I know holy cow right. I had run the scan tool from autozone a week ago and came up with 3 codes. Replaced the most improtant item. The o2 sensors. The light went away. So, Today I decide to run a real scan tool up to the system, with no light present. So I reset the computer, delete all codes. Take the vehicle out drive it to operating temp, bring it into the shop and I got the following codes.
KOEO codes
67 PNP or clutch switch ckt failure
81 Thermactor Direct bypass
82" "
KOER-60 second test Scan test
12 Can't CTRl RPM
94 CCC/ss4 CKT fault/ Thermactor air inop
44 thermactor air system not working.
I know that 81 82 94 and 44 are all probably indirectly tied together. I'm not sure if the thermactor air system is tied to the pnp circuit? Hell, I'm not even sure what the thermactor air system is.
I was running other codes
I was getting code 81 before which autozones tool said was IAC circuit.
So before resetting Codes I tested my iac solenoid at the tb.
I pulled the Harness to the IAC (two prong) I have more than the 10.5V it calls for KOEO, then it would rapidly drop (Did not test while cranking or vehicle running). I also pulled the Solenoid off the TB and checked it's resistance. The computer told me anywhere between 50-100 ohms is acceptable. If I would check it would jump to somewhere around 53 ohms then would rapidly drop lower down to somewhere around 8-9 ohms. I would take the Ohm meter off. Wait a few seonds and try again. This time it would read around 27 ohms then drop to 8-9 ohms. If I let it sit a for more than 5-6 seconds it would go to around 50-55 then drop rapidly back down. The test instructions did not stat if it would have a continuous resistance of around 50-100 ohms or just a quick resistance and a rapid drop?
