If DTC ºP0011/59 or P0012/59º is displayed, check VVT system circuit.

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 deter\
mining whether the vehicle
was running or stopped, the engine was warmed up or not, the air±fuel ra\
tio was lean or rich, etc. at
the time of the malfunction.

CIRCUIT (BANK 1 OR SINGLE SENSOR)
DTCP0341/12CAMSHAFT POSITION SENSOR ºAº CIRCUIT RANGE/PERFORMANCE (BANK 1
OR SINGLE SENSOR)
CIRCUIT DESCRIPTION
The camshaft position sensor (G signal) consists of a magnet, iron core a\
nd pickup coil.
The G signal rotor has 3 teeth on its outer circumference and is install\
ed on the intake camshaft.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pickup coil changes,
causing fluctuations in the magnetic field and generating an electromoti\
ve force in the pickup coil.
The NE signal plate (crankshaft position sensor plate) has 34 teeth an\
d is installed to the crankshaft. The
NE signal sensor generates 34 signals at every engine revolution. The EC\
M detects the crankshaft angle
and the engine revolution based on the NE signals, and the cylinder and the\
angle of the VVT based on the
combination of the G and NE signals.

INSPECTION PROCEDURE
HINT:
Hand±held tester only:
Narrowing down the trouble area is possible by performing the ºA/F CONTROLº ACTIVE TEST (heated oxy-
gen sensor or other trouble areas can be distinguished).
(a) Perform ACTIVE TEST using the hand±held tester (A/F CONTROL).
HINT:
ºA/F CONTROLº is an ACTIVE TEST which changes the injection volume\
±12.5 % or +25 %.
(1) Connect the hand±held tester to the DLC3 on the vehicle.
(2) Turn the ignition switch ON.
(3) Warm up the engine by running the engine at 2,500 rpm for approximately 9\
0 sec.
(4) Select the item ºDIAGNOSIS / OBD/MOBD / ACTIVE TEST / A/F CONTROLº\
.
(5) Perform ºA/F CONTROLº with the engine in an idle condition (press\
the right or left button).
Result:
Heated oxygen sensor reacts in accordance with increase and decrease of injection volume:
+25 %
rich output: More than 0.55 V
±12.5 %
lean output: Less than 0.4 V
