2ZR-FE ENGINE CONTROL: SFI SYSTEM: P0013: Camshaft Position "B" Actuator Circuit / Open (Bank 1)

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

DESCRIPTION

The VVT (variable valve timing) system adjusts the exhaust valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.
The camshaft timing oil control valve is a solenoid valve and switches the engine oil line. The valve moves when the ECM applies 12 V to the solenoid. The ECM changes the energizing time to the solenoid (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.









MONITOR DESCRIPTION

This DTC is designed to detect open or short circuits in the camshaft timing oil control valve (for exhaust camshaft) circuit. If the camshaft timing oil control valve assembly's duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and set the DTC.

INSPECTION PROCEDURE
HINT:
- If DTC P0013 is displayed, check the VVT system (for exhaust camshaft) circuit.
- Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

PROCEDURE

1. PERFORM ACTIVE TEST USING USING TECHSTREAM (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE)
(a) Connect the Techstream to the DLC3.
(b) Start the engine.
(c) Turn the Techstream on.
(d) Turn the A/C switch to ON.
(e) Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT Exhaust Linear (Bank 1).
(f) Check the engine speed while operating the camshaft timing oil control valve assembly (for exhaust camshaft) using the Techstream.
Result:





HINT: If the result is not acceptable, cool the engine and perform the Active Test again.
(g) Start the engine when the engine coolant temperature is 30°C (86°F) or less.
(h) Turn the Techstream on.
(i) Turn the A/C switch to ON.
(j) Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT Exhaust Linear (Bank 1).
(k) Check the engine speed while operating the camshaft timing oil control valve assembly (for exhaust camshaft) using the Techstream with the engine coolant temperature is 50°C (122°F) or less.
Result:






NG -- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT)
OK -- CHECK FOR INTERMITTENT PROBLEMS
2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT)




(a) Remove the camshaft timing oil control valve assembly (for exhaust camshaft).
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:









(c) Apply battery voltage to terminals of the camshaft timing oil control valve assembly (for exhaust camshaft). Check the valve operation.
OK:
Valve moves quickly.
(d) Reinstall the camshaft timing oil control valve assembly (for exhaust camshaft).
NG -- REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT)
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY - ECM)




(a) Disconnect the camshaft timing oil control valve assembly (for exhaust camshaft) connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance (Check for Open):






Standard Resistance (Check for Short):





(d) Reconnect the camshaft timing oil control valve assembly (for exhaust camshaft) connector.
(e) Reconnect the ECM connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY - ECM)
OK -- REPLACE ECM
