Hello! I have just mount a brand new complete intake, but I still got the p2015 code.

I have tried to make base setting with vcds but it doesn’t help. It’s a tdi 170hp engine code cega. Is there any who have any suggestion what to do? Regards Markus

Well, literally 15s in Google returned

The P2015 code means that there is out of range performance from the bank 1 intake manifold runner position sensor. When this occurs, the ECU detects the out of range performance as it is looking for a specific values and when they are not seen the DTC P2015 is set.

This is an issue with a sensor, not a casting.

I guess that the sensor is mount in v157 electric motor, and that one is brand new! I don’t know what next step to do is?

Did the wiring look OK as you plugged it into the new v157/G336?

 

You could check for 5V on pin 1 (yellow/grey) relative to pin 3 (brown/green) with at least ignition on.

 

If that's OK, test continuity of the three wires to the engine ECU, #2 on 5-way to 27 at ECU (purple/black wire);  #4 on 5-way to 35 at ECU (brown/green); #5 to 50 (red/green).

Thanks for the information! I’ll try to measure and see what I can find!

Hey! I found something that I don’t think it’s right. Between pin 2 and ground I have 1,3v with ignition on, my computer says it should be 0,5-0,8v

can it be faulty ECU?

That's the position feedback signal from the flap, so more likely an issue at that end, or setting-up problem. ECUs tend to be extremely reliable.

What 'computer' is telling you about this voltage range, do you mean VCDS?

Try adaptation or basic setting of the flap; whichever is recommended when replacing.

I use Bosch and vcds. The bosch computer tells me 0,5-0,8v with ignition on.

my brand new intake have 1,316v that’s really strange. I have modified my old intake so it’s 0,7v with ignition on. The voltage when v157 is activate seem to be ok 3,9v.

I just notice that when you start the engine pin 2 have 3,9v but after a few seconds it’s like it’s losses it’s signal and getting back to 0,5-0,8v or 1,316 depending on which intake I have connected. I’m just about to check every cables.

Wino, do you know what right voltage is V157?

ignition and idle? I can’t understand why it keep putting out p2015??

I know nothing about what voltages to expect, except that the position feedback potentiometer has 5V (pin 1) and earth (pin 3) connections, so its output on pin 2 can be expected to vary somewhere within those extremes, as the flap moves. 

The end positions (maximum open and minimum open) are generally what are memorised by the engine ECU during adaptation of a new valve.

I have measured pin 1 and 3 and I got 5v. 
output on pin 2 is in right range for what the Bosch computer tells me, so I don’t know what to do the when it have the expected voltage.

I maybe code it off with some help, but I really want to solved it the right way first.

@Sevcon hi ! it's been a few years i can see but have you managed to resolve the problem?

 

@Breezy_Pete i have looked at the wiring diagram and run a few tests as i have put new intake on, swapped between 3 sensors and i still can't run adapation. 

 

i tapped in the wiring by the 6pin black connector under the manifold to do some readings with a multimeter. i can see the 5v from ecu, the ground is ok and checked the other pin too and i get a return voltage modified when i actuate the flaps manually.

ll these considered and i still no luck.

 

i also went further and supplied the new sensor with 5v and ground with it being out in my hand and spinned the center manually simlutaing what the opening of the flaps would do and did some readings. with it being in my hand the voltage goes from 0.5v to about 4.37v.

when i connect it to the manifold and all back into place i only see 2.75 v roughly and on actuating the flaps manually it drops to 1.24.

i don't know/understand what values would the ecu need to see in order to successfully run adaptation.

 

excuse the fact i was talking in Romanian over the video and please have a look at the photos. 

 

honestly been over a month i am trying to get this fixed and it's driving me crazy

 

 

there is a limit on videos so i will try here, hopefully the video is clear enough

sorry for double posting  this edited video should be clearer

The new intake manifold was the issue...

The flaps would start moving but not the sensore until after half way...so would get a small voltage out and ecu would think the flaps are at 50%
