Witam,
Napotkałem się z problemem w mojej Isi 2.0 cdti 2011. Przeszukałem forum w poszukiwaniu rozwiązania i w przypadku P2017 było kilka postów, ale różne przyczyny od wymiany kolektora, po jego czyszczenie bądź nieszczelność.
Wyskakuje mi co jakiś czas znany i lubiany komunikat "Awaria.." raz po usunięciu błędów auto długo nie widziało już żadnego problemu a potem znów wyświetlało się..
błędy które mi odczytało:
P2017-08 - wysokie napięcie w obwodzie sygnału zwrotnego zaworu regulacyjnego kanału ssącego kolektora dolotowego
błąd ogólny: Nieprawidłowy sygnał
Statuses: Supported By Calibration, Obecny..
P2015-22 - Działanie wewnętrznego elementu nastawczego zaworu regulacyjnego kanału ssącego kolektora dolotowego
Błąd sygnału: zwarcie do masy
Statuses: Supported by calibration..
Zczytane przez opl dtc reader lub opl monitor już nie pamiętam - ale potwierdzone również u znajomego co ma jakiś tam interfejs wpinany do kompa, czyt. ogólnie lepszy niż elm czy tam vlink
Pytanie czy ktoś miał już do czynienia z takimi problemami? O czym one świadczą? Co jest do naprawy? wymiany?
Prosiłbym o pomoc

DTC Descriptors
DTC P2016 08: Intake Manifold Runner Control Valve Feedback Circuit Low Voltage
DTC P2017 08: Intake Manifold Runner Control Valve Feedback Circuit High Voltage
The position of the swirl flaps is controlled by the engine control module (ECM). The ECM controls the intake manifold runner control solenoid valve to create a swirl in the combustion chamber to get a homogeneous diesel air mixture. The ECM will vary the intake manifold runner control solenoid valve referring to the barometric pressure and the mass air flow. The ECM uses a pulse width modulation on the control circuit to control the intake manifold runner control solenoid valve.
Conditions for Running the DTC
Engine is running
Conditions for Setting the DTC
P2016
The ECM detects a short to ground or an open circuit for more than 5 s.
P2017
The ECM detects a short to voltage for more than 5 s.
Action Taken When the DTC Sets
DTCs P2016 and P2017 are Type A DTCs.
Conditions for Clearing the DTC
DTCs P2016 and P2017 are Type A DTCs.

Circuit/System Verification
Ignition ON, command the Intake Manifold Runner ON and OFF with a scan tool. Observe the Intake Manifold Runner Control Valve Feedback Signal parameter.
Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
Ignition OFF, disconnect the harness connector at the Q21 Intake Manifold Runner Control Solenoid Valve.
Test for less than 5 Ω between the low reference circuit terminal 2 and ground.
If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K20 Engine Control Module.
Disconnect the X1 harness connector at the K20 Engine Control Module.
Ignition ON, test for less than 0.3 V between the signal circuit at the Q21 Intake Manifold Runner Control Solenoid Valve terminal 5 and ground.
If greater than the specified range, test the signal circuit for a short to voltage.
Ignition OFF, test for greater than 500 kΩ between the signal circuit terminal 5 and ground.
If less than the specified range, test the signal circuit for a short to ground.
Test for less than 5 Ω between the signal circuit at the Q21 Intake Manifold Runner Control Solenoid Valve terminal 5 and the signal circuit at the K20 Engine Control Module terminal listed below.
• LCD/LBX/LBS Terminal 43 X1
• LBY Terminal 91 X1
If greater than the specified range, test the signal circuit for an open circuit. If the circuit tests normal, replace the K20 Engine Control Module.
If all circuits test normal, replace the Q21 Intake Manifold Runner Control Solenoid Valve and verify the DTC does not reset.
If the DTC resets, replace the K20 Engine Control Module.

Problem z działaniem klapek w kolektorze ssącym. Ja bym najpierw sprawdził wtyczkę przy sterowniku oraz przewody połączeniowe. Procedura co i jak i jakie parametry powinny być są opisane w powyższych linkach.
Problem rozwiązany - usunięcie klap kolektora, zaślepienie EGR (przy okazji) i wyprogramowanie tego z kompa. Operacja u dobrego mechanika w ciągu kilku godzin.. I jak ręką odjął, ponadto DPF wypala się rzadziej, +200-300 km
