Hello, I just bought a 04 350z touring roadster, I bought it knowing the check engine light is on, I took it to autozone to have them run my codes, it came back with 6 codes, 3 of which are duplicated. The codes are p0011, P0021, and p0113. The day I bought it I changed the oil and oil filter. I have a g35 coupe as well, so i tried putting my Gs cam shaft sensor in the Z, didnt change anything, I tried cleaning the mass airflow sensor, the check engine light keeps going off. Any body run into these codes before and fix it?

 

The P0011 and P0021 indicate an error with the intake valve control, while the P0113 is for the intake air temperature sensor. I find it odd that you have both sides lit with the IVT DTC, I suggest you check the connections on those. The air intake sensor is built into the MAF sensor assembly, inspect the harness cable for this too as well. Refer to the service manual for further information on diagnosing the cause of these DTCs. Let me know what you find out.

 

Well Im glad to say the problem was resolved, turns out it was a misaligned clutch and flywheel, but the tech said the flywheel was done and the clutch was fried, ended up going with a Luk clutch and Jim wolf single mass flywheel. Check engine is gone. The tech did say that the alignment was 180 degrees off as well. I learnt how to drive stick on a dead clutch and flywheel lol, once I picked up my car I felt like I was driving a whole different car. So for anyone with p0011 and p0021 codes right after a clutch job the problem is most likely the tech who did the job sucked at his job. Cheers
