P0013

1GR-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 timing oil control valve (OCV) assembly 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 exhaust valve timing to improve the driveability. The engine oil pressure turns the camshaft timing exhaust gear assembly 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.









MONITOR DESCRIPTION

This DTC is designed to detect opens or shorts in the camshaft oil control valve (OCV) circuit. If the OCV duty-cycle is excessively high or low while 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 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.

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

8. Read the DTCs.

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 and ECT / 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 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
* Read freeze frame data using the Techstream. Freeze frame data records the engine condition when malfunctions are detected. 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.
* If DTC P0013 is output, check the bank 1 VVT system for exhaust side 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.
* If DTC P0023 is output, check the bank 2 VVT system for exhaust side circuit.
* Bank 2 refers to the bank that does not include the No. 1 cylinder.

PROCEDURE

1. CHECK WHETHER DTC OUTPUT RECURS (DTC P0013 OR P0023)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

(e) Start the engine and warm it up.

(f) Allow the engine to idle 1 minute or more.

(g) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

(h) Read DTCs.

B -- CHECK FOR INTERMITTENT PROBLEMS Check for Intermittent Problems
A -- Continue to next step.

2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST SIDE)

(a) Disconnect the camshaft timing oil control valve (for exhaust side).





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

Standard Resistance:

NG -- REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST SIDE) Removal
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (OCV FOR EXHAUST SIDE - ECM)

(a) Disconnect the camshaft timing oil control valve (for exhaust side).

(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):





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE ECM Removal
