87 ranger 2.3 fuel injected

[chavid]

My friend's truck's intake has a sensor on it that screws into #1 tunnel, the electrical plug faces you looking in at the engine. The threads are approx. 13mm and the wrench to take it off is 1 1/8". Anyways the sensor got broke and I'm not sure what it is to get a replacement. The tip looks like a temp sensor because there's no holes, diodes, etc. on it. Bought a air/intake sensor but the electrical plug doesn't plug in.
Any help would be appreciated.

Could be a knock sensor.

That a pretty good description, but can you get a picture?

If the hole it threads into is a blind hole (doesn't go anywhere, nothing flowing through it) it's a knock sensor (sounds about right from your description), next guess would be coolant temp sensor but they're usually by the #1 or #2 fuel injector

First post, but I've been lurking since I bought a ranger last nov.
It had this problem too... the last guy broke it off by accident during some work.

It's definitely a knock sensor, and I had a hard time finding a junkyard ranger that had one (been looking since nov.) Today I found one on a similar year of 4cyl mustang.

I ran without it the last few months, though I wouldn't recommend it. The timing advance/retard was definitely not working right, and was sometimes hard to start. With it replaced I now have an increase in torque and it no longer sounds like it's going to misfire at higher RPM's

Bought an intake manifold for modding this weekend. They only charged me for the manifold but it came with all the sensors, and I don't need them, so if you want the knock sensor it's yours. (I wouldn't feel right charging for it)

Ah, I don't think I have one of those on the 96 but I will know what it is for future reference...thanks!

That's the knock sensor.
