P2614

1UR-FSE ENGINE CONTROL SYSTEM: SFI SYSTEM: P1023,P2614: Camshaft Position Signal Output "B" Circuit
P2614 - Camshaft Position Signal Output Circuit / Open

DESCRIPTION

Refer to DTC P0010 P0010.





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 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) DTC Check / Clear.

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 [A].

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

8. Read the DTCs [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: P1023 or P2614.

11. Check the DTC judgment result.





12. If the test result is INCOMPLETE or UNKNOWN and no DTC is output, perform a universal trip and check for permanent DTCs DTC Check / Clear.

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.

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) Start the engine and idle it for 10 seconds.

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

(d) Read the DTCs.
