Engine speed will not
rise more than 2,500 rpm
due to the fuel cut

Malfunction indicator
lamp circuit

When there is an open circuit on MI circuit, the ECM cannot warn the
driver by lighting up MI when there is malfunction on engine control
system.
Therefore, when electrical controlled throttle and part of ECM related
diagnoses are continuously detected as NG for 5 trips, ECM warns the
driver that engine control system malfunctions and MI circuit is open by
means of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MI
circuit are detected and demands the driver to repair the malfunction.

EC-314

DTC No.

Detected items

Engine operating condition in fail-safe mode

P0011

Intake valve timing control

The signal is not energized to the intake valve timing control solenoid valve and the valve
control does not function.

P0102
P0103

Mass air flow sensor circuit

Engine speed will not rise more than 2,400 rpm due to the fuel cut.

P0117
P0118

Engine coolant tempera-
ture sensor circuit

Engine coolant temperature will be determined by ECM based on the time after turning
ignition switch ON or START.
CONSULT-III displays the engine coolant temperature decided by ECM.

Condition

Engine coolant temperature decided

(CONSULT-III display)

Just as ignition switch is turned ON
or START

C (104

More than approx. 4 minutes after
ignition ON or START

C (176

Except as shown above

40 - 80

C (104 - 176

(Depends on the time)

When the fail-safe system for engine coolant temperature sensor is activated, the cooling
fan operates while engine is running.

Throttle position sensor

The ECM controls the electric throttle control actuator in regulating the throttle opening in
order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal
condition.
So, the acceleration will be poor.

P0605

ECM

(When ECM calculation function is malfunctioning:)
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
ECM deactivates ASCD operation.

P1121

Electric throttle control ac-
tuator

(When electric throttle control actuator does not function properly due to the return spring
malfunction:)
ECM controls the electric throttle actuator by regulating the throttle opening around the
idle position. The engine speed will not rise more than 2,000 rpm.

(When throttle valve opening angle in fail-safe mode is not in specified range:)
ECM controls the electric throttle control actuator by regulating the throttle opening to 20
degrees or less.

(When ECM detects the throttle valve is stuck open:)
While the vehicle is driving, it slows down gradually by fuel cut. After the vehicle stops, the
engine stalls.
The engine can restart in Neutral position, and engine speed will not exceed 1,000 rpm or
more.

P1122

Electric throttle control
function

ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.

P1124
P1126

Throttle control motor relay

ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.

*1: 1st trip DTC No. is the same as DTC No.

*2: This number is prescribed by 15031-5.

*3: In Diagnostic Test Mode II (Self-diagnostic results), this number is controlled by NISSAN.

*4: The troubleshooting for this DTC needs CONSULT-III.

*5: When the fail-safe operations for both self-diagnoses occur, the MI illuminates.

*6: SRT code will not be set if the self-diagnostic result is NG.

*7: When the ECM is in the mode of displaying SRT status, MI may flash. For the details, refer to “How to Display SRT Status”.

How to Set SRT Code

INFOID:0000000001056534

To set all SRT codes, self-diagnosis for the items indicated above must be performed one or more times. Each
diagnosis may require a long period of actual driving under various conditions.

WITH CONSULT-III

Perform corresponding DTC CONFIRMATION PROCEDURE one by one based on Performance Priority in
the table on “SRT Item”.

WITHOUT CONSULT-III

The most efficient driving pattern in which SRT codes can be properly set is explained on the next page. The
driving pattern should be performed one or more times to set all SRT codes.
