SEF340V
SEF954S
Component Description
NGEC0264
The EVAP control system pressure sensor detects pressure in the
purge line. The sensor output voltage to the ECM increases as
pressure increases. The EVAP control system pressure sensor is
not used to control the engine system. It is used only for on board
diagnosis.
CONSULT-II Reference Value in Data Monitor
Mode
NGEC0265
Specification data are reference values.
MONITOR ITEM CONDITION SPECIFICATION
EVAP SYS PRES 쐌 Ignition switch: ON Approx. 3.4V
ECM Terminals and Reference Value
NGEC0266
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
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.
