Cas (Cam Angle Sensor) Help!

Hi everyone, first time posting on this forum so take it easy.

Without thinking i've removed the cam angle sensor of my neo without making any marks. And making it worse i've turned the engine over a few times with the sensor off.

I was just wondering how serious this situation is? the pin/input shaft that going into the end of the cam shaft looks like it can only go in two ways. So is it a 50/50 change that it will go in the position that it was previously in before i took it out? or will it be 180 degrees out of its original position and will send the wrong signal to the ecu.

how noticeable will the effects be if it were to be in the wrong position. will the fix be as easy as rotation the pin/shaft 180 degrees?

Any help appreciated

Thanks. :yes::cheers:

I think you need to get the timing marks lined up so its on TDC, then slide the Cas in so the half moons join, then hopefully theres a mark where it was sitting or else its about half way and need checked with a timing light

oky thanks for the reply man!

This mark you mentioned where are they located? Im unsure of what position the timing marks were when i removes the cad, so i was wondering if i did put it back at TDC theres a chance it still maybe in the wrong position.

It only goes in one way, the slot is offset, line up the bolts withthe old marks, and check with a timing light

Exactly this. Doesnt matter where the cam is, as long as you have the half moon (these sometimes break but sounds like yours is there) you can slide the CAS over that, rotate it to line up with the bolt holes, do the bolts up loosely and then get a timing light and set the timing

Neo doesn't use the spline and half moon system but can still only go on one way.

Whether you have marked it or not, you still have to set timing with a light.

The marks are never going to be good enough.

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
