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, 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.

(a)Connect the hand±held tester to the DLC3.
(b)Start the engine and warm it up.
(c)Turn the ignition switch ON and push the hand±held tester main switch \
ON.
(d)Select the item ºDIAGNOSIS / OBD/MOBD / ACTIVE TEST / VVT CTRL B1º\
.
(e)Check the engine speed when operating the OCV by the hand±held tester.

CIRCUIT
DTC P0339 CRANKSHAFT POSITION SENSOR ºAº
CIRCUIT INTERMITTENT
CIRCUIT DESCRIPTION
The crankshaft position sensor (NE signal) consists of a magnet, iron core and pick up coil.
The NE signal plate (crankshaft position sensor plate No. 1) has 34 teeth and is installed 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 signal, and the cylinder and the angle of the VVT based
on the combination of the G2 and NE signal.
DTC No.DTC Detection ConditionTrouble Area
P0335
No crankshaft position sensor (NE) signal to ECM during
cranking for 3 sec. or more (2 trip detection logic).
P0335No crankshaft position sensor (NE) signal to ECM with engine
speed 600 rpm or more (2 trip detection logic).
Open or short in crankshaft position sensor circuit
P0339
In condition (a), (b) and (c), when no crankshaft position sen-
sor (NE) signal is input for 0.05 sec. or more
(1 trip detection logic):
(a) Engine revolution 1,000 rpm or more
(b) STA signal is OFF
(c) 3 sec. or more has been lapsed after STA signal is switched
from ON to OFF.

INSPECTION PROCEDURE
HINT:

Perform troubleshooting of DTC P0335 first. If no trouble is found, troubleshoot the engine mechanical
system.

Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle
was running or stopped, the engine was warmed up or not, the air±fuel ratio was lean or rich, etc. at
the time of the malfunction.
1 INSPECT CRANKSHAFT POSITION SENSOR(RESISTANCE)
(a) Disconnect the C6 crankshaft position sensor connector.
(b) Measure the resistance between the terminals of the
crankshaft position sensor.
Resistance:
985 to 1,600 at cold
1,265 to 1,890 at hot
NOTICE:
ºColdº and ºHotº shown above mean the temperature of
the coils themselves. ºColdº is from ±10C (14F) to 50C
(122F) and ºHotº is from 50C (122F) to 100C (212F).

These DTCs indicate a malfunction related to primary circuit.

If DTC P0351 is displayed, check No. 1 ignition coil with igniter circuit.

If DTC P0352 is displayed, check No. 2 ignition coil with igniter circuit.

If DTC P0353 is displayed, check No. 3 ignition coil with igniter circuit.

If DTC P0354 is displayed, check No. 4 ignition coil with igniter circuit.
CIRCUIT DESCRIPTION
A Direct Ignition System (DIS) has been adopted. The DIS improves the ignition timing accuracy, reduces
high±voltage loss, and enhances the overall reliability of the ignition system by eliminating the distributor.
The DIS is a 1±cylinder ignition system which ignites one cylinder with one ignition coil. In the 1±cylinder
ignition system, the one spark plug is connected to the end of the secondary winding. High voltage generated
in the secondary winding is applied directly to the spark plug. The spark of the spark plug passes from the
center electrode to the ground electrode.
The ECM determines the ignition timing and outputs the ignition signals (IGT) for each cylinder. Based on
the IGT signals, the power transistors in the igniter cut off the current to the primary coil in the ignition coil
is supplied to the spark plug that is connected to the end of the secondary coil. At the same time, the igniter
also sends an ignition confirmation signal (IGF) as a fail±safe measure to the ECM.
