2.3L ('83-'97) Id missing sensors. Help needed

[Eduardo.lodela]

Hello.
I have a 1988 2.3. It was parked for a decade after a major rebuild: we changed pistons, rings, connecting rods, etc. Now I'm working on taking it back to its most glorious time and form. I am checking and testing all the sensors hoping this little truck will be able to pass the smog inspections. But I'm not an expert at all

So... is this the coolant temperature sensor?

I'm not 100% sure since Autozone shows me these two options:

Also, I could not find the air charge temp sensor nowhere 🫠. I found a video on YT of somebody saying it should be here on the intake manifold:

But another guy said there is where the knock sensor should be at.

Any help would be appreciated.

knock sensors weren't used on all versions but yeah I think that's where one would be, I'd ignore it...

The first pic is the gauge sensor, I think the sensor for the computer is in the lower intake manifold by the fuel rail by the #2 injector

On a 2.3l that upper sender is for Oil Pressure, its on the head
Just below it on the Block is the Coolant temp sender, not sensor, sender just for the dash temp gauge
In 1988 both are single wire senders

ACT or IAT air temp sensor is on lower intake runner towards the front, # 1 and #2 cylinders

Thanks a lot! I'll look for those sensors and senders and change them if needed
