Circuit/System Description
The camshaft position actuator solenoid valve - inlet and
camshaft position actuator solenoid valve - exhaust are attached to
each camshaft and is operated hydraulically in order to change the
angle of the camshaft relative to crankshaft position. The camshaft
position actuator solenoid valve - inlet and camshaft position
actuator solenoid valve - exhaust are controlled by the engine
control module (ECM). The ECM sends a pulse width modulated
signal to a camshaft position actuator solenoid valve - inlet and
camshaft position actuator solenoid valve - exhaust solenoids. The
camshaft position actuator solenoid valve - inlet and camshaft
position actuator solenoid valve - exhaust solenoids controls the
amount of engine oil flow to a camshaft position actuator solenoid
valve - inlet and camshaft position actuator solenoid valve -
exhaust. The camshaft position actuator solenoid valve - inlet and
camshaft position actuator solenoid valve - exhaust can change the
camshaft angle by a maximum of 20°. The ECM increases the pulse
width to accomplish the desired camshaft operation.
The ECM controls the solenoid with a solid state device called a
driver. The driver is equipped with a feedback circuit that is
pulled-up to a voltage. The ECM can determine if the control
circuit is open, shorted to ground, or shorted to a voltage by
monitoring the feedback voltage.
Conditions for Running the DTC
• |
DTC P0010 00, P0013 00, P0016 00,
P0017 00, P0335 00, P0336 00, P0340 00,
P0341 00, P0365 00, or P0366 00 is not set. |
• |
The ignition voltage is between 11-18 V. |
• |
The camshaft position actuator is enabled. |
• |
The rate of change in the camshaft position is
less than 5° for 4 s. |
Conditions for Setting the DTC
The ECM detects a difference of greater than 8° between the
camshaft position angle position and the desired camshaft position
for greater than 30 s.
Action Taken When the DTC Sets
• |
DTCs P0011 00 and P0014 00 are
Type B DTCs. |
• |
The camshaft position actuator solenoid valve -
inlet and camshaft position actuator solenoid valve - exhaust are
commanded to the park position. |
Conditions for Clearing the DTC
DTCs P0011 00 and P0014 00 are Type B DTCs.
Diagnostic Aids
• |
The engine oil condition has a major impact on the
camshaft actuator system. |
• |
A low oil level condition may set this DTC. The
engine may require an oil change. Inquire with the customer when
the last oil change was performed. You may also monitor the scan
tool Engine Oil Life Remaining parameter. Advise the customer an
oil change may be required. |
• |
Inspect the engine for any recent engine
mechanical repairs. An incorrectly installed camshaft, camshaft
actuator, or timing belt can cause this DTC to set. |
• |
A resistance greater than 8 Ω on the camshaft
position actuator solenoid valve - intake or camshaft position
actuator solenoid valve - exhaust control circuit may set this DTC.
If you suspect high resistance, ground the control circuit while
the engine is idling. The scan tool Inlet Camshaft Position
Actuator Solenoid Valve Control Circuit Low Voltage Test Status or
Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit
Low Voltage Test Status parameter should display Fault. If the
parameter displays OK, test the control circuit for high
resistance. |

Circuit/System Verification
Note: The engine oil level and
the oil pressure are critical to the correct operation of the
camshaft position actuator system. Verify that the engine has the
correct oil level and the correct oil pressure before continuing
with this diagnostic.
Refer to
Engine Mechanical Specifications .
- Engine idling at operating temperature, command the
appropriate Inlet Camshaft Position Actuator or Exhaust Camshaft
Position Actuator to 20° with a scan tool. The Desired Intake
Camshaft Position or Desired Exhaust Camshaft Position parameter
value should match the Intake Camshaft Position or Exhaust Camshaft
Position angle parameter value.
- Observe the Inlet Camshaft Position Variance or
Exhaust Camshaft Position Variance value on the scan tool. The
Inlet Camshaft Position Variance or Exhaust Camshaft Position
Variance value will increment for several seconds until the Inlet
Camshaft Position or Exhaust Camshaft Position angle value matches
the Desired Inlet Camshaft Position or Desired Exhaust Camshaft
Position value. The Inlet Camshaft Position Variance or Exhaust
Camshaft Position Variance value should then return to 0°.
- Operate the vehicle within the conditions for running
the DTC. You may also operate the vehicle within the conditions
that you observed from the freeze frame/failure records data.
Circuit/System Testing
- Ignition OFF for 1 min, disconnect the harness
connector at the appropriate Q6F Camshaft Position Actuator
Solenoid Valve - Intake or Q6E Camshaft Position Actuator
Solenoid Valve - Exhaust solenoid.
- Test for less than 5 Ω between the low reference
circuit terminal 1 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. |
- Ignition ON, test for 2-3 V between the control
circuit terminal 2 and ground.
⇒ |
If less than the specified range, test the control
circuit for a short to ground or an open/high resistance. If the
circuit tests normal, replace the K20 Engine Control
Module. |
⇒ |
If greater than the specified range, test the
control circuit for a short to voltage. If the circuit/connections
test normal, replace the K20 Engine Control Module. |
- Command the appropriate Intake Camshaft Position
Actuator Solenoid Valve or Exhaust Camshaft Position Actuator
Solenoid Valve solenoid ON and OFF with a scan tool. The DMM should
transition from 2-3 V when commanded OFF to greater than
10 V when commanded ON.
⇒ |
If the circuit voltage does not correspond to the
specified values, replace the K20 Engine Control Module. |
- Remove the Q6F Camshaft Position Actuator
Solenoid Valve - Intake or Q6E Camshaft Position Actuator
Solenoid Valve - Exhaust solenoid. Inspect the appropriate camshaft
position actuator solenoid valve and mounting area for the
following conditions:
• |
For torn, restricted, mis-positioned, or missing
screens at the Q6F Camshaft Position Actuator Solenoid Valve -
Intake or Q6E Camshaft Position Actuator Solenoid Valve -
Exhaust |
• |
For engine oil leaks between the oil sealing lands
of the Q6F Camshaft Position Actuator Solenoid Valve - Intake
or Q6E Camshaft Position Actuator Solenoid Valve - Exhaust
solenoid, inspect the lands of the Q6F Camshaft Position
Actuator Solenoid Valve - Intake or Q6E Camshaft Position
Actuator Solenoid Valve - Exhaust solenoid for nicks |
• |
Remove the Q6F Camshaft Position Actuator
Solenoid Valve - Intake or Q6E Camshaft Position Actuator

Q6F Camshaft Position Actuator Solenoid Valve - Intake or
Q6E Camshaft Position Actuator Solenoid Valve - Exhaust
solenoid. |
- Ignition OFF, swap the suspected Q6F Camshaft
Position Actuator Solenoid Valve - Intake or Q6E Camshaft
Position Actuator Solenoid Valve - Exhaust solenoid with a
Q6F Camshaft Position Actuator Solenoid Valve - Intake or
Q6E Camshaft Position Actuator Solenoid Valve - Exhaust
actuator solenoid that is operating correctly.
Note: This step is testing the
mechanical operation of the camshaft position actuator solenoid
valve that set the DTC.
- Engine idling, command the appropriate Inlet Camshaft
Position Actuator or Exhaust Camshaft Position Actuator to 20°
and back to 0° while observing the appropriate scan tool Inlet
Camshaft Position Variance or Exhaust Camshaft Position Variance
value parameter. The Inlet Camshaft Position Variance or Exhaust
Camshaft Position Variance value should be less than 2° in each
of the commanded states.
⇒ |
If greater than the specified value, replace or
repair the mechanical camshaft position actuator operation. |
