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.

DTC P0010 CAMSHAFT POSITION ºAº ACTUATOR
CIRCUIT (BANK 1)
HINT:
This is the procedure of oil control valve (OCV).
CIRCUIT DESCRIPTION
The VVT system controls the intake camshaft to provide the optimal valve timing for every driving condition. This control
is performed based on the signals, such conditions as intake air volume, throttle position and engine coolant tempera-
ture.
The ECM controls the oil control valve (OCV), based on the signals output from the sensors. The VVT controller regu-
lates the intake camshaft angle using oil pressure through the OCV. As result, the relative position between the camshaft
and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves, exhaust emissions de-
crease under overall driving conditions. Also, the ECM detects the actual valve timing using the signals from the cam-
shaft position sensor and the crankshaft position sensor, and performs feedback control. This is how target valve timing
is achieved by the ECM.

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.

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).

CIRCUIT DESCRIPTION
The Electronic Driver Unit (EDU) has been adopted to operate the injector at high speed. The EDU enables
the injector to drive in high±speed rate under high±pressure fuel condition using its internal DC/DC converter
that provides high voltage and quick±charging system.
The ECM constantly monitors the EDU. If the ECM detects abnormal condition, it will stop the engine.
