DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory
P0016	Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)	Deviation in the crankshaft position sensor signal and VVT sensor (for intake side of bank 1) signal (2 trip detection logic).	Valve timing Camshaft timing intake gear assembly LH (bank 1) ECM	Comes on (Euro-OBD) / Does not come on (Except Euro-OBD)	DTC stored
P0018	Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor A)	Deviation in the crankshaft position sensor signal and VVT sensor (for intake side of bank 2) signal (2 trip detection logic).	Valve timing Camshaft timing intake gear assembly RH (bank 2) ECM	Comes on (Euro-OBD) / Does not come on (Except Euro-OBD)	DTC stored

MONITOR DESCRIPTION

These DTCs are stored when a deviation in the valve timing is detected. If a deviation in the valve timing is detected when the engine is idling (during valve timing learning) after performing learning value reset using the GTS or when the vehicle is being driven, the ECM determines that a malfunction has occurred. If a deviation in the valve timing is detected in consecutive driving cycles, the ECM illuminates the MIL and stores a DTC.

If the valve timing has deviated, the camshaft position sensor malfunction DTC P1340 may be stored.

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.

DTC P0016 and/or P0018 may be output if the battery is reconnected and the engine is started while the following are disconnected from the camshaft timing control motor with EDU assembly: 1) power source harness or connector; or 2) ECM harness or connector.

If P0016 and/or P0018 is output, check if the harness or connector is disconnected.

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS 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).
Turn the GTS 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 [D].
Read the pending DTCs.
Tech Tips
- 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: P0016 or P0018.

Check the DTC judgment result.

GTS 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
N/A	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

Tech Tips

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 N/A, 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].
Enter the following menus: Powertrain / Engine / Trouble Codes [G].
Read the pending DTCs.
Tech Tips
- 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.
Tech Tips
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has malfunction.
- If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT

CAUTION:

After turning engine switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.

Tech Tips

The GTS only:

By using the Control the VVT-iE Linear (Bank 1) or Control the VVT-iE Linear (Bank 2) Active Test, it can be determined if the VVT-iE system is malfunctioning.

Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Start the engine and warm it up.
Enter the following menus: Powertrain / Engine / Active Test / Control the VVT-iE Linear (Bank 1) or Control the VVT-iE Linear (Bank 2).
Monitor VVT Target Angle #1 and VVT Change Angle #1 or VVT Target Angle #2 and VVT Change Angle #2.

Perform the Active Test operation with the engine speed at 1500 rpm.

OK:
Active Test Movement Order	Difference between "VVT Target Angle" and "VVT Change Angle"
0 deg → 10 deg → 20 deg → 40 deg → 10 deg → 0 deg → 10 deg → END	Within 5 DegFR

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.
Read freeze frame data using the GTS. 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

CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016 OR P0018)

Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.

Powertrain > Engine > Trouble Codes

Read the DTCs.

Tech Tips

If any DTCs other than P0016 or P0018 are output, troubleshoot those DTCs first.

Turn the crankshaft pulley, and align its groove with the timing mark "0" of the timing chain cover.

Check that the timing marks of the camshaft timing intake gear assemblies and camshaft timing exhaust gear assemblies are at the positions shown in the illustration.

OK
The timing marks on the camshaft timing gears are aligned as shown in the illustration.

Tech Tips

If the result is not as specified, check for mechanical malfunctions that may have affected the valve timing, such as a jumped tooth or stretching of the timing chain.
When checking the valve timing, make sure the camshaft timing intake gear assemblies are set to the most retarded position and the camshaft timing exhaust gear assemblies are set to the most advanced position. When the VVT system is normal and the engine is stopped, the camshaft timing intake gear assemblies stop at the center of their operation range and the camshaft timing exhaust gear assemblies stop at the most advanced position.
