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.

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.
1INSPECT CAMSHAFT POSITION SENSOR
(a)Measure the resistance between terminals 1 and 2. Resistance:
1,630 to 2,740 at cold

ECM POWER SOURCE CIRCUIT
CIRCUIT DESCRIPTION
When the ignition switch is turned ON, battery positive voltage is applied to terminal IGSW of the ECM and
the EFI MAIN relay (Marked: EFI MAIN) control circuit in the ECM sends a signal to terminal MREL of the
ECM switching on the EFI MAIN relay.
This signal causes current to flow to the coil, closing the contacts of the EFI MAIN relay and supplying power
to terminal +B of the ECM.
If the ignition switch is turned off, the ECM continues to switch on the EFI MAIN relay for a maximum of 2
seconds for the initial setting of the throttle valve.

DTC C0205/32 LEFT FRONT SPEED SENSOR
DTC C1330/35 RIGHT FRONT SPEED SENSOR CIRCUIT
DTC C1331/36 LEFT FRONT SPEED SENSOR CIRCUIT
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and transmits the ap-
propriate signals to the ECU. These signals are used for control
of the ABS control system. Each of the front and rear rotors has
48 serrations.
When the rotors rotate, the magnetic field generated by the per-
manent magnet in the speed sensor induces an AC voltage.
Since the frequency of this AC voltage changes in direct propor-
tion to the speed of the rotor, the frequency is used by the ECU
to detect the speed of each wheel.
