when a malfunction is detected. When troubleshooting, it is useful for deter\
mining whether the vehicle

DTCP0341/12CAMSHAFT POSITION SENSOR ºAº CIRCUIT RANGE/PERFORMANCE (BANK 1

CIRCUIT DESCRIPTION
The camshaft position sensor (G signal) consists of a magnet, iron core a\
nd pickup coil.
The G signal rotor has 3 teeth on its outer circumference and is install\
ed on the intake camshaft.
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 position sensor plate) has 34 teeth an\
d is installed to the crankshaft. The
NE signal sensor generates 34 signals at every engine revolution. The EC\
M detects the crankshaft angle
and the engine revolution based on the NE signals, and the cylinder and the\
angle of the VVT based on the
combination of the G and NE signals.

CIRCUIT DESCRIPTION
The camshaft position sensor (G2 signal) consists of a magnet, iron core and pickup coil.
The G2 signal rotor has 3 teeth on the outside and is mounted on the intake camshaft.

causing fluctuations in the magnetic field and generating an electromotive force in the pickup coil.
The NE signal plate (crankshaft position sensor plate No. 1) has 34 teeth and is installed on the crankshaft.

DTC P0340 CAMSHAFT POSITION SENSOR ”A” CIRCUIT (BANK1 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 installed on the camshaft timing pulley.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pickup coil change,
causing fluctuations in the magnetic field and generating voltage in the pickup coil.
The ECM detects each cylinder position based on a combination of the G signal and a signal from the crank-
shaft position sensor (NE signal).

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the 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.

ON−VEHICLE INSPECTION
1. CHECK ENGINE OIL LEVEL
(a) Warm up the engine. Stop the engine, then wait for 5 minutes.
(b) Check that the engine oil level is between the 2 marks on the oil level gage.
If low, check for leakage and add oil up to the upper mark.
NOTICE:
Do not fill with engine oil above the upper mark.
2. CHECK ENGINE OIL QUALITY
(a) Check the oil for deterioration, water intrusion, discoloring
or thinning.
If the quality is visibly poor, replace the oil.
Oil grade:
Use ACEA B1, API grade CF−4, CF or G−DLD−1.
(You may also use API CE or CD.)
SAE 5W−30 is the best choice for your vehicle in
terms of good fuel economy and good starting in cold
weather.
3. REMOVE OIL PRESSURE SWITCH ASSY
(a) Disconnect the oil pressure switch connector.
(b) Using a deep socket wrench 24mm, remove the oil pres-
sure switch.
4. INSTALL OIL PRESSURE GAUGE
(a) Install the oil pressure gauge.
5. WARM UP ENGINE
6. CHECK OIL PRESSURE
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.3 psi) or more
At 4,500 rpm245 to 588 kPa (2.5 to 6.0 kgf/cm2, 36 to 85 psi) or more

AVENSIS Supplement (RM1045E)
9. INSPECT COMPRESSOR OIL
(a) When replacing the w/pulley compressor assy with a new one, after gradually removing the refrigerant
gas from the service valve, drain the following amount of oil from the new w/pulley compressor assy
before installation.
Standard:
(Oil capacity inside new w/pulley compressor assy: 90 + 15 cc (3.0 + 0.5 fl. oz.) ) − (Remaining
oil amount in the removed w/pulley compressor assy) = (Oil amount to be removed when replac-
ing)
NOTICE:
S When checking the compressor oil level, observe the precautions on the cooler removal/instal-
lation.
S Since compressor oil remains in the pipes of the vehicle, if a new w/pulley compressor assy
is installed without removing some oil inside, the oil amount becomes excessive, preventing
heat exchange in the refrigerant cycle and causing refrigerant failure.
S If the remaining oil in the removed w/pulley compressor assy is too small in volume, check for
oil leakage.
S Be sure to use ND −OIL 8 for compressor oil.
10. INSTALL W/PULLEY COMPRESSOR ASSY
(a) Install the w/pulley compressor assy with the 4 bolts.
Torque: 29 N
m (300 kgf
cm, 2 1 ft
lbf)
NOTICE:
Tighten the bolts in the order shown in the illustration to
install the w/pulley compressor assy.
(b) Connect the connector.
11 . INSTALL FAN AND GENERATOR V BELT (See page 14− 5)
SST 09249 −63010
12. INSTALL COOLER REFRIGERANT DISCHARGE
HOSE NO. 1
(a) Remove the attached vinyl tape from the hose.
(b) Sufficiently apply compressor oil to a new O −ring and the
fitting surface of the w/pulley compressor assy.
Compressor oil: ND −OIL 8 or equivalent
(c) Install the O −ring on the cooler refrigerant discharge hose
