So i was doing some spirited driving list night.. (in actual fact i was seeing what sort of 0-100 times i can do. (Entering the freeway at the on lights officer) ;)

First run was all good. Second i got to the top near the top of 3rd and felt like a fuel or boost cut.. CEL came on.. limp mode engaged.. Just checked the numbers (and cleared them).

Came up with:

P0018 OBD Trouble Code

1 result found

P0018 - Generic Type Powertrain - Fuel and Air Metering - ISO/SAE Controlled Description

Crankshaft Position - Camshaft Position Correlation

Location Bank 2 Sensor A

Anyone got any experience with this.. I havent tried driving it since i have cleared the code.. I am hoping it will just go away. I am thinking i should drop the boost down a bit too.. currently running LPG, with dump and midpipe replaced, break wire cut, bleed valve with factory controller removed running approx 16psi.. (factory guage reading).

I really hope i aint broken it.. :(

You should have dropped in mate, the generic code descriptions are crap. The consult 3 would have explained it better and allowed direct testing of the sensor. At least the limp mode went away and it wasn't the AFM...

If it's the cam sensor I may have one, but try it out, it can only throw another code and go into limp again...

Bugger. Even after clearing the code next start the cel returned. Attempted to drive it to pickup my kid from his grandma's it still was in limp mode though appeared to be driving ok. Filed it up with gas. Then picked up the kid and then it wouldn't start. Kicks over gets ignition tries to get the revs up to idle about a second and a half then stalls.

f**k.

Had to get the kid home so will have to go have a look tomorrow or Saturday.

Will double check the cel and the hoses and connections though it sounding expensive.

Strange that I managed to start it about 6 times and drove it for 40ks before it died. Only difference I can think of is that it's parked on a angle now. Maybe I'll Jack it up and start it. Really painful cause I didn't get it home.it's on the side of the road.

Suggestions most welcome as always.

Timing belt out? Had a few with that code

"its easy on my C34..."

No timing belt.

Sounds like it might be crank and/or cam angle sensors. Wouldn't be too fussed about the air fuel code considering your running gas

You need the consult 3 unit, and I have the software on my laptop. Would you like me to drop around one night? I can bring the cam sensors, I definitely have one, just not sure on the drivers bank sensor.

    • Hey crew, Failed my WOF cause of a lower control arm, and I've decided to hit both arms, and also the compression rods at the same time(seems they're gonna be the most likely upcoming failure points from some discussions with the lads over on the G35 reddit). I've looking at these form Z1:  https://www.z1motorsports.com/front-suspension/hayaku-automotive/hayaku-g35-front-compression-rod-p-40716.html https://www.z1motorsports.com/front-suspension/hayaku-automotive/hayaku-g35-front-lower-control-arm-p-40674.html I asked Z1 if they'd work as it's the same platform, just RHD vs LHD. I basically got told "Lol dunno". Specifically they aren't aware of any difference but can't guarantee fitment as they haven't done it on a 350GT. So guess I'm asking is if there is any issues with using 2005 G35 coupe suspension parts on a 2005 350GT coupe? Orginally I thought it could be something in the way of the arms that each control arm is designed to be positioned around, but that'd be an engineering nightmare for Nissan needing two different shaped control arms 😅
    • ^ This. The mode door actuator is a common failure, as is the actuator and/or the actual valve for the coolant flow control valve. I also don't know how available the mode door actuator is these days. I've been meaning to look into it and get one from wherever is possible, to keep in the shed for the rainy day when mine eventually fails. Anyway, the advice to you is to search the usual NOS part supply places, or even just go to Nissan and see what they list.
    • Have you got a pic of the actuator? My guess is that unit has failed internally and was flopping around, so the previous engineer who owned it forced it to be fully open to cold air (blocking the heater core path). As far as you can tell, is anything else wrong in the system? Likely you just need a new actuator (not sure how available they are) and then "installation is the reverse of disassembly"
    • I'm happy with the Lsailt unit that I put in, it puts full Android on the top screen so you can run whatever Nav and other Apps you want, while still existing inside the factory functionality like automatic reverse cams, audio input switching, retains factory bluetooth etc. Not cheap and the install was moderate (not simple, not hard) Yours is a V36 not V37 though right?
    • Yeap, all the NC's that I originally looked at that had a hard top were PRHT, which makes the roof line look horrible, hence why I said nope to them My only caveat for another MX5 was it needed to have a hard top, and initially I didn't think you could get a detachable hard top for the NC,  like my NB had Again, a big thanks to Matty for helping me source the detachable hard top for my little girl, they are as rare as hens teeth in Australia, and the few people who have them, keep them Also to Greg, for initially pointing me in the NC direction NC PRHT 🤢🤮 Not mine (I really should take more photos of my car), but a NC with the detachable hard top 😁 To me, the difference in how the detachable hard top roof line looks, and how it actually follows the bodies lines, like they do on NA's and NB's, is chalk and cheese compared to the bulbous looking PRHT
