When looking around I get the above name more often.

Such as this


With the black one looking very similar to the one I'm looking for
Yep, that black one is what you're looking for. It's referred to as any combo of those terms, we'll call it the CSI thermo-time switch just to be on the safe side, K? It's really expensive as you probably just learned so if I were you, I'd test it to make sure it's really no good. The testing procedure is outlined really well on the 22reperformance.com website. I think it involves heating a pot of water and testing with a multimeter at a cold temp and then hot. Your cold start injector could also be clogged, and is cheaper than the thermo time switch, so be sure before you throw over $100 at it.

Very vague question...
Does anyone know where this goes?




Also, can someone double check the following codes displayed in this video

https://www.youtube.com/watch?v=TUg0...ature=youtu.be

I have the following codes: 24, 31, 42, 51, and 52

Is this correct?

That looks like the distributor hold-down bolt. That thick washer prevents the distributor from rotating which would change your timing. When you put that bolt in, be sure to use rtv or threadlocker to prevent an oil leak. It's one of 3 bolts on a 22re that require sealant.

I have an earlier ecu than you so I'm not familiar with those codes, but yeah the numbers look right to me.

I took a look at what the codes meant out of curiosity and you either have a handful of bad sensors, or much more likely some faulty wiring. Check each sensor with a multimeter to see if it's getting power. If not, you'll have to trace a wiring diagram, physically locate the wires-in-question and visually check for corrosion, breaks or damaged insulation. Also likely is that the damage all occurred at the same place. What a pain, glad I have an '85!

I do agree with you on the sensor wiring.

I am familiar with that bolt on the distributor.
Could you tell me the other two locations you mentioned?

The top-most oil pump bolt needs sealant. The other one is the right-most egr bolt where it pipes from the head next to the intake manifold.
