DTC P0340 Camshaft Position Sensor ºAº Circuit
(Bank 1 or Single Sensor)
DTC P0341 Camshaft Position Sensor ºAº Circuit
Range/Performance (Single Sensor)
CIRCUIT DESCRIPTION
The camshaft position sensor (G signal) consists of a magnet iron core and pickup coil.
The G signal plate has 1 tooth on its outer circumference and is installed on the LH camshaft timing pulley.
When the camshafts rotate, protrusion on the signal plate and air gap on the pickup coil change, causing
fluctuations in the magnetic field and generating a voltage in the pickup coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor generates 34
signals at every engine revolution. The ECM detects the crankshaft angle and the engine revolution based
on the NE signals, and the cylinder and the angle of the G2 based on the combination of the G and NE sig-
nals.

8. INSTALL CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being removed.
Otherwise, excessive pressure is put on the cylinder head
journal thrust, causing a burr on the journal and damage on
the camshaft. To avoid this, follow the steps below.
(a) Set the crankshaft pulley position.
Turn the crankshaft pulley clockwise or counterclockwise,
and put the timing mark of the crankshaft pulley in line with
the centers of the crankshaft pulley bolt and the idler
pulley bolt.
NOTICE:
Having the crankshaft pulley at the wrong angle can cause
the piston head and the valve head to come into contact
with each other when removing the camshaft, causing
damage on them. So always set the crankshaft pulley at the
correct angle.
(b) Install the RH camshafts.
(1) Apply MP grease to the thrust portion of the intake
and exhaust camshafts.
(2) Place the intake and exhaust camshafts.
(3) Set the timing mark (1 dot mark) of the camshaft
main gear at approx. 10° angle.
(4) Remove any old packing (FIPG) material from the
front bearing cap.
(5) Apply seal packing to the front bearing cap as
shown in the illustration.
Seal packing:
Part No. 08826-00080 or equivalent
Install a nozzle that is cut to a 1.5 mm (0.06
in.) opening.
Parts must be assembled within 5 minutes
the seal packing application. Otherwise the
material must be removed and the packing
have to be reapplied.
Immediately remove nozzle from the tube
and reinstall cap.
NOTICE:
Do not apply seal packing to the front bearing cap grooves.

(a) Check the crankshaft pulley position.
Check that the timing mark of the crankshaft pulley is
aligned with the centers of the crankshaft pulley bolt and
the idler pulley bolt.
NOTICE:
Having the crankshaft pulley at the wrong angle can cause
the piston head and the valve head to come into contact
with each other when removing the camshaft, causing
damage on them. So always set the crankshaft pulley at the
correct angle.
(b) Remove the RH camshafts.
(1) Move a service bolt of the sub-gear upward by turn-
ing the hexagon shaped port of the exhaust cam-
shaft with a wrench.
(2) Secure the sub-gear to the main gear with a service
bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 - 20 mm
HINT:
When removing the camshafts, make sure that the torsional
spring force of the sub-gear is eliminated by the above opera-
tion.
(3) Set the timing mark (1 dot mark) of the camshaft
main gear at approx. 10° angle by turning the hexa-
gon wrench head portion of the exhaust camshaft
with a wrench.
(4) Uniformly loosen and remove the 22 bearing cap
bolts a little at a time for several times in the se-
quence shown.
(5) Remove the oil feed pipe, 9 bearing caps, cam shaft
timing oil control valve and camshafts.
