P0019

4GR-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

The ECM checks valve timing (VVT learning value) on the exhaust side while the engine is running at a low speed, in order to monitor the gap between current and target valve timings on the exhaust side. The VVT learning value is calculated from the positions of the camshaft and crankshaft. The camshaft will come to the most retarded position when the engine is running at a low speed. If the camshaft position is normal, the VVT learning value should be within the specified range. If the VVT learning value is not within the specified range, the ECM determines this as a malfunction.

CONFIRMATION DRIVING PATTERN





- Connect the Techstream to the DLC3.

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

- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) DTC Check / Clear.

- Turn the engine switch off and wait for 30 seconds.

- Turn the engine switch on (IG) and turn the Techstream on [A].

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

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

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

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

- Input the DTC: P0017 or P0019.

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

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

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

- 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.
- 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 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 Freeze Frame Data.

PROCEDURE

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

(a) Connect Techstream to the DLC3.

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

(c) Select the following menu items: Powertrain / Engine / Trouble Code.

(d) Read the DTCs.

Result:





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

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

2. PERFORM ACTIVE TEST USING TECHSTREAM (OPERATE OIL CONTROL VALVE FOR EXHAUST CAMSHAFT)

(a) Connect Techstream to the DLC3.

(b) Start the engine and turn the tester on.

(c) Warm up the engine.

(d) Select the following menu items: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank 1) or Control the VVT Exhaust Linear (Bank 2).

(e) Check the engine speed while operating the oil control valve using the tester.

OK:





NG -- CHECK VALVE TIMING (CHECK FOR LOOSE AND JUMP 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.

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

(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) Select the following menu items: Powertrain / Engine / Utility / All Readiness.

(j) Input the DTC: P0017 or P0019.

(k) Check the DTC judgment result.

Result:





HINT
DTC P0017 or P0019 may be stored when foreign objects in the engine oil are caught in some parts of the system. The DTC will remain set even if the system returns to normal after a short time. Those foreign objects may then be captured by the oil filter.

B -- CHECK VALVE TIMING (CHECK FOR LOOSE AND JUMP TEETH ON TIMING CHAIN)

A -- CHECK FOR INTERMITTENT PROBLEMS

4. CHECK VALVE TIMING (CHECK FOR LOOSE AND JUMP TEETH ON TIMING CHAIN)

(a) Remove the cylinder head covers RH and LH.





(b) Turn the crankshaft to align the matchmarks of the crankshaft.

(c) Align the notch of the crankshaft pulley to the "0" position.

(d) Check if the matchmarks of the camshaft pulley and camshaft bearing cap align.

(e) Turn the crankshaft clockwise by 360° if the matchmarks do not align. Check if they align once again.

OK:

The matchmarks of the camshaft pulley and the camshaft bearing cap align when the notch of the crankshaft pulley is in the "0" position.

(f) Reinstall the cylinder head cover RH and LH.

NG -- ADJUST VALVE TIMING
OK -- Continue to next step.

5. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR EXHAUST CAMSHAFT)
