P0013

3UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0013, P0023: Camshaft Position "B" Actuator Circuit / Open (Bank 1)
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 set 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.

CONFIRMATION DRIVING PATTERN





1. Connect Techstream to the DLC3.

2. Turn the ignition switch to ON and turn the Techstream on.

3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).

4. Turn the ignition switch off and wait for at least 30 seconds.

5. Turn the ignition switch to ON and turn the Techstream on.

6. Wait 5 seconds [A].

7. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [B].

8. Read the Pending DTCs.

HINT
* If a pending DTC is output, the system is malfunctioning.
* If a pending DTC is not output, perform the following procedure.

9. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

10. Input the DTC: P0013 or P0023.

11. Check the DTC judgment result.





HINT
If the judgment result shows ABNORMAL, the system has a malfunction.

12. If the test result is INCOMPLETE or UNKNOWN and no pending DTC is output, perform a universal trip and check for permanent DTCs Reading and Clearing Diagnostic Trouble Codes.

HINT
* If a permanent DTC is output, the system is malfunctioning.
* If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

HINT
* If DTC P0013 is displayed, check the bank 1 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 moving or stationary, 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 Reading and Clearing Diagnostic Trouble Codes.
* Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from the transmission.
* 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 the No. 1 cylinder.

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 TIMING OIL CONTROL VALVE ASSEMBLY

OK -- CHECK FOR INTERMITTENT PROBLEMS Check for Intermittent Problems

2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

(a) Disconnect the D44 or D45 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 TIMING OIL CONTROL VALVE ASSEMBLY Removal
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (OCV - ECM)

(a) Disconnect the D44 or D45 OCV connector.





(b) Disconnect the D74 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 Removal
