Check out that angle for bank 1 intake. Here's where it was before you replaced the ECU. Remember how it never changed?

Is it safe to say that theres really no harm in deleting the code from the ecu once you've verified there are no mechanical issues, then? Of course, barring that the ocv or sprocket break later down the road? |

No harm. Do you have techstream to check those learning values?

Also, I've read pretty much all the threads I can find about this kind of error code, and I've swapped OCVs, checked sensor clearance, and pulled the timing cover to check for the loose spring in the back or to see if the cam vvt lock pin was broken (i.e. loose cam). Best I can tell is that the previous owner had this problem and fixed it with the OCV, as one is obviously new compared to the other 3. Also, the vehicle runs fine until limp mode. Also, will deleting the code prevent it from entering limp mode due to this issue? |

Clearing the code will clear limp mode but if the underlying cause still exists, it will throw it again. I don't know how long that takes.

I think by “deleting” code he was referring to disabling the code in the rom similar to how you would disable the cat efficiently CEL on a catless header. His point being that it drives fine until it gets mad and throws the code and limps. That is my interpretation of his post anyways. |

Yes you can disable the code, will stop it going jnto limp mode, but obviously the underlying issue is still there and may eventualky cause other issues.
If you have done the mechanical checks and swaps. Id probavly swap in a replacent ecu as its fairly easy and cheap like $100 on ebay |

Since that is the case, I don't see how buying a used ECU will solve my problem in a reliable way as those burnt in values will (likely) be different than what they need to be on the used ECU, no? Additionally, the shop I'm working with is" extremely busy," buying my own tactrix cable also means buying a laptop, and I have never done a reflash. I'm technically inclined, but the risk remains, and I feel having the shop delete the code is likely better in my case |

I dont think theor are burnt in values in ecu, i think the problem ecu,s have actual hardware issues with the interfaces that control the valve actuatoror the inputs from sensors If done a or been involved in quite a number of ecu swaps no issues. |

I've heard it now from the local tuner who has seen issue before. The learned values for cam position dont change after a flash. I suppose it is possible that theres a witing issue/ecu plug issue, but that wouldnt necessarily explain p0016 as p0016 is a lack of proper timing, not a lack of signal. That's why the sensor clearance TSB really has nothing to do with this family of codes.

See, thats where you are wrong. I had this code, the shop that works on my car was able to diagnose and correct the issue. The sensor was sending 0 as values (same as the screenshot you have), he swapped the sensor for a new one, but that still didnt fix it, he had to "reset" some values in the ECU (maybe he was refering to these learned values people speak of) and then everything worked normally. I feel like I cheated on this one, for as much trouble as people seem to be having with this particular issue, it took the shop just 1-2 hours with 1 person on the car to fix it. The car was tuned with Ecutek and the shop is a master tuner for ecutek, if that means anything (he had to change the hardware he was using to reset the values, as the laptop he was using initially wouldnt allow him to do that).
