P001600, P001800

DTC Code	DTC Name
P001600	Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A
P001800	Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor A

DESCRIPTION

Refer to DTC P001001.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory	Note
P001600	Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A	Deviation in the crankshaft position sensor signal and camshaft position sensor (for intake camshaft of bank 1) signal (2 trip detection logic).	Valve timing Camshaft timing intake gear assembly (bank 1) ECM	Comes on/-	DTC stored	SAE: P0016
P001800	Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor A	Deviation in the crankshaft position sensor signal and camshaft position sensor (for intake camshaft of bank 2) signal (2 trip detection logic).	Valve timing Camshaft timing intake gear assembly (bank 2) ECM	Comes on/-	DTC stored	SAE: P0018

Tech Tips

If initialization is performed using the GTS with any of the connectors of the wire harnesses between the power source or ECM and the cam timing control motor with EDU assembly disconnected, DTC P001600 and/or P001800 may be stored. If DTC P001600 and/or P001800 is output, check the connection condition of each connector.

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 will illuminate the MIL and store a DTC.

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) [A].
Turn the GTS 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.
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: P001600 or P001800.

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

Tech Tips

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].

Drive the vehicle for 10 minutes or more [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 is NORMAL, the system is normal.
- If the judgment result is ABNORMAL, the system has a malfunction.

CAUTION / NOTICE / HINT

Tech Tips

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.
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.

DTC	Suspected Area
P001600	Bank 1
P001800	Bank 2

PROCEDURE

CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P001600 OR P001800)

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

Read the DTCs.

Powertrain > Engine > Trouble Codes

*2	Eccentric Shaft
*a	Spline

Remove the cam timing control motor with EDU assembly.

for bank 1: Click here

for bank 2: Click here

Check if the eccentric shaft of the camshaft timing intake gear assembly rotates smoothly.

Note

If the camshaft is at a position where a valve is about to open, the eccentric shaft may become difficult to rotate.

OK
Rotates smoothly.
