Not sure which '95 OBD i have but its on the left side of the column, and I have no 'puter on top of my coolant tank (if ya'll need more info i can, those are just the 2 that I know to answer)

Here are my codes:

32 - EGR
35 - IAC
22 - TPS too low
23 - Manifold Air Temp too low
15 - Coolant temp signal high or open (i broke it off )

is there any 1 thing out of that list that would cause it to read all of those? The IAC I just replaced about 3 months ago (cleared the code then) and it is still clean, no guey crap on it. The EGR was replaced before I bought it last june, since then i have had to take it off once a month to clean it (cleared the code then) 22 & 23 I don't understand where to get that info from. its a 1995 4.3L Vortec, 2WD, 2DR.

Any and all input is gladly accepted and needed.

One problem! there is a hole in the bottom of my intake tube about 1/2" before my throttle body/plenum. When I redid my intake manifold gasket 3 months ago, i came up with 1 plugin left with nowhere to go, it was a 2 wire plugin that was short in the loom so it couldn't move around much. I'm assuming that it is used for something and not just a dead end, so.... what am i looking for to go into the bottom of my air tube and plug into that wire??

THANK YOU IN ADVANCE EVERYONE!

That hole sounds like it is for the intake air temperature sensor.

The other things may have a common wiring fault that is causing the codes. If a ground were not proper or the power supplied to the sensors from the ECU was not proper, it could cause these codes to set.

obd 1.... what a crock... LOL

preciate all the input! guess this weekend better be better weather than we've had so I can get this and my cruise control taken care of already!!!

 

$15 freakin dollars for that little sensor.... wow! ......... one thing down, now on to find a ground that is bad, if it is the "power" from the ECU, how would I know or what would I check?
