* DTCs P0010, P0013, P0020, and P0023 run continuously once 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, P0013, P0020, and P0023 are type B DTCs.



Conditions for Clearing the DTC



DTCs P0010, P0013, P0020, and P0023 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 circuit status



parameters for the component. The circuit status parameters change from OK or Not Run to Malfunction if there is a condition with the circuit or a



connection.

Circuit/System Verification



Note: If a crankshaft or camshaft position sensor DTC is set, the Camshaft Position Actuator output control will not function.



1. Ignition ON, observe the DTC information with a scan tool. Verify DTC P0335, P0336, P0340, P0341, P0345, P0346, P0365, P0366, P0390,



and P0391 is not set.



瀚慖f a DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic Trouble



Code (DTC) List - Vehicle) for further diagnosis.



2. Observe the appropriate control circuit status parameters listed below with a scan tool:



* The Intake/Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status Bank 1 or 2



* The Intake/Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit Open Test Status Bank 1 or 2



* The Intake/Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage Test Status Bank 1 or 2



Each parameter should display OK or Not Run



3. Engine idling, command the appropriate Camshaft Position Actuator from 0 degrees to 25 degrees and back to zero while observing the



appropriate control circuit status parameters listed below with a scan tool:
