M20F-FXS, M20G-FXS ENGINE CONTROL SFI SYSTEM P001600 Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A
DESCRIPTION
Refer to DTC P001001.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | 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) signal (2 trip detection logic). | ·

Comes on / Does not come on | SAE Code: P0016 |
- HINT:
-
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 may be stored. If DTC P001600 is output, check the connection condition of each connector.
MONITOR DESCRIPTION
This DTC is 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
- HINT:
- ·
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
·When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON [A].
Turn the GTS on.
Put the engine in Inspection Mode (Maintenance Mode).
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: P001600.
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 |
- 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 auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
With the engine running, drive the vehicle for 10 minutes or more [E].
- CAUTION:
-
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
- HINT:
-
If the engine stops, further depress the accelerator pedal to restart the engine.
Idle the engine for 5 minutes or more [F].
Enter the following menus: Powertrain / Engine / Trouble Codes [G].
Read the pending DTCs.

·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 auxiliary 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
- NOTICE:
- ·
Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the Freeze Frame Data and Vehicle Control History can be useful for troubleshooting.
(Select Powertrain in Health Check and then check the time stamp data.)
·If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.
- HINT:
-
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.

Remove the cam timing control motor with EDU assembly.
Check if the eccentric shaft of the camshaft timing gear assembly rotates smoothly.
- NOTICE:
-
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.
