DTC P0335 CRANKSHAFT POSITION SENSOR ºAº
CIRCUIT MALFUNCTION
DTC P1335 CRANKSHAFT POSITION SENSOR CIRCUIT
MALFUNCTION (DURING ENGINE
RUNNING)
CIRCUIT DESCRIPTION
The crankshaft position sensor (NE signal) consists of a magnet, iron core and pick up coil.
The NE signal plate (crankshaft timing pulley) has 34 teeth and is installed to the crankshaft. The NE signal
sensor generates 34 signals at every engine revolution. The ECM detects the crankshaft angle and the en-
gine revolution based on the NE signals, and the cylinder and the angle of the VVT based on the combination
of the G2 and NE signals.

DTC P0325 KNOCK SENSOR 1 CIRCUIT MALFUNCTION
(BANK 1)
CIRCUIT DESCRIPTION
Knock sensor is fitted on the cylinder block to detect the engine knocking. This sensor contains a piezoelec-
tric element which generates a voltage when it becomes deformed, which occurs when the cylinder block
vibrates due to knocking. If engine knocking occurs, the ignition timing is delayed to suppress it.
DTC No.DTC Detecting ConditionTrouble Area
P0325No knock sensor signal to the ECM with engine speed 3,000
rpm or more
Open or short in knock sensor circuit

Knock sensor (under±torqued or loose)

ECM
HINT:
If the ECM detects the DTC ºP0325º, it enters the fail±safe mode in which the corrective retarded angle value
is set to the maximum value.
Reference:
Inspection using the oscillascope.
(1) Run the engine at 4,000 rpm, check the waveform
between terminal KNKL of the ECM connector and
body ground.
HINT:
The correct waveform is as shown on the left.
(2) Spread the time on the horizontal axis, and confirm
that period of the wave is 80
seconds (Normal
mode vibration frequency of knock sensor: 11.7
kHz).
HINT:
If the vibration frequency in the normal mode is not 11.7 kHz,
the sensor is out of order.
