PURGE FLOW MONITOR

The ECM detects whether the fuel vapor leakage
exists or not from the evaporative emission control
system. By the specified pattern within the certain
operation range, the ECM drives the evaporative
emission purge solenoid and the evaporative emis
-
sion ventilation solenoid. This allows slight vacuum
to be produced in the fuel tank.
The ECM measures the vacuum condition through
the fuel tank differential pressure sensor signal. By
comparing the normal (expected) value and the
actual value, the ECM detects whether the fuel vapor
leakage exists or not from the evaporative emission
control system.
