P0013
4GR-FSE ENGINE CONTROL: SFI SYSTEM: P0013, P0023: Camshaft Position "B" Actuator Circuit / Open (Bank 1)
P0023 - Camshaft Position "B" Actuator Circuit / Open (Bank 2)
DESCRIPTION
The Variable Valve Timing (VVT) 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 assembly 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 an open or short in the camshaft timing oil control valve assembly (for exhaust camshaft) circuit. If the camshaft timing oil control valve assembly duty-cycle is excessively high or low while the engine switch on (IG) or the engine is running, the ECM will illuminate the MIL and store the DTC.

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 operation) Reading and Clearing Diagnostic Trouble Codes.
4. Turn the engine switch off and wait for at least 30 seconds.
5. Turn the engine switch on (IG) and turn the Techstream on [A].
6. Wait 5 seconds.
7. Enter the following menus: Powertrain / Engine / Trouble Code [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 / Utility / All Readiness.
10. Input the DTC: P0013 or P0023.
11. Check the DTC judgment result.
HINT
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
12. If the judgment result is INCOMPLETE or N/A 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.
- If DTC P0023 is displayed, check the bank 2 VVT system for exhaust camshaft circuit.
- 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.
- Bank 2 refers to the bank that does not include the 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 help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1. CHECK DTC (DTC P0013 OR P0023)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Read the DTCs.
Result:
B -- PERFORM ACTIVE TEST USING TECHSTREAM (CONTROL THE VVT EXHAUST LINEAR (BANK 2))
A -- Continue to next step.
2. PERFORM ACTIVE TEST USING TECHSTREAM (CONTROL THE VVT EXHAUST LINEAR (BANK 1))
(a) Connect the Techstream to the DLC3.
(b) Start the engine.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank 1).
(e) Check the engine speed while operating the camshaft timing oil control valve assembly using the Techstream.
OK:
HINT
Refer to "Data List / Active Test" [VVT Ex OCV Duty #1, VVT Ex Chg Angle #1, VVT Ex OCV Duty #2 and VVT Ex Chg Angle #2] Data List / Active List.
NG -- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT)
OK -- CHECK FOR INTERMITTENT PROBLEMS Check for Intermittent Problems
3. PERFORM ACTIVE TEST USING TECHSTREAM (CONTROL THE VVT EXHAUST LINEAR (BANK 2))
(a) Connect the Techstream to the DLC3.
(b) Start the engine.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank 2).
(e) Check the engine speed while operating the camshaft timing oil control valve assembly using the Techstream.
OK:
HINT
Refer to "Data List / Active Test" [VVT Ex OCV Duty #1, VVT Ex Chg Angle #1, VVT Ex OCV Duty #2 and VVT Ex Chg Angle #2] Data List / Active List.
NG -- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT)
OK -- CHECK FOR INTERMITTENT PROBLEMS Check for Intermittent Problems
4. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT)
(a) Inspect the camshaft timing oil control valve assembly (for exhaust camshaft) Inspection.
NG -- REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT) Removal
OK -- Continue to next step.
5. 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.
