M20F-FXS, M20G-FXS ENGINE CONTROL SFI SYSTEM P001100 Camshaft Position "A" - Timing Over-Advanced or System Performance Bank 1
DESCRIPTION
Refer to DTC P001001.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Note |
|---|---|---|---|---|---|
| P001100 | Camshaft Position "A" - Timing Over-Advanced or System Performance Bank 1 | With engine warmed up and while driving in urban area (engine speed 4000 rpm or less), intake side valve timing does not change in advanced position, and target and actual valve timing do not match (1 trip detection logic). | ·
Camshaft timing gear assembly ·
ECM |
Comes on | SAE Code: P0011 |
MONITOR DESCRIPTION
This DTC is output when a valve timing stuck condition is detected. With the engine speed at 4000 rpm or less in the advance angle position, if the valve timing does not vary, and there is a large difference in the target and actual valve timing, it is determined that a malfunction has occurred. When this malfunction is detected, the ECM will illuminate the MIL and store this 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).
- HINT:
-
Clear the DTC without using the GTS.
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].
With the engine running, drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more [C].
- 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 3 minutes or more [D].
Enter the following menus: Powertrain / Engine / Trouble Codes [E].
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: P001100.
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 [F] through [H].
·[A] to [E]: 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, repeat the pattern of accelerating the vehicle from rest to approximately 60 km/h (37 mph) and then decelerating the vehicle 10 to 15 times [F].
- 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.
·Depress the accelerator pedal by a large amount.
Idle the engine for 3 minutes or more [G].
Enter the following menus: Powertrain / Engine / Trouble Codes [H].
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 again.
- HINT:
- ·
If the judgment result is NORMAL, the system is normal.
·If the judgment result is ABNORMAL, the system has a malfunction.
·[A] to [H]: 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.

The GTS only:
By using the Control the VVT-iE Opening Angle Bank 1 Active Test, it can be determined if the VVT-iE system is malfunctioning.
(a)Connect the GTS to the DLC3.
(b)Turn the ignition switch to ON.
(c)Turn the GTS on.
(d)Clear the DTCs.
- HINT:
-
Clear the DTC without using the GTS.
(e)Turn the ignition switch off and wait for at least 30 seconds.
(f)Turn the ignition switch to ON.
(g)Turn the GTS on.
(h)Put the engine in Inspection Mode (Maintenance Mode).
(i)Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher.
(j)Enter the following menus: Powertrain / Engine / Active Test / Control the VVT-iE Opening Angle Bank 1 / Data List / Intake VVT Change Angle Bank 1 and Intake VVT Target Angle Bank 1.
(k)Read the Data List while performing the Active Test with the engine idling.
OK: Active Test Movement Order Difference between "Intake VVT Change Angle Bank 1" and "Intake VVT Target Angle Bank 1" 0 deg → 10 deg → 20 deg → 40 deg → 0 deg → 10 deg → END Within 4 DegFR
·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.
