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.
1PERFORM SIMULATION TEST
(a)Clear the DTC (See page 05±5)
(b)Shuffle arrangement of the ighition coil and igniters.
NOTICE:
Do not shuffle the connectors.
(c)Perform the simulation test.

DTCP0340CAMSHAFT POSITION SENSOR CIRCUIT MALFUNCTION
CIRCUIT DESCRIPTION
The camshaft position sensor (G2 signal) consists of a magnet, iron core \
and pickup coil.
The G2 signal plate has 3 teeth on its outer circumference and is instal\
led on the camshaft timing pulley.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pickup coil changes,
causing fluctuations in the magnetic field and generating an electromoti\
ve force in the pickup coil.
The NE signal plate (crankshaft timing pulley) has 34 teeth and is instal\
led to the crankshaft. The NE signal
sensor generates 34 signals at every engine revolution. The ECM detects \
the crankshaft angle and the en-
gine revolution based on the NE signals, and the cylinder and the angle of the VVT based on the combination
of the G2 and NE signals.
