I've searched around here and have seen a lot of info on the sensors in the back of the 3VZE (CSI time switch, coolant temp, etc..), but I can't seem to find a picture/layout that looks exactly like mine.

My '91 Runner had different sensors back there, there were more of them. This '92 Pickup I have now only has 3 back there, one on the left, then a big coolant hose, then one just to the right of the hose, which is a small sensor with a wire just clipped on top, then one on the right. I am ohming them out to check them for a warm start issue, and just want to know for sure which one is which.

If someone with knowledge of them can take a look at these pics and let me know for sure which is which, I'd appreciate it. Sorry about the 2nd pic, crappy camera.

By searching other posts and seeing FSM's, I am thinking, from left to right in these pics, they are as follows:

LEFT - CSI time switch

MIDDLE - Coolant temp switch

RIGHT - Coolant temp sensor

I could be wrong, which is why I am asking the pro's here.


Thanks.

 

I'm no pro, but this link has some good diagrams and pics... hope it helps.
