Need Advice! New Clutch Kit, P0335 Crank Sensor Code.
 

Hello, this is my first time posting, so I apologise if I'm posting in the wrong section.

I have a 2011 370z 6MT, in Australia they only came with the NAV & sports package.

I recently had a 6 puck clutch and light weight flywheel kit from Z1motorsports, and also a Zspeed CMAK installed. After the installation the car drove fine for 15 minutes before it went into limp mode and refused to rev above 3500rpm, which then gave a P0335 code for the Crankshaft Position Sensor "A" Circuit.

So we went ahead & changed the sensor to a new OEM sensor from Nissan, but the problem was still not fixed, we also had someone to come and inspect the wires to make sure there was no short in the circuit but that was also fine. My mechanic says he's 100% positive that he installed the kit correctly. Everything else works fine, clutch engages and disengages fine, so I'm not sure what else I can do and I really don't want to put the OEM flywheel back in.

I've added some photos for you to look at in case it helps, thanks in advanced.

Check for pinched wiring between the bell housing and the back of the block. It's been know to happen on clutch installs.

If you haven't done so already, check the FSM (link in my sig) for adjustment procedures (if applicable), troubleshooting steps, wiring diagrams, etc.

Alright thank you, I’ll pass the information on to my mechanic. The Australian flywheels can’t be different to the rest, could it ? Also anyone used Z1 flywheels and had problems ?

I removed the Z1 flywheel and installed the stock dual mass flywheel, because Z1 hasn’t been replying to any emails and I needed the car on the road.

So after driving 100km (60miles) and keeping the engine revs below 3k rpm, the factory dual mass decided to break/damage, according to my mechanic he said that the 6 puck clutch had too much force for the factory flywheel and damaged it along with my starter motor

:eek: :icon14: :confused:

Well that escalated quickly :confused:!!!

If after replacing the stocker the revs were fine I would guess the CPS ring on the new flywheel might be suspect, did you compare the teeth position and condition with the stoker? If the CPS teeth on the new flywheel are bent or missing, it will throw the CPS off.

It sounds like the dual mass springs have failed, do you have pics?

I didn’t really have a chance to compare them, but once they’re both out of the car I’ll put them side by side cause now I’m getting a new clutch and flywheel kit locally, my mechanic is saying exactly what you said, the teeth for the CPS have some differences.

I don’t have photos but I’ll be sure to take some when I get the car back and the flywheels.

Appreciate the replies

What else happened? Did you resolve?

Maybe this is why Joe says to not use Z1 clutch kits with the CMAK :confused:

He told me it was a clearance issue with the shift fork but maybe there is more too it.

OP, Call Joe@ZSpeed :tiphat:

Doesn't have anything to do with using the CMAK with that clutch. It would not effect the timing ring.

If you did not have p0335 before or any running conditions another possibility is th at it isn’t a problem with the sensor signals but a problem with cam and crank correlation. As in your car is no long in time. Some people don’t realize that the flywheels need to be timed. There are pictures on jwt support page that show pictures of this. If this is the issue unplugging the crank sensor should cause the ecm to use both crank sensors to use each other to see if the cams are “close enough” in time. The fuel which is usually controlled by the crank sensor is then ran on a base map.

Guys.

Very similar issue, Z1 clutch w/ six pucks, Z1 CSC elimination kit. I have driven the car without issue for about 2 months. It failed the sensor on track at ECR this past weekend. Took the car to my local Nissan Stealership. They confirmed sensor failure. Car sensor ordered for replacement today. I'll update when I get the car back. Hopefully fixed, but I'll let you all know.

Got the Z back this afternoon, CKP sensor replacement did not fix the issue. I noticed that there are metal shavings all over the tip of the sensor. It's like something inside the bell housing is abraiding or wearing away. I'll be taking the car back to JoTech in Dallas for further investigation. They did a new clutch and Z1 CSC elimination kit install for me in Late June. I'll update with what they find after the appointment.

I thought I had mentioned the dowel pin in crank to be mated to Flywheel. I guess I had not. I'm sure it's impossible to do that, but never say never.

Well I have news. JoTech dug into this issue for my problem and discovered that a tooth is missing off the reluctor wheel attached to the backside of the new Z1 Lightweight Flywheel. They are going to evaluate the possiblity of welding it back on against the reliability of the welded tooth. I asked them if a new flywheel is needed, and they have not gotten back to me on that question. I'm sure Z1 will want to know that one of their flywheels had a failure of this type. Maybe they'll even cover the failure with a new one. Fingers crossed on that one.

I'll update this thread again when I know more.

My opinion at this point is check your car's flywheel for damage if you have this P0335 issue. In my case I have a new flywheel, so the shop looked there first.

My 370Z Flywheel damage - only 3 months old. Forced P0335 code
 

I got the car back from JoTech yesterday. It's all better now. A new Mid-Weight flywheel from Z1 fixed this issue for me. Many thanks to JoTech and Kevin, Tony, Seth and Christian for their hard work and diligence. The flywheel and missing tooth are out and the new Mid-Weight Z1 Flywheel is in. What a difference this 21 pound flywheel makes. It is smooth and quiet. It revs better in my opinion than the lightweight unit. My guess is that the 370Z engine likes a bit of weight on the crank in order to rev smoothly and stay relatively quiet. The P0335 code is gone now. This broken tooth was the direct cause of the poor running and failure to rev smoothly.

I hope none of you run into this issue with your 370Z, but perhaps my experience and photo essay can help you identify and/or clarify this issue for your P0335 code

Here are photo's of the damaged flywheel and the missing tooth:

Sorry for everyone who messaged that I haven’t responded, I’ve never used a forum and didn’t know how to find my post also my email wasn’t and still isn’t receiving any notifications regarding this post, sorry again.

But yes I’ve resolved the problem and it turned out to be the exact same problem which Corsair had, one of the teeth on the back of the flywheel was snapped off, I’m unsure if it’s a problem which was caused by the mechanic or the product was defective but it also happened to my factory flywheel so I’m guessing it’s due the installation because I’ve had a new flywheel installed from a different shop and it’s been running perfectly fine since then
