DTC P0013: Camshaft Position "B" Actuator Circuit / Open (Bank 1) (TO 12/2010); DTC P0023: Camshaft Position "B" Actuator Circuit / Open (Bank 2) (TO 12/2010): Procedure

WARNING: This page is about a different car, the 2011 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

PERFORM ACTIVE TEST USING TECHSTREAM (CONTROL THE VVT EXHAUST LINEAR (BANK 1 OR BANK 2))

Connect Techstream to the DLC3.
Start the engine and turn the Techstream on.
Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank1) or Control the VVT Exhaust Linear (Bank2).

Check the engine speed while operating the Oil Control Valve (OCV) using the Techstream.

Techstream Operation	Specified Condition
-128% (OCV OFF)	Normal engine speed
127% (OCV ON)	Engine idles roughly or stalls (soon after OCV switched from OFF to ON)

NG → See step 3

OK → See step 2

CHECK FOR INTERMITTENT PROBLEMS. Refer to CHECK FOR INTERMITTENT PROBLEMS

INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT)

Remove the OCV for exhaust camshaft.

Measure the resistance between the terminals of the OCV.

Standard resistance

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

Connect the positive (+) battery terminal to terminal 1 and connect the negative (-) battery terminal to terminal 2. Check the valve operation.
OK

Valve moves quickly.

Reinstall the OCV.

NG → REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT)

OK: Go to next step

CHECK HARNESS AND CONNECTOR (OCV - ECM)

Disconnect the OCV for exhaust camshaft connector.
Disconnect the ECM connector.

Measure the resistance between the terminals.

Standard resistance (Check for open)

Tester Connection	Condition	Specified Condition
B50-16 (OE1+) - B43-1	Always	Below 1 Ω
B50-17 (OE1-) - B43-2	Always	Below 1 Ω
B50-14 (OE2+) - B20-1	Always	Below 1 Ω
B50-15 (OE2-) - B20-2	Always	Below 1 Ω

Standard resistance (Check for short)

Tester Connection	Condition	Specified Condition
B50-16 (OE1+) or B43-1 - Body ground	Always	10 kΩ or higher
B50-17 (OE1-) or B43-2 - Body ground	Always	10 kΩ or higher
B50-14 (OE2+) or B20-1 - Body ground	Always	10 kΩ or higher
B50-15 (OE2-) or B20-2 - Body ground	Always	10 kΩ or higher

Reconnect the ECM connector.
Reconnect the OCV connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (OCV - ECM)

OK → See step 5

REPLACE ECM. Refer to REMOVAL
