P0019

1UR-FSE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0017,P0019: Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor B)
P0019 - Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor B)

DESCRIPTION

Refer to DTC P0013 P0013.





MONITOR DESCRIPTION

These DTCs are output when a valve timing deviation condition is detected. While the vehicle is being driven or the engine is idling (after the battery terminals are reconnected), if a valve timing deviation is detected during the valve timing initialization operation, it is determined that a malfunction has occurred. If this condition is detected while driving, a DTC is output (2 trip detection logic). However, if the valve timing is deviated, the camshaft position sensor malfunction DTC P1340 may be output.

A DTC is output if the following occurs: 1) the engine is idled, and then the engine switch is turned off; and 2) the engine is started and the engine is idled.

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 [A].

6. Start the engine and warm it up until the ECT reaches 75°C (167°F) or higher [B].

7. Idle the engine for 5 minutes or more [C].

8. Enter the following menus: Powertrain / Engine / Trouble Codes / Pending.

9. Read the pending DTCs [D].

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

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

11. Input the DTC: P0017 or P0019.

12. 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 shows INCOMPLETE or UNKNOWN, perform steps [E] through [G].

13. Idle the engine for 5 minutes or more [E].

14. Turn the engine switch off [F].

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

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

17. Input the DTC: P0017 or P0019.

18. Check the DTC judgment result [H].

19. If the test result is INCOMPLETE or UNKNOWN and no pending 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. PERFORM ACTIVE TEST USING TECHSTREAM (CONTROL THE VVT EXHAUST LINEAR)

HINT
If the VVT system can be operated through the Active Test, it can be determined that there is no problem in the VVT system.

(a) Connect the Techstream to the DLC3.

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

(c) Start the engine and warm it up.

(d) Engine is idling.

(e) Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank 1) or Control the VVT Exhaust Linear (Bank 2).

(f) Check the engine speed while operating the Oil Control Valve (OCV) using the Techstream.

OK:





NG -- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE
OK -- Continue to next step.

2. ADJUST VALVE TIMING P0016

NEXT -- CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

3. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE P0014

NG -- REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY Removal
OK -- Continue to next step.

4. REPLACE CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY

(a) Replace the camshaft timing exhaust gear assembly [1][2]Disassembly.

NEXT -- Continue to next step.

5. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

(a) To initialize the ECM's valve timing, disconnect the cable from the negative (-) battery terminal for 1 minute.

(b) Connect the cable to the negative (-) battery terminal Service Precautions.

(c) Connect the Techstream to the DLC3.

(d) Switch the ECM from normal mode to check mode using the Techstream Check Mode Procedure.

(e) Start the engine and idle it for 5 minutes.

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

(g) Read the DTCs.
