Intake manifold
I’m getting the code p2015 intake manifold runner position sensor. I replaced the whole intake manifold and I’m still getting the code, could a bad throttle body be the culprit of this? I have a 2012 A4 quattro |
Did you clear DTCs afterwards? Replacing the whole manifold should have replaced all possibly involved components.
The service manual referred to an adaptation for the intake manifold runner, but I could never find such a test in VCDS. There was a throttle body adaptation which I did run since I had removed the throttle body to clean it (and technically you removed it to replace the manifold, so might be good to run it anyway), but that device is not related to the manifold "runner". |

The specifics are muddy, but I found the throttle body test under basic settings after replacing my manifold, so I did it anyway:
Throttle Body Alignment (TBA) - Ross-Tech Wiki For us, it'll be the UDS instructions. Power on, engine off (same as for normal VCDS DTC scan; cycle power on the car if you had cleared codes), run the test. See if it helps any. |

Well, I think that's somewhat normal. Why we get carbon buildup, from the PCV throwing oily air back in to be reburned. But too much might mean something else in the recirculation process is not working correctly. But I still don't know how that would tie back to a P2015.
If you feel along the backside of the manifold, you'll notice an arm that moves. If you push on it hard enough, you'll move it. That's the arm that moves the runner inside the manifold. This is what your code is talking about. The sensor that detects the position of that runner rotation is not sending back an expected signal. There's some pictures relating this in the testing the manifold section in the fuel injection and ignition service document. In that document is also this: If the fuel rail is removed or replaced, the intake manifold runner position sensor -G336- must be adapted to the Engine Control Module (ECM) -J623- . Use a vehicle diagnosis tester. But I could never find any test to do for the runner, like I found for the throttle body. But I had no follow up issue, so it wasn't a problem. |

Pay for a day and grab the PDFs relevant to your car so you don't have to pay every time you want to look something up. |
Solved the problem for the p2015 code it was a defective heater valve which is behind the engine, it shares vacuum with intake changeover valve https://cimg9.ibsrv.net/gimg/www.aud...18a7119ed3.png |
Hi Did this heater valve replacement clear the hesitation you mentioned ?
