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 to ON.
5. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT System (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
   OFF	Normal engine speed
   ON	Engine idles roughly or stalls (soon after camshaft timing oil control valve assembly switched from OFF to ON)

   HINT: 

   If the result is not acceptable, cool the engine and perform the Active Test again.

7. Start the engine when the engine coolant temperature is 30°C (86°F) or less.
8. Turn the Techstream on.
9. Turn the A/C switch to ON.
10. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT System (Bank 1).
11. Check the engine speed while operating the camshaft timing oil control valve assembly (for intake camshaft) using the Techstream with the engine coolant temperature is 50°C (122°F) or less.

    Result

    Techstream Operation	Specified Condition
    OFF	Normal engine speed
    ON	Engine idles roughly or stalls (soon after camshaft timing oil control valve assembly switched from OFF to ON)

2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   1 - 2	20°C (68°F)	6.9 to 7.9 Ω

3. Apply battery voltage to terminals of the camshaft timing oil control valve assembly (for intake camshaft). Check the valve operation.

   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
   B41-1 - B29-100 (OC1+)	Always	Below 1 Ω
   B41-2 - B29-123 (OC1-)	Always	Below 1 Ω

   Standard Resistance (Check for Short)

   Tester Connection	Condition	Specified Condition
   B41-1 or B29-100 (OC1+) - Body ground	Always	10 kΩ or higher
   B41-2 or B29-123 (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 (CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY - ECM)
