just got the sensor it is the same as the one I installed for the fan

Installed the IAT sensor ,All looked ok wire fine new sensor fit fine but still getting the (23) code, is the something I should done when I changed the sensor? Pull the ground wire on the battery? OR WHAT I'M LOOSING IT WITH THIS P.I.T.A. CAR,also getting crappy mpg any ideas?

anytime you replace a part that creates a code, you want to pull the battery terminal, then turn on lights and hit the brake to make sure all juice in the system is out, then replace terminal. Gas milage being bad could be a variety of things. First clear the computer codes with method above and see if any new codes come up or if same one comes up even.

yes -- need to clear code.

As for crappy gas mileage -- you changed ECTS but did you change the connector too?
It's also possible that ECTS you installed is faulty. What is it's resistance at operating temp?

Failure usually causes the car to run crazy rich = crappy mpg....

The sensor was connected to the tube going to the air box,I also cleared the codes by unhooking the batt., took it for a test drive ,now I am getting a (26) code its being a P.I.T.A again! Please help!!!
connector wire looks like brand new,dont have a meter handy my son has one he's in N.H. for weekend, what resistance should I have when I test it?
One other thing I have what feels like skipping when getting up to speed very slight but is there,not there when at speed?

code 26 = Quad Driver Output Fault. Actually we are making progress. search forum for quad driver as I just explained this in another post recently.

paulsl2 06-27-2009 12:06 PM

I looked for half hour cant find (quad driver output fault) please advise where to find it

cooling fan relay
A/C clutch
Canister purge solenoid
EGR solenoid
Coolant Hot light
Upshift/Shift to D2 light
Speedometer Cutout

If any one (or more) of these have an issue, you'll get a code 26. EGR solenoid and cooling fan relay are most likely and easiest to check.
