2GR-FKS (ENGINE CONTROL): SFI SYSTEM: P001700,P001900; Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor B; 2018 MY Camry [06/2017

In the VVT (Variable Valve Timing) system, the appropriate exhaust valve open and close timing is controlled by the ECM. The ECM performs exhaust valve control by performing the following: 1) controlling the exhaust camshaft cam timing oil control solenoid assembly, camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) and operating the camshaft timing exhaust gear; and 2) changing the relative positions of the camshaft and crankshaft.

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 neutral position while the engine is idling. If the VVT learned value is out of the specified range in consecutive driving cycles, the ECM stores a DTC.

CONFIRMATION DRIVING PATTERN

Connect the Techstream to the DLC3.
Turn the engine switch on (IG).
Turn the Techstream on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the engine switch off and wait for at least 30 seconds.
Turn the engine switch on (IG) [A].
Turn the Techstream on.
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 [D].
Read the pending DTCs.
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: P001700 or P001900.

Check the DTC judgment result.

Techstream Display	Description
NORMAL	DTC judgment completed System normal
ABNORMAL	DTC judgment completed System abnormal
INCOMPLETE	DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions

HINT:

If the judgment result is NORMAL, the system is normal.
If the judgment result is ABNORMAL, the system has a malfunction.
If the judgment result is INCOMPLETE, perform steps [E] through [G].
[A] to [D]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

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].
Enter the following menus: Powertrain / Engine / Trouble Codes [G].
Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
Check the DTC judgment result.
HINT:
- If the judgment result is NORMAL, the system is normal.
- If the judgment result is ABNORMAL, the system has a malfunction.
- [A] to [G]: Normal judgment procedure.
  The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT

HINT:

Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from the transaxle.
Bank 2 refers to the bank that does not include the No. 1 cylinder.
The monitor for this DTC detects when the timing chain is shifted by one tooth or more (except for Mexico models).
The monitor for this DTC detects when the timing chain is shifted by 2 to 3 teeth or more (for Mexico models).
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.

PROCEDURE

Powertrain > Engine > Trouble Codes

If the VVT system can be operated through the Active Test, it can be assumed that the VVT system is operating normally.

(d) Enter the following menus: Powertrain / Engine / Active Test / Control the Exhaust VVT OCV Duty Ratio Bank 1 or Control the Exhaust VVT OCV Duty Ratio Bank 2 / Data List / Exhaust VVT Change Angle Bank 1 or Exhaust VVT Change Angle Bank 2.

Powertrain > Engine > Active Test

(a) Check for mechanical malfunctions that affect the valve timing, such as a jumped tooth or stretching of the timing chain.

Perform "Inspection After Repair" after repairing or replacing the engine mechanical system.

(a) Inspect the cam timing oil control solenoid assembly (for exhaust camshaft).

(a) Inspect the camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]).

(a) Remove the oil control valve filter (for exhaust camshaft of bank 1) or oil control valve filter (for exhaust camshaft of bank 2).

Powertrain > Engine > Clear DTCs

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

Powertrain > Engine > Trouble Codes

Perform "Inspection After Repair" after replacing the camshaft timing exhaust gear assembly.

Powertrain > Engine > Clear DTCs

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