I was changing the fuel filter today and I broke a little yellow 1 wire switch/sender that screws into the side of the block next to the oil filter. Check engine light came on after about a minute of driving after the broken switch. I thought it was the oil pressure sender but my oil pressure registers normal. This is on an 85 5speed 4runner 22re.

Hmm maybe a knock sensor connector

SoCal4Running

Yup that would be the knock sensor, probably a little down on power too.

Poopy

O great, how much do these normally run? I know on my mitsu they are like 130ish.

GTE4runner

I dunno but I think I have a good used one on my scrapped 86 22re. If you're interested let me know.

SoCal4Running

From Napa they are around $150. Did you actually break the sender in half or just the plastic makes up the plug? If its acually broken I would try a junk yard or wherever before going to the stealership.

Poopy

I broke the little plastic piece that sticks out so you can plug the wire in. How much do you want for your used one? I'm cheap. I really don't want to spend that much money on a new one.

BTW, your right. It has no power and surges. The check engine light comes on about a minute after driving and until then it is fine. Then the light pops on and starts running like poo.

You definitly broke the knock sensor, I know this because we just broke mine while trying to pull the head and not seeing that wire attached to it. I got mine for dealer cost (dicount from friend that works there) $110 new.

PM or email a memeber of this board "Toyota Parts Dude" he has alot of parts and definitely has one for a 85 22re because I asked him for one and that is one he said he had, and it was inexpensive(I'll let him tell you how much, but it was cheap).

$30 shipped for the knock sensor.

I'll take it. Sent you a PM and it said something about a receipt so I don't know if you got it or not.

GTE4runner

Yeah the message you saw was asking you if you want to be notified that I received the message, I got it.

I sent your sensor out 20 minutes ago

I'll go get a money order and send it off to ya today. If you checked your PM's, went to a junkyard and pulled one off an old Celica for temp use. Just spliced the wires and it works.
