codes?

[gc4vette]

any suggestions on how to fix the following codes: 33,123,214,543,and 212. Any help would be great.

I suggest that you visit the EEC test site to see what flashes you are looking for and then run the KOEO test again. You are looking for 3-digit codes. There are a couple of flashes that aren't part of the codes. Go to the "3 digit codes" link at the top of the page referenced above to see the code descriptions.

If the 123, 212 and 214 show up again, you will need a new throttle position sensor (TPS) and a new cylinder identification (CID) sensor.

how much do these sensors cost?

About 50 bucks total from AutoZone.

What if you get no codes.....no all clear codes either on a KOEO test.

 

[projectSHO89]

If you don't get the all clear codes, either there is an error in your testing procedure, or you have either a wiring fault or a problem with the PCM.

Does the CEL illuminate during the lamp test interval when starting the engine?

Yes it does....is that a good thing or bad thing?

I did hear that it is possilble there is a sensor that is causing problems. I was told there are some sensors that only draw 5volts and one of those are locking up the computer for codes.

Does this sound remotley possible?

Check the integrity of the small wire that comes off of the positive battery terminal and its attachment connections. The EEC-IV experts here will probably have a better idea of things to check, I'm not one of them. Check your test jumper connection and make sure it's good and solid. When you do the KOEO test you should hear the fan come on for a few seconds and various solenoids opening and closing for a few seconds.

Bingo!
There is no small wire on my + battery terminal!
Where doese it go to?

 

[Bluto]

Also the fan comes on but no other action or sound happens.
