INSPECTION PROCEDURE
HINT:
Read freeze frame data using \b
 . 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, etc. at the time of the malfu\
nction.
1CHECK OPERATION OF SPEEDOMETER
(a)Drive the vehicle and check if the operation of the speedometer in the combination meter is normal.
HINT:
The vehicle speed sensor is operating normally if the speedometer displa\
y is normal.

AVENSIS REPAIR MANUAL (RM1018E)
MONITOR DESCRIPTION
This DTC will be set if the actual opening angle of the intake shutter valve varies from the target opening
angle. The ECM forces the valve to fully open within 2 to 3 seconds as the ignition switch is turned ON, and
then checks if the intake shutter valve fully opened switch is turned on. In addition, the ECM also forces the
valve to fully open when accelerating the engine (high engine load) and checks if the switch is turned ON.
When starting and/or accelerating the engine, the ECM sets this DTC if the switch is not turned on.
If the DTC is present, the ECM enters fail±safe mode and limits the engine power. The fail±safe mode will
continue until the ignition switch is turned OFF.

ECM
MONITOR DESCRIPTION
When starting a cold engine, the ECM supplies the current to the glow plug for a certain period of time. As
the supplying current to the glow plug is terminated, the large current is suddenly cut off, therefore the battery
voltage then varies and also terminal M output (duty ratio) of the generator varies. If these variations are not
occurred when the glow plug is turned from ON to OFF, or vice±versa, the ECM realizes that the current has
not been supplied to the glow plug, and interprets this as open malfunction of the glow plug or glow plug
circuit.

DTCP0340CAMSHAFT POSITION SENSOR ºAº CIRCUIT (BANK 1 OR SINGLE SENSOR)
CIRCUIT DESCRIPTION
Camshaft position sensor (G signal) consists of a magnet, iron core and pickup\
coil.
The G signal plate has one tooth on its outer circumference and is installe\
d on the camshaft timing pulley.
When the camshafts rotate, the protrusion on the signal plate and the air ga\
p on the pickup coil change,
causing fluctuations in the magnetic field and generating an electromoti\
ve force in the pickup coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft timing pu\
lley. The NE signal sensor gen-
erates 34 signals at every engine revolution. The ECM detects the standard crankshaft angl\
e based on the
G signal and the actual crankshaft angle and the engine speed by the NE s\
ignal.
