DTC P0443 EVAPORATIVE EMISSION CONTROL SYSTEM PURGE CONTROL VALVE CIRCUIT
MALFUNCTION
CIRCUIT DESCRIPTION
To reduce HC emissions, evaporated fuel from the fuel tank is routed through the charcoal canister to the
intake manifold for combustion in the cylinders.
The ECM changes the duty signal to the VSV for EVAP so that the intake quantity of HC emissions becomse
properly for the driving conditions (engine load, engine speed, vehicle speed, \
etc.) after the engine is
warmed up.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using \f  \b \f\f
 Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.

NSPECTION PROCEDURE
HINT:
This diagnostic chart is on the premise that the engine is cranked normally. If the engine is not cranked,
pro-

ceed to the problem symptoms table on page 05±22.
1 READ VALUE OF HAND±HELD TESTER(STARTER SIGNAL)
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand±held tester main switch \
ON.
(c) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL / STARTER SIGº and read its value dis-
played on the hand±held tester.
