Hey guys, 1996 Q45 base. I need to call upon your assistance once more. It seems that my bucking/stalling/dying problems are the result of a cam position sensor error. Well, that is the OBDII code (3040 as I recall) says. I had the sensor replaced and am still throwing the code and experiencing the symptoms. So, I want to replace the connecting wiring between the sensor and where it first links into the feeds back to the ECM. My problem is that I cannot find the part.
I tried calling the parts dept at Infiniti Scottsdale (who I gather has a very helpful parts dept), but they transferred me to the national parts dept and I was informed that the part was discontinued. My google searches had turned up lots of cam position sensors, but not the wiring. Anyone got any insight on this? Is there a Nissan part that would use the same four prong connector style for that short run? Am I stuck re-fabricating it myself (or hiring someone to build one for me)? If anyone is parting out their Q (94-96) I will pay top $ for this little run of wire and connectors. Let me know.

Normally the connector there doesn't fail, just needs cleaned and whatnot. I'd try that before splicing a new connector in.

Yeah I have tried that approach, and even had the mechanics fiddle with it for me, but the problem persists, intermittently. Which to me, seems like an intermittent open in the line (I had a similar intermittent function problem with the left head lamp, from wiring). I love my Q. I've had it for years and want to keep it, but when it dies multiple times on a short drive at stop signs, when starting, while going down the road, and then the random bucking routine in motion, it really hurts. A simple sensor signal error appears to be the cause, and it wasn't the sensor. So any ideas or insights on getting this piece (I really don't want to go the self fabrication route, though it is looking more and more likely) would be highly appreciated.

I still think the connector is an unlikely source for your problem - but I can't say that for sure.

Is this the one you need?

Note that there's some insulation missing on one of the wires, so it may not be in any better condition than the one that's on your car.

Either way, if you want it it's yours for the low, low price of free. :D I yanked it off of a 94 with about 200K on the clock at the pull-a-part after reading your thread. It was close to the throttle body I was pulling, and they didn't charge me for it. Send me a PM with your mailing address and I'll send it out to you in the next day or two.

As a kind of sad side note, the Q selection has really dropped off this year, at least at my pull-a-part. I'm not sure if we've worked our way through the majority of the first generations now or not - but I fear my days of always having a parts car 15 miles away are over.

Heath - - Same here.. I could usually find at least one G50 around here.. Y33 are starting to appear more nowadays. It looks like Atlanta still has a few G50s between p-a-p locations.

Well I cannot see the images, but hey let's give it a whirl, my mechanics say they can put it in if I can get the part. I will figure out how to PM you and send you a check, or financial instrument of your preference, for shipping if you want to send it my way. I don't know if they changed the wiring cluster between the first and second gens (almost ten years of Q ownership, I should know).
It is throwing that old chestnut p0100 MAF code, though not the cam one, after doing a contact cleaning routine. The symptoms are largely unchanged, though they seem to go away after warmup (though that takes a while and it barely functions before that point). I have already replaced the MAF once before recently. Any thoughts/insights on the best approach to fixing this?

Switch to compatibility view if you're using IE to help with the pictures loading. Or Firefox and Chrome don't seem to have issues with it...

Was your MAF New OEM, aftermarket, or used? Did the symptoms change any at all after replacing it? I've seen a lot of extra grounds for the MAF plug... it's an issue people have chased before. I got your address in the PM. It'll go out in the next day or two.

The pics loaded eventually. My anti virus (avast) and chrome don't always play nice together. After I changed the MAF (it was used) the symptoms abated briefly, but they always seem to return (chugging, wildly fluctuating RPM at constant throttle ect.). They have shifted to being a low speed/ low rpm issue (near idle through 1.5k), whereas before it was more of an issue at >40 mph (2-3k ish rpm). Now, before warm up, the car just won't break through to a speed over ~25 mph, but then the issue will clear momentarily and it will drive perfectly fine. Really awful tracking this one down.

My mechanic mentioned that my cracked air intake boot might also be the source of problems. It was "professionally" repaired with duct tape, but likely has developed air leaks, and is again a part that I can't seem to find. Could this be a main fault trigger or is it more likely a contributing factor?
