DTC P0340 Camshaft Position Sensor Circuit
Malfunction
CIRCUIT DESCRIPTION
Camshaft position sensor (G signal) consist of signal plate and pickup coil.
The G signal plate has one tooth on its outer circumference and is mounted on the exhaust camshaft.
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 an electromotive force in the pickup coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor generates 34
signals for every engine revolution. The ECM detects the standard crankshaft angle based on the G signals
and the actual crankshaft angle and the engine speed by the NE signals.

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. REMOVE SPARK PLUGS (See page IG-1)
3. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain engine revolutions
of 250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible.
Compression pressure:
1,275 kPa (13.0 kgf/cm
2, 185 psi) or more
Minimum pressure:
980 kPa (10.0 kgf/cm
2, 142 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 14 psi) or less
(e) If the cylinder compression in one or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (c) for
cylinders with low compression.

If adding oil helps the compression, chances are
that the piston rings and/or cylinder bore are worn
or damage.

If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
4. REINSTALL SPARK PLUGS

VALVE CLEARANCE
INSPECTION
HINT:
Inspect and adjust the valve clearance when the engine is cold.
1. DISCONNECT PCV HOSES FROM CYLINDER HEAD
COVER
2. REMOVE HIGH- TENSION CORDS AND IGNITION
COILS FROM SPARK PLUGS
3. REMOVE CYLINDER HEAD COVER
(a) Remove the oil filler cap.
(b) Remove the 5 cap nuts and seal washers.
(c) Pry out the cylinder head cover, and remove the cover
and gasket.
4. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its groove with the
timing mark º0º of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 cylinder are loose
and valve lifters on the No.4 cylinder are tight.
If not, turn the crankshaft 1 complete revolution (360°) and align
the marks as above.
5. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and camshaft.
(2) Record the out-of-specification valve clearance
measurements. They will be used later to determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake0.15 - 0.25 mm (0.006 - 0.010 in.)
Exhaust0.31 - 0.41 mm (0.012 - 0.016 in.)
