DTC P0013: Camshaft Position "B" Actuator Circuit / Open (Bank 1): Procedure

WARNING: This page is about a different variant/trim than selected.

PERFORM ACTIVE TEST USING USING TECHSTREAM (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE)

Connect the Techstream to the DLC3.
Start the engine.
Turn the Techstream on.
Turn the A/C switch on.
Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank 1).

Check the engine speed while operating the camshaft timing oil control valve assembly (for exhaust camshaft) using the Techstream.

Result

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

NG → See step 2

OK → See step 4

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

Remove the camshaft timing oil control valve assembly (for exhaust camshaft).

OK

Valve moves quickly.
Reinstall the camshaft timing oil control valve assembly (for exhaust camshaft).

NG → See step 5

OK: Go to next step

CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY - ECM)

Disconnect the camshaft timing oil control valve assembly (for exhaust camshaft) connector.
Disconnect the ECM connector.

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

Standard Resistance (Check for Open)

Tester Connection	Condition	Specified Condition
B64-1 - B50-25 (OE1+)	Always	Below 1 Ω
B64-2 - B50-19 (OE1-)	Always	Below 1 Ω

Standard Resistance (Check for Short)

Tester Connection	Condition	Specified Condition
B64-1 or B50-25 (OE1+) - Body ground	Always	10 kΩ or higher
B64-2 or B50-19 (OE1-) - Body ground	Always	10 kΩ or higher

Reconnect the camshaft timing oil control valve assembly (for exhaust camshaft) connector.
Reconnect the ECM connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY - ECM)

OK → See step 6

CHECK FOR INTERMITTENT PROBLEMS. Refer to CHECK FOR INTERMITTENT PROBLEMS
REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT). Refer to REMOVAL
