I am not a car nut. I live in an apartment complex (= no garage to experiment) and never taken an auto mechanics class because it was phased out during my freshmen year in HS.

newbie need your help .

I've found a loose part, as in not connected to anything, in my battery compartment.

It it a little over 2.5 inches long. One end is about .5 inch green plastic cog with its teeth at an angle (45 deg) in respect to beginning perpendicular to its perimeter. when the cog turns, it opposite side inner circle, a shaft, turns. It has an O-ring closer to the opposite end. in outer circle of the opposite end has screw threads .5 inch in length. This screws into something. At the base of this screw, it is a metal round base, but it has an appendix that is also round and has a hole in it. I guess you can bolt it into something using this hole.









I'm not sure what this is since our books are crap. They're like a time table chart, it tells you that 9x6=54 but it doesn't explain the mechanic of the x.
I will try to upload a pic to a hosting site as soon as I can, Or I can email someone a pic if it.

It might explain why my oil is eaten up.

Thank you.

 

Sounds like a speed sensor kinda....but get a pic.

there's a sensor (speed sensor?) that's attached to the side of the tranny. is there a wire(s) attached to it?

 

funny thing is he hasn't mentioned anything about a weird speed reading though.

 

No wires, just pure mechanical piece

 

its probably your idle air control screw.

 

Bump, pics added in 1 post

 

I say some one left a extra sensor in their. Looks like a speed sensor to me!

 

Really, When I bought the car. A mechanic said I was missing some sensors. This is a Speed sensor? Even though my speedometer & odometer moves. Interesting. Do anyone mind pointing out pics to where it goes?

 

I dont have a pic but look down on the back top of tranny

 

that is 90% a speed sensor. I am not positive, though. Look under your oil filter, there should be a similar thing there under it connected to the tranny....how it ended up by your battery the world will never know.

The only thing confusing about it is the threaded part on top. I don't remember that being there. Also, a speed sensor has wires and a connnector coming out of it. You'd know if it was missing..... I have a feeling that nissan uses those green or yellow spline gears for many of their sensors. Even the shape is similar to the speed sensor though.....those threads keep throwing me off though. Also, it seems too short to be a speed sensor.

Maybe a speed sensor for an entirely different car? It's definetally a nissan product...

 

maybe that's the hookup for a speedo cable on a 2nd gen? sounds dumb but who knows? but then again isn't there some other sensor on an a/t, called a revoultion sensor? i don't think that's the bottom half of a distributor because i think that's metal gears right?

darkwing are you a/t or m/t?

 

speed sensor...pretty sure....but it's connected by a speedo cable. 3rd gens don't run these. we're rocking electronic speed sensors.

 

The only green plastic I've seen on these cars is the access cap for the cold AC line. It would be funny if it wasnt even from your car or any Nissan.

It does resemble the speedo pinion on a diagram, but doesnt seem long enough, and is a few parts away from being complete.

 

Automatic Transmission.

The last group who checked my car was First Nissan of Simi Valley.
I'm surprised that these fools with their 21 pt inspection didn't ask me about this part or forgot to put this in my car. My oil consumption is high though. I getting worried

 

That thing is not from a 3rd gen maxima...

 

sad to say that is exactly what it is ive taken my engine and tranny out enough to know it hooks up to the speedometer via cable but if you guys are running electronic then there is no use for it unless someone swapped out your engine and tranny for a second gen one, i would take opics of your engine bay by the firewall and on the tranny to see where it could be missing

 

I would have to say the speedo cable hook up from a 2nd gen. I would check the one in your car if its been changed the tab that holds it in could be broke (was in my 87) if the person who did wasn't carefull or used it as a pry spot. if you look down from the fuel filter you should see 2 wires come up from the tranny.

and that brings up a ???????? would a 2nd gen. tranny fit in a 3rd gen or 3rd into a 2nd???

EDIT: a vg30e 3rd gen.

 

well either way the 3rd gen would need the electronic VSS so... maybe the installer ripped out the 2nd gen cable VSS and plopped in the electronic version. Because even a 2nd gen transmission wouldn't mean you would read speed via cable... unless you had a 2nd gen cluster as well.

 

Speedometer pickup, not from your rig though.

 

100% sure it is a speed sensor located next to oil filter, two plugs sit above oil filter, 1 for speedometer sensor, 2 for oil level sender. if you don't have one in your car then you have no speedo or cruise control. just replaced my brother in laws 3 weeks ago. takes 10 mm screw and just pull out, push in and do up screw and plug in.

edit:
unfortunately after looking at pics closely it apparently takes a cable so wrong model car, maybe 2nd gen, my old pintara used to take a speedo cable instead of electrical voltage. bit of a bugger when the end snaps in the speedo, why they made the thing out of plastic i woul not know.

 

Thanks you guys, I will take pics of my engine bay this weekend.
