Camshaft advance angle on B1 stuck on -128

Tosh · 10-03-2022, 04:30 PM

Hello All, this is my first thread here, so first I want to congratulate everyone for making this board as awesome as it is.

For a few months now I have a cool orange (pics soon) 2011 370z. I have around 3000 miles on it and I'm getting comfortable with the specifics of the car. I got a Kiwi 3 OBD scanner which I'm using with Torque Pro and a plugin for Nissan to get some specific engine parameters.

I'm worried about the camshaft advance angles on B1 and B2. B2 is reported, changing and overall looks right. B1 is stuck to -128 all the time. Checked the car on a professional diagnostic equipment (not Nissan official) and it didn't read any value for B1.
Swapping the sensors did not change anything, so they should be fine.
It's worth mentioning that around 1000 miles after resetting LTFTs, the B2 side got around 3, B1 side stays on 0.

While driving the car feels good (as far as I can tell), except when the weather is very hot. When outside temp goes over 85F during city driving, it slightly loses power on low RPM and has jerky acceleration. This could be because of the KN short ram intakes, the previous owner fitted (and I plan to get rid of).

Is it normal not have that reading on one side only?
Thanks!

Yes it seems to be normal... My G37 shows the same and I suspect this is a bug in the ECU and it just returns -128.
