INSPECTION PROCEDURE
HINT:
Read freeze frame data usingthe hand−held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean or rich, and other data
from the time the malfunction occurred.

DTC P0443 EVAPORATIVE EMISSION CONTROL
SYSTEM PURGE CONTROL VALVE CIRCUIT
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 amount of HC emissions is ap-
propriate for the driving conditions (engine load, engine speed, vehicle speed, etc.) after the engine is
warmed up.

DTC P0335 CRANKSHAFT POSITION SENSOR ”A”
CIRCUIT
DTC P0339 CRANKSHAFT POSITION SENSOR ”A”
CIRCUIT INTERMITTENT
CIRCUIT DESCRIPTION
The crankshaft position sensor system consists of a crankshaft position sensor plate and a pick−up coil.
The sensor plate has 34 teeth and is installed on the crankshaft. The pick−up coil is made of an iron core
and magnet. The sensor plate rotates and as each tooth passes through the pick−up coil, a pulse signal is
created. The pick−up coil generates 34 signals for each engine revolution. Based on these signals, the ECM
calculates the crankshaft position and engine RPM. Using these calculations, the fuel injection time and igni-
tion timing are controlled.
