P0019
2GR-FE ENGINE CONTROL: 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
To monitor the correlation of the exhaust camshaft position and crankshaft position, the ECM checks the VVT learned value while the engine is idling. The VVT learned value is calibrated based on the camshaft position and crankshaft position. The exhaust valve timing is set to the most advanced angle while the engine is idling. If the VVT learned value is out of the specified range in consecutive driving cycles, the ECM illuminates the MIL and stores DTC P0017 (Bank 1) or P0019 (Bank 2).

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 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 NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE or UNKNOWN, 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 / Trouble Codes / Pending.
16. Read the pending DTCs [G].
HINT
- If a pending DTC is output, the system is malfunctioning.

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. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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 (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE)
(a) Connect the Techstream to the DLC3.
(b) Start the engine.
(c) Turn the Techstream on.
(d) Warm up the engine.
(e) Turn the A/C on.
(f) Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank 1) or Control the VVT Exhaust Linear (Bank 2).
(g) Check the engine speed while operating the camshaft timing oil control valve assembly using the Techstream.
OK:
NG -- CHECK VALVE TIMING (CHECK FOR LOOSE OR JUMPED TEETH ON TIMING CHAIN)
OK -- Continue to next step.
3. CHECK WHETHER DTC OUTPUT RECURS (DTC P0017 OR P0019)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Clear the DTCs DTC Check / Clear.
(e) Turn the engine switch off and wait for 30 seconds.

(g) Start the engine and warm it up.
(h) Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
(i) Enter the following menus: Powertrain / Engine / Utility / All Readiness.
(j) Input the DTC: P0017 or P0019.
(k) Check the DTC judgment result.
Result:

HINT
DTC P0017 or P0019 is output when foreign objects in engine oil are caught in some parts of the system. These codes will remain stored even if the system returns to normal after a short time. These foreign objects may then be captured by the oil filter, thus eliminating the source of the problem.
