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).

(BANK 1 OR SINGLE SENSOR)
DTC P0328 KNOCK SENSOR 1 CIRCUIT HIGH INPUT
(BANK 1 OR SINGLE SENSOR)
CIRCUIT DESCRIPTION
A flat type knock sensor (non±resonant type) has a structure that can detect vibrations in a wide frequency
range, from about 6 kHz to 15 kHz, and has the following features.
Knock sensor is fitted on the cylinder block to detect the engine knocking.
The knock sensor contains a piezoelectric element which generates a voltage when it becomes deformed.
This occurs when the cylinder block vibrates due to knocking. If engine knocking occurs, the ignition timing
is retarded to suppress it.
DTC No.DTC Detection ConditionTrouble Area

threshold. (Threshold varies according to an engine speed.)
