Circuit/System Description
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
| 1. |
Ignition ON, command the
Intake Manifold Runner ON and OFF with a scan tool. Observe the
Intake Manifold Runner Control Valve Feedback Signal
parameter. |
| 2. |
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
| 1. |
Ignition OFF, disconnect the
harness connector at the Q21 Intake Manifold Runner Control
Solenoid Valve. |
| 2. |
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. |
| 3. |
Disconnect the X2 harness
connector at the K20 Engine Control Module. |
| 4. |
Ignition ON, test for less
than 0.3 V between the signal circuit at the Q21 Intake Manifold
Runner Control Solenoid Valve terminal 92 and ground. |
| ⇒ |
If greater than the specified range, test the
signal circuit for a short to voltage. |
| 5. |
Ignition OFF, test for greater
than 500 kΩ between the signal circuit terminal 92 and
earth. |
| ⇒ |
If less than the specified range, test the signal
circuit for a short to ground. |
| 6. |
Test for less than 5 Ω
between the signal circuit at the Q21 Intake Manifold Runner
Control Solenoid Valve terminal 2 and the signal circuit at the K20
Engine Control Module terminal 92. |
| ⇒ |
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. |
| 7. |
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.
