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
• |
The ignition voltage is between 11-18 V. |
• |
The camshaft position actuator is commanded
on. |
• |
The DTCs run continuously when the above
conditions are met. |
Conditions for Setting the DTC
The ECM detects that the commanded state of the driver and the
actual state of the control circuit do not match for greater than
5 s.
Action Taken When the DTC Sets
DTCs P0010 00, and P0013 00, are Type B
DTCs.
Conditions for Clearing the DTC
DTCs P0010 00, and P0013 00, are Type B
DTCs.
Diagnostic Aids
If the condition is intermittent, move the related harnesses and
connectors, with the engine operating, while monitoring the scan
tool Camshaft Position Sensor solenoid circuit status parameters.
The circuit status parameters will change from OK, or Not Run, to
Fault if there is a condition with the circuit or connection.

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 .
- Ignition ON, command the appropriate Intake Camshaft
Position Actuator Solenoid Valve or Exhaust Camshaft Position
Actuator Solenoid Valve ON and OFF with a scan tool. You should
hear the solenoid click when commanded ON and OFF.
- Engine idling, observe the following scan tool control
circuit status parameters:
• |
Intake Camshaft Position Actuator Solenoid Valve
Control Circuit High Voltage Test Status |
• |
Intake Camshaft Position Actuator Solenoid Valve
Control Circuit Open Test Status |
• |
Intake Camshaft Position Actuator Solenoid Valve
Control Circuit Low Voltage Test Status |
• |
Exhaust Camshaft Position Actuator Solenoid Valve
Control Circuit High Voltage Test Status |
• |
Exhaust Camshaft Position Actuator Solenoid Valve
Control Circuit Open Test Status |
• |
Exhaust Camshaft Position Actuator Solenoid Valve
Control Circuit Low Voltage Test Status |
|
Each parameter should display OK or Not Run. |
- 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. |
- If all circuits/connections test normal, test or
replace the Q6F Camshaft Position Actuator Solenoid Valve -
Intake or Q6E Camshaft Position Actuator Solenoid Valve -
Exhaust.
Component Testing
Static Test
- Ignition OFF, disconnect the harness connector at the
appropriate Q6F Camshaft Position Actuator Solenoid Valve -
Inlet or Q6E Camshaft Position Actuator Solenoid Valve -
Exhaust.
- Test for 7-12 Ω between the terminals of the
Q6F Camshaft Position Actuator Solenoid Valve - Intake or
Q6E Camshaft Position Actuator Solenoid Valve - Exhaust
solenoid.
⇒ |
If not within the specified range, replace the
Q6F Camshaft Position Actuator Solenoid Valve - Intake or
Q6E Camshaft Position Actuator Solenoid Valve - Exhaust
solenoid. |
- Test for infinite resistance between each terminal and
the appropriate Q6F Camshaft Position Actuator Solenoid Valve
- Intake or Q6E Camshaft Position Actuator Solenoid Valve -
Exhaust housing.
⇒ |
If not the specified value, replace the
Q6F Camshaft Position Actuator Solenoid Valve - Intake or
Q6E Camshaft Position Actuator Solenoid Valve - Exhaust
solenoid. |
