DTC P0010: Camshaft Position "A" Actuator Circuit (Bank 1): Procedure

1. Connect the Techstream to the DLC3.
2. Start the engine.
3. Turn the Techstream on.
4. Turn the A/C switch on.
5. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Linear (Bank 1).
6. Check the engine speed while operating the camshaft timing oil control valve assembly (for intake camshaft) using the Techstream.

   Result

   Techstream Operation	Specified Condition
   0%	Normal engine speed
   100%	Engine idles roughly or stalls

   OK

   Valve moves quickly.

4. Reinstall the camshaft timing oil control valve assembly (for intake camshaft).

NG → See step   5 

OK: Go to next step 

1. Disconnect the camshaft timing oil control valve assembly (for intake camshaft) connector.
2. Disconnect the ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance (Check for Open)

   Tester Connection	Condition	Specified Condition
   B25-1 - B49-28 (OC1+)	Always	Below 1 Ω
   B25-2 - B49-22 (OC1-)	Always	Below 1 Ω

   Standard Resistance (Check for Short)

   Tester Connection	Condition	Specified Condition
   B25-1 or B49-28 (OC1+) - Body ground	Always	10 kΩ or higher
   B25-2 or B49-22 (OC1-) - Body ground	Always	10 kΩ or higher

4. Reconnect the camshaft timing oil control valve assembly (for intake camshaft) connector.
5. Reconnect the ECM connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
