P0013

3UR-FE ENGINE CONTROL: SFI SYSTEM: P0013: Camshaft Position "B" Actuator Circuit / Open (Bank 1)

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

DTC P0023 - Camshaft Position "B" Actuator Circuit / Open (Bank 2)

DESCRIPTION

- This DTC is designed to detect opens or shorts in the camshaft oil control valve (OCV) circuit. If the OCV's duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and store the DTC.
- The VVT (variable valve timing) system adjusts the intake valve timing to improve the driveability. The engine oil pressure turns the camshaft actuator to adjust the valve timing. The OCV is a solenoid valve and switches the engine oil line. The valve moves when the ECM applies 12 volts 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.

INSPECTION PROCEDURE

HINT:
- If DTC P0013 is displayed, check the bank 1 VVT system for exhaust camshaft circuit.
- Bank 1 refers to the bank that includes No. 1 cylinder.
- If DTC P0023 is displayed, check the bank 2 VVT system for exhaust camshaft circuit.
- Bank 2 refers to the bank that does not include No. 1 cylinder.
- 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 DTC Check / Clear.

PROCEDURE

1. CHECK DTC (DTC P0013 OR P0023)
(a) Connect the Techstream to the DLC3.
(b) Clear DTC after recording the freeze frame data and DTC.
(c) Turn the ignition switch off.
(d) Allow the engine to idle and check DTC.
(e) Check that P0013 or P0023 is not present.
OK:
P0013 or P0023 is not present.

NG -- INSPECT CAMSHAFT OIL CONTROL VALVE ASSEMBLY
OK -- CHECK FOR INTERMITTENT PROBLEMS
2. INSPECT CAMSHAFT OIL CONTROL VALVE ASSEMBLY





(a) Disconnect the OCV connector.
(b) Remove the OCV Removal.
(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPLACE CAMSHAFT OIL CONTROL VALVE ASSEMBLY
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (OCV - ECM)





(a) Disconnect the OCV connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE ECM
