I just recently bought a used 2003 manual 350z. Went acculturating quickly onto the interstate I hit my preset rev limit of 6600. I set this limit just to be safe because the car is older with a lot of miles/hours on the engine. After hitting the rev limit these three lights came on. I check the engine code, it was for my cam shaft position sensor bank A. I just recently replaced this exact sensor not even a week ago for the same reason, under the same circumstances. Is this a well known issue? Does hitting a rev limit trigger this code? The car is running fine, no notice issues. I cleared the code and the light did not reaper.

Just curious if this is coming to be worried about, or just a quirk of the Z. Thanks for any feedback.

 

I bang off the rev limiter every shift because I never let off the gas.
replace sensor with an OEM

 

I just replaced that exact sensor with an OEM not even a week ago. The sensor should be completely fine. I’m thinking that whenever I hit my rev limit there’s a conflict with the engine software that makes the car think I had an abnormal engine event

 

Did you set the warning light at 6600? If that is what you did, it's just a warning and doesn't cut off anything

 

I set what I assumed was the rev limit on the multi gauge on the dashboard. It definitely limits my revs. I previously set it for 5k rpm and it stopped me there

 

The "rev limit" as you're calling it is just a setting for the shift light on the dash.

If you previously set it for 5K rpms, then the light starts blinking at 4500 rpms and it's then solid at 5K. It does not cut the engine at 5K.

 

If the fault code is camshaft sensor a, then that needs to be replaced. If you did not install a quality sensor, then the new one just might not be getting the job done. I replaced both of them on my DE and it cleared same problem. I had both sensors triggered. I was surprised at how great the car ran after that. it had been pulling timing ever since I have owned it and I didn't even know that.
