NOTE:
If DTC P0441 is displayed with P0121, P0122, P0123, P0226, P0227, P0228, P1227 or P1228, perform
trouble diagnosis for other DTC.
SEC936C
In this evaporative emission (EVAP) control system, purge flow occurs during non-closed throttle conditions.
Purge volume is related to air intake volume. Under normal purge conditions (non-closed throttle), the EVAP
canister purge volume control solenoid valve is open to admit purge flow. Purge flow exposes the EVAP con-
trol system pressure sensor to intake manifold vacuum.
On Board Diagnosis Logic
NFEC0956
Under normal conditions (non-closed throttle), sensor output volt-
age indicates if pressure drop and purge flow are adequate. If not,
a fault is determined.
DTC No.
