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) Reading and Clearing Diagnostic Trouble Codes.

4. Turn the engine switch off and wait for 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 engine coolant temperature 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 DTC [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 N/A, perform steps [E] through [G].

13. Drive the vehicle for 2 to 3 minutes [E]

CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.

14. Idle the engine for 5 minutes or more [F]

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

16. Input the DTC: P0017 or P0019.

17. Check the DTC judgment result [G].

HINT
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows NORMAL, the system is normal.

18. 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
- 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.
- 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.

PROCEDURE

1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0017 OR P0019)

(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





HINT
If any DTCs other than P0017 or P0019 are output, troubleshoot those DTCs first.

B -- GO TO DTC CHART SFI System
A -- Continue to next step.

2. 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 assumed that the VVT system is operating normally.

(a) Connect the Techstream to the DLC3.

(b) Start the engine.

(c) Turn the Techstream on.

(d) Warm up the engine.

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

(f) Perform the Active Test. Check that the displacement angle varies.

OK:

Displacement angle varies.

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

3. ADJUST VALVE TIMING P0016

NEXT -- CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

4. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY P0014

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

5. INSPECT OIL CONTROL VALVE FILTER

(a) Remove the cylinder head cover sub-assembly Disassembly.

(b) Remove the OCV filter Disassembly.

(c) Inspect the OCV filter.

OK:

Filter is not clogged.

NG -- CLEAN OR REPLACE OIL CONTROL VALVE FILTER
OK -- Continue to next step.

6. REPLACE CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY

(a) Replace the camshaft timing exhaust gear assembly Disassembly.

NEXT -- Continue to next step.

7. 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) Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.

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

(g) Read the DTCs.

Result:





B -- REPLACE ECM Removal

A -- END
