I am currently having two codes coming up after a while of driving being:

Code 14: Vehicle Speed Sensor
Code 34: Knock Sensor
The knock sensor error is thrown straight after the vehicle speed sensor error is thrown.
Does anyone have any ideas as to what could be causing this?

OK. So a bit of an update: I fixed the knock sensor, it turned out to be a broken wire. The speed sensor is still an issue. The engine light comes on and then the TCS and Slip light comes on. If you turn the car off the TCS and Slip light go out when you turn it back on. When I clear it it goes away for a while, then randomly it comes back. Doesnt matter on the type of driving. Also when I plug in my laptop, the speed gauge in Nistune has no reading. The only thing I can find with the same problem is this but it talks about a de-limiter and I am not aware of my car having one. Any help would be appreciated.

I have traced the problem down to the dash. The speed signal goes in from the speed sensor but doesn't send a signal back to the ecu? Any ideas why? Does anyone have a circuit diagram? Or can provide any info?

Oh, well in that case the dash has a fault. There's integrated circuitry in there to do the speed signal translation (takes in a saw tooth AC voltage from the speed sensor and outputs a 0-5v square wave for the ECU). That stuff would be nigh impossible to repair unless it was a broken track on the dash circuitboard or something equally trivial.

      Are these the Dmax ones you are in reference too? https://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35#description Not a bad idea to get the uni flange ones. I have sent just jap an email too. Will see what they say lmao. Only thing is the Dmax ones are on a big back order. Low key anything will be better then my OEM ones I got as they are sounding like popcorn when I go under load lmao 😂☠️🪦.

      Compatible rear drive shafts R34 N/A?

      By GTSBoy · Posted

      They should do. I have S14 (or something S chassis, anyway) driveshafts in my R32 (because my diff flanges have 3x2). They're the right length. When you go looking for R32/3/4 driveshafts (for turbos), they're all the same thing, so are the same length. So there really shouldn't be any reason why those cheapies from JJ won't also fit an R34. R32/3 NA should also be the same thing. The (3x the price) D-Max ones are uni-fit. They have 5x1 and 3x2 bolt holes and say they cover all the cars. So that would also suggest that they are all the same except for the flanges. And in that case, the flange goes both ways. I'd be buying the D-Max ones if I ever have to replace a shaft. Because that will open up diff options without needing to juggle shafts also. Juggling shafts is gay.

      GReddy Injector Help!

      Yeah with the adaptors they do look like the photo above - just the fitment within the plenum itself and then further with the rail to the intake is questionable - we shall see tomorrow hopefully once I get some replies from Aeroflow, maybe those bosses are the missing piece....

      Should be fine, if you have it sitting too far in, you end up just spraying the walls and have shit idle. You "can" run them like that, however I don't think it's a great idea (also depends on your plenum, might be good to just get the injector bosses first, mock it up and see if you need to get the bottom extension) Ideally your injectors, with the extension should look like this  (Not my photos, just Google)

      Thanks for the replies guys, it's really appreciated.  It seems the kit was supposed to come with those injector bosses but hasn't. Unsure if they'll help as even with the adaptors to make them a 3/4 height injector they still sit too far out so mount the fuel rail?
