Trickster, I see all kinds of questions asking about sensors, what they look like, what is this, etc... Can we sticky some of these pics for a reference? If it's not a good idea,, just delete the thread.

I think thats a great idea but you should have labled them also.

The fan switch you posted in pic #1 is broken. So that might not be a good one to use as a reference.

Trickster

I have copied them to my computer and will label them accordingly. Eats5.0's, that is not a bad idea, maybe make a photo gallery of sensors so that board members can search there to see what they look like and get a general idea of there locations

Scott,, I would have labeled them, but I don't know what they all are..

Trickster, if I don't know what they are, I'm sure there are a bunch of newbies that don't either. Not saying I'm a master mech or anything near that,, don't take it that way. If you can, that'd be great..

LAFireboyd, I didn't know it was broken,, you're absolutely right, I wouldn't use that as a reference either..
Thanks fellas..

If you cant stand teh suspense anymore, off the top of my head they are:

1. Fan switch (broken)

2. Knock sensor (also broken)

3. Cool temp sensor for the gauge in the dash

4. FP Pressure switch/oil pressure sender

5. The two in the what looks to be a TPI intake are, I think, the IAT and the CTS for the ECM. Didnt check up on this so I might be wrong...

Trickster

Dimented24x7,

You have identified them all correctly with the exception of the IAT. That is the cold start switch on cars so equipped. Sorry I didn't post the proper names of the sensors earlier. I was working on labeling the pictures to put in a gallery. Thank you dimented24x7 for posting them. The IAT would be under the plenum where the MAT is located on some TPI cars that are so equipped.

Ahhh... guess I know where that is, now. Been a long time since I had a TPI car. No pun intended, but you know what would be trick? If you could compile a tech article that not only had the names of the sensors but did so for the most common f-bodies through the years and showed the location of the sensors for each line of cars. You seem to be quite knowledgable with that stuff... Id definatly like to see that, time permitting for you, of coarse. Most of the off the shelf manuals are crap when it comes to telling where the sensors and such are...

Air_Adam

1 - fan switch
2 - knock sensor
3 - temp sensor (guage)
4 - ?
5 - ?

Should throw in a pic of the O2 sensor too, and the oil pressure sender for the guage.

From what Ive been told, some years/models have the pressure switch (or switch for the 'choke' light) and sender combined into one unit rather then the two like the carb/tbi cars have.

Scottlb9

That one is number 4.

Trickster

In these pictures it is, on other year models it is a different design and there were two parts to it. Here is the oil pressure sending unit and fuel/oil pressure switch that was used on some models.

This is coming out of my 88 IROC, with a 5.7 TPI. I guess I could have been more specific. I have the oil pressure sender (bell) on the rear of the motor, behind the intake. There are two brass fittings that make a 90 degree bend, and then the bell goes in there.

The other half I <b>think</b> will turn off the fuel pump if the oil pressure goes to zero, like in a roll over. I think the sensor is called a oil pressure & fuel pump switch. P/N 25037045. On an 89, it's called a Oil pressure & fuel pump sensor P/N 10096207.

Two people have mentioned my broken sensors,, which makes me feel bad enough,, but here's the other ends of them.. Don't know how I"m gonna fix these ends yet,, or if I even need them with the new motor. Fan switch on left, knock sensor on right..
This makes me think,, when I was going to put in the Hypertech cool fan switch,, I was wondering why it wouldn't go in the hole,,, Stupid me was trying to put it in the knock sensor hole..

ksrammstein

i guess you could get some good conections from a junk yard car then solder them in.


Plus a book like that would be priceless..especially for us newbies and people whose cars have been tampered with by stupid previous owners.

Trickster

Just get the connector you need and replace it on the wire. Don't need to cut and splice or solder if you don't have too.

Next time I go to the boneyard, that's what I'm gonna have to do. I'll make sure I bring the wire cutters. What I meant, was finding third gens is sort of difficult,, but finding one with the wiring harness in tact is downright difficult. Don't know why people want to hack these cars up, unless they are looking for connectors too..lol I totally agree on the book thingy.

Trickster... I could probably manage that, depress the little thingy, and just pull the wire out and replace. I may even have a small enough screwdriver to get in there..

Trickster

Hello Eats5.0's,

I do a lot of wiring on cars from time to time and have gotten a set of the pin insertion and removal tools to help in this process. You can find them at NAPA and some of the other parts stores for a rather reasonable price.

408maro

in pic #1 my engine is missing that(L69) is that also a fan sensor or something on my 305 carb,its gone and the sensor by the front by the alt what is that,cause its there but not connected to anything

Trickster

Hello 408maro,

The item shown in the first picture is a coolant fan switch. The item you are talking about being near the alternator on your 305 carb engine is probably the coolant sensor

408maro

but the coolent sensor is on the thermo. housing,but that switch missing is that a problem

Trickster

Is the item you are talking about in one of these pictures and roughly where in relation to your alternator is this item located? As far as the coolant fan switch missing, according to the information I have on the L69 engine and it may be wrong. There was not a coolant fan switch in that area.
