I have a 2006 2.4L, my check engine light kept coming on so i put it on my uncle's computer and it spit out P0010/the intake Camshaft Position Actuator Circuit is open (Bank 1) i know what that is i just don't know where it is at or even how it got open, any ideas???

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 Oil Pressure Diagnosis and Testing.

• The engine oil condition has a major impact on the camshaft actuator system. Debris in the oil can interfere with the camshaft position actuator solenoid and the mechanical camshaft actuator operation. Inspect for dirty or degraded crankcase oil. 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.

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

Circuit/System Testing
•Ignition OFF, disconnect the harness connector at the appropriate Camshaft Position Actuator Solenoid Valve.
•Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down. Test for less than 5 Ω between the low reference circuit terminal B and ground.
⇒ If greater than the specified value, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ECM.

Note: A test lamp must be used for this test. The control circuit is pulled-up to a low current voltage, a voltage on the control circuit is normal.

•Ignition ON, verify that a test lamp does not illuminate between the control circuit terminal A and ground.
⇒ If the test lamp illuminates, test the control circuit for a short to voltage. If the circuit tests normal, replace the ECM.

•Connect the DMM black lead to the control circuit terminal A. Connect the DMM red lead to B+. Set the DMM on the diode setting. Command the CMP actuator solenoid ON and OFF with a scan tool. The DMM should transition from 2.5-3.5 V when commanded OFF to less than 1 V when commanded ON.
⇒ If the circuit voltage does not correspond to the specified values, test the control circuit for an open/high resistance or a short to ground. If the circuit tests normal, replace the ECM.

•Remove the Camshaft Position Actuator Solenoid Valve. Verify the following conditions do not exist with the Camshaft Position Actuator Solenoid Valve:
• Torn, restricted, mis-positioned, or missing screens at the CMP actuator solenoid

• Engine oil leak between the oil sealing lands of the CMP actuator solenoid. Inspect the lands of the CMP actuator solenoid for nicks.

• Oil seepage at the CMP actuator solenoid connector

⇒ If a condition is found, replace Camshaft Position Actuator Solenoid Valve.

•Ignition OFF, swap the appropriate Camshaft Position Actuator Solenoid Valve with a Camshaft Position Actuator Solenoid Valve that is operating correctly.
•Engine idling. Command the appropriate Camshaft Position Actuator from 0 degrees to 20 degrees and back to zero while observing the appropriate scan tool Camshaft Position Variance parameters. The Camshaft Position Variance should be less than 2 degrees in each of the commanded states.
⇒ If greater than the specified value, replace the mechanical camshaft position actuator.

•If all circuits/connections test normal, test or replace the Camshaft Position Actuator Solenoid Valve.
Component Testing
•Ignition OFF, disconnect the harness connector at the Camshaft Position Actuator Solenoid Valve.
•Test for 8-12 Ω between the control terminal A and the low reference circuit terminal B of the Camshaft Position Actuator Solenoid Valve.
⇒ If not within the specified range, replace the Camshaft Position Actuator Solenoid Valve.

•Test for infinite resistance between each terminal and the Camshaft Position Actuator Solenoid Valve housing.
