P0013

1UR-FSE 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 Variable Valve Timing (VVT) system adjusts the exhaust 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 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.

CONFIRMATION DRIVING PATTERN





1. Connect the Techstream to the DLC3.

2. Turn the engine switch on (IG) and turn the Techstream on.

3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) Reading and Clearing Diagnostic Trouble Codes.

4. Turn the engine switch off and wait for 30 seconds.

5. Turn the engine switch on (IG) and turn the Techstream on.

6. Wait 5 seconds [A].

7. Enter the following menus: Powertrain / Engine / Trouble Codes.

8. Read the DTC [B].

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

9. Enter the following menus: Powertrain / Engine / 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.
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result sows INCOMPLETE or UNKNOWN, perform step [A] again.

12. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

13. Check the DTC judgment result.

HINT
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows NORMAL, the system is normal.

14. If the test result is INCOMPLETE or UNKNOWN and no 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 side circuit.
- Bank 1 refers to the bank that includes 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 side 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.

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 engine switch off and wait 30 seconds.

(d) Start the engine and allow the engine to idle and check DTC.

(e) Check that P0013 or P0023 is present.

OK:

NO DTC output

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) Remove the OCV Removal.





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

Standard resistance:





(c) Reinstall the OCV.

NG -- REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY Components
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 (Check for Open):





Standard Resistance (Check for Short):





(d) Reconnect the OCV and ECM connectors.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE ECM Components
