Circuit/System Verification
NOTE
Record all Failure Records before clearing
the DTC. Using Clear Info erases the Failure
Records from the engine control module
(ECM) and transmission control module
(TCM).
1. Ignition ON, record the DTC Freeze Frame/Failure
Records.
➢ If any TCM Freeze Frame/Failure Records are
recorded refer to"Diagnostic Trouble Code (DTC)
List - Vehicle Diagnostic Information: ".
2. Clear the DTC information with a scan tool.
3. Ignition OFF for at least 30 seconds.
4. Engine idling for 1 minute. DTC P0864 should not
set.
➢ If DTC P0864 sets and no TCM DTCs are present,
replace the ECM.
➢ If DTC P0864 and TCM DTCs are set, refer to
"Diagnostic Trouble Code (DTC) List - Vehicle
Diagnostic Information: "

DTC Descriptor
DTC P1011: Intake Camshaft Position (CMP) Actuator
Park Position Bank 1
DTC P1012: Exhaust Camshaft Position (CMP)
Actuator Park Position Bank 1
DTC P1013: Intake Camshaft Position (CMP) Actuator
Park Position Bank 2
DTC P1014: Exhaust Camshaft Position (CMP)
Actuator Park Position Bank 2
Circuit/System Description
The camshaft position (CMP) actuator system enables
the engine control module (ECM) to change the
camshaft timing of all 4 camshafts while the engine is
operating. The CMP actuator assembly varies the
camshaft position in response to directional changes in
oil pressure. The CMP actuator solenoid controls the oil
pressure that is applied to advance or retard a camshaft.
The CMP actuator assemblies have an outer housing
that is driven by the engine timing chain. Inside the CMP
assembly is a wheel with fixed vanes that is attached to
the camshafts. The CMP actuator assemblies are also
equipped with a locking pin. The locking pin prevents
movement between the outer housing and the wheel
vane assembly on engine start-ups. The CMP actuator is
locked until sufficient oil pressure is available to control
the CMP actuator. The locking pin is released by oil
pressure before any movement in the CMP actuator
assembly takes place.
Conditions for Running the DTC
• DTCs P0010, P0013, P0020, P0023, P2088, P2089,
P2090, P2091, P2092, P2093, P2094, and P2095 are
not set.
• The engine is operating for more than 1 second.
• The ECM completed the CMP actuator solenoid
output driver test.
• The engine speed is more than 1,000 RPM.
• DTCs P1011, P1012, P1013, and P1014 only run
once at engine start-up.
