P1065 nissan murano z50

Nissan Murano Z50 (2003 year). Manual — part 106

NOTE:
If DTC P0507 is displayed with other DTC, first perform the trouble diagnosis for the other DTC.
The ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let
into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is
varied to allow for optimum control of the engine idling speed. The crankshaft position sensor (POS) detects
the actual engine speed and sends a signal to the ECM.
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value
memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily.
The optimum value stored in the ECM is determined by taking into consideration various engine conditions,
such as during warming up, deceleration, and engine load (air conditioner, power steering and cooling fan
operation, etc.).

On Board Diagnosis Logic

DTC Confirmation Procedure

If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and
wait at least 10 seconds before conducting the next test.

If the target idle speed is out of the specified value, perform “Idle Air Volume Learning”,

before conducting “DTC Confirmation Procedure”. For the target idle speed, refer to the “Service
Data and Specifications (SDS)”,

Before performing the following procedure, confirm that battery voltage is more than 11V at idle.

Always perform the test at a temperature above

Start engine and warm it up to normal operating temperature.

Turn ignition switch “OFF” and wait at least 10 seconds.

Turn ignition switch “ON” again and select “DATA MONITOR”
mode with CONSULT-II.

Start engine and run it for at least 1 minute at idle speed.

If 1st trip DTC is detected, go to

Follow the procedure “WITH CONSULT-II” above.

Idle speed control sys-
tem RPM higher than
expected

The idle speed is more than the target idle
speed by 200 rpm or more.

Проблема зачастую кроется намного глубже чем кажется на первый взгляд. Это& вызвано теми обстоятельствами, что информационные сообщения содержат, как было выше сказано, косвенную информацию о нарушении работы системы.

Может быть полезным для решения вопроса по устранению неисправности у Nissan Murano (Z50):

Возможные причины: Неисправный модуль управления двигателем (ECM); Цепь питания жгута проводов модуля управления двигателем (ECM) разомкнута или замкнута; Цепь заземления жгута проводов модуля управления двигателем (ECM) разомкнута или замкнута.

Резервная система с произвольным доступом к памяти (RAM) модуля управления двигателем (ECM) не работает должным образом.
Напряжение аккумуляторной батареи подается на модуль управления двигателем ( ECM ), даже когда ключ зажигания выключен для функции памяти ECM памяти DTC, памяти значений компенсации обратной связи соотношения воздух-топливо, памяти значений запоминающего устройства объема холостого хода и т. Д.

Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM’s transistor. Use a ground other than ECM terminals, such as the ground.

DTC P1111, P1136 IVT CONTROL SOLENOID VALVE

Component Description

Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.
