Circuit/System Description
The position of the swirl flaps is controlled by the engine
control module (ECM). The ECM controls the inlet 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
inlet 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 inlet
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 Inlet 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 Inlet 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 Inlet 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 43 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. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
