P2614 - Camshaft Position Signal Output Circuit / Open

DESCRIPTION

Refer to DTC P0010 P0010.





CAMSHAFT CONTROL MOTOR SYMPTOMS AND FAIL-SAFE DURING MALFUNCTION





MONITOR DESCRIPTION

This DTC is output when a malfunction in the intake side camshaft timing control motor's rotation sensor is detected. The camshaft timing control motor is equipped with a self diagnostic function, which is used to output the duty ratio (when normal: 80%) as a signal (VTM) to the ECM. If the ECM receives a duty signal of 40%, a DTC is output immediately (1 trip detection logic). If the engine is idled for 10 seconds, a DTC is detected.

TYPICAL ENABLING CONDITIONS





TYPICAL MALFUNCTION THRESHOLDS





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 at least 30 seconds.

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

6. Wait 10 seconds.

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

8. Read the pending DTC.

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: P1023 or P2614.

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.

12. If the test 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
- 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 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. REPLACE CAMSHAFT TIMING CONTROL MOTOR (BANK 1 OR BANK 2)

(a) Replace the camshaft timing control motor Removal.

NEXT -- Continue to next step.

2. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

(a) Connect the Techstream to the DLC3.

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

(c) Clear the DTC Reading and Clearing Diagnostic Trouble Codes.

(d) Turn the engine switch off and wait for least 30 seconds or more.

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

(f) Start the engine and idle it for 10 seconds.

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

(h) Read the DTCs.
