IAT Sensor Problem Remains...
Sunday, December 18, 2005 4:57 PM
What I read was this post on another forum because I'm at my wits end. I have gone to a mechanic. This is what went down. I made a post about a month ago... HERE... I read the link inside provided by a fellow member and it seems all it says is to change the sensor, I did. Nothing happened. I pulled the fuse for the PCM to reset it and nothing happened. I went then to a mechanic to see if they could diagnose and possibly even supply the IAT Sensor Pigtail for the crappy wires. They didn't have it. I checked online for the pigtail myself and I am completely confused. Here is what I've found.

Pigtail #1

Pigtail #2

WHICH ONE IS IT?? Or did I even find the right one? I'm freaking out, my gas mileage is suffering and my engine is idling funny as hell. Every place I go to, to purchase it in-store has no clue of what I'm talking about or they say I can only get it from GM. I say @!#$ GM way too expensive and they just piss me off anyway. Terrible customer service. I just need the pig tail, the mechanics and I confirmed that it was @!#$ty wiring. I need this crap resolved so I don't feel like I'm hurting my car anymore. It sucks.

Thanks guys, I really appreciate all of your help. Please only respond with hard facts, if you "think" it's right then don't bother. I need to know the part number of the one you'd purchase or the one you have purchased in the past. Thanks again.

If you weren't such a maybe people would respond, who knows, maybe no one knows? Why not go out and look at your connector?

Thanks for the help Lanman... You're the tool, you're the reason I do not and most times will not ask for help on these great forums. Get over yourself. Just cuz your mom thinks your cool doesn't mean you gotta be "that guy" on the internet, ass hat.

You're the one who started to get pissy because you didn't have instant gratification on your answer.

If that's the case, don't ask for help anymore, get off the forums, and do stuff yourself. Also, my mom's dead; she can't exactly think i'm cool.

I bet if you had a little more patience people might respond more favorably. 8 minutes?

The way I see it you have 2 options....1) Put the car back to stock and see if that solves the problem. That will eliminate the possibility of it being the sensor or the wires. 2) If you insist on replacing the plug, GO OUTSIDE AND LOOK to see which one it is. Print the pictures to take with you if you must.

We can lead you in the right direction. We can't DO everything for you.

Now that was hardly necessary. Is the reason that you don't ask for help here that we don't respond in 8 minutes? Get over yourself.

all 96-05 cavaliers use the same plug for the IAT

your links didnt work for me


but in my experience the plug on our cars the wires are to small of gauge and are prone to breaking at the crimp inside the plug

if you tug on the wires as they go into the plug , 1 will most likely stretch and that is the 1 that broke

the replacement GM harness end uses a larger gauge wire

Just for the record, it wasn't 8 minutes... it was 2 days, look at the original post date. Get off your high horses. It was uncalled for to be uncivil and just call someone a tool for no reason. That is something I would do if I were still in High School. Two days and no simple response would be enough for someone to get a little upset, I'm not saying I deserved a response but you think someone would've read it and said something.

Some people just look for an excuse to get on someones case... Maybe I was joking, tongue in cheek. You think more people would be cordial and laugh off the bull$hit.

So what your saying is that if anyone read your post they should have responded, even if they told you that your flux capacitor is gone and you need a new one? But in your first post you said you want the right answer or nothing else.

Some times you are the only one that has had a prob. and no one has come across it before.

I have posted here a few times and had to wait a week or more for a response...but someone always gets back.

Be patient man...someone will answer you. If not, no one knows, then just take it to a mechanic.

In the end its a two wire plug...follow it back to where it joins into the harness and check the continuity of the wires...
I think the whole system should have continuity ie: from one terminal of the plug to the other should read approx 0 ohms on a multi meter. If its not ~0(anything under 500 ohms is 0) than you should check each wire individually. If one says OL on the meter than you know its broken. If this doesn't show that a wire is broken place a resistor in the two terminals of the plug.
about 2.2k ohm should do. That is all the sensor is, its just a resistive element that changes resistance over a varying temp range and tells the computer how much fuel to dump in to the engine.
If this doesn't fix your CEL than there is something way more serious wrong.
