3. CHECK WHETHER DTC OUTPUT RECURS (DTC P0351, P0352, P0353, P0354, P0355, P0356,
P0357 OR P0358)
a. Connect the Techstream to the DLC3.
b. Turn the ignition switch to ON and turn the Techstream ON.
c. Clear DTCs (see DTC CHECK/CLEAR ).
d. Shuffle the arrangement of the ignition coils with igniters (among No. 1 to No. 8 cylinders).
e. Perform a simulation test.
f. Check DTCs displayed on the Techstream.

DESCRIPTION
The exhaust camshaft's Variable Valve Timing (VVT) sensor (EV1, 2 signal) consists of a magnet and MRE
(Magnetic Resistance Element).
The exhaust camshaft has 3 teeth on its outer circumference. When the exhaust camshaft rotates, changes occur
in the air gaps between the teeth and MRE, which affects the magnetic field. As a result, the resistance of the
MRE material fluctuates. The VVT sensor converts the exhaust camshaft rotation data into pulse signals, uses
the pulse signals to determine the camshaft angle, and sends it to the ECM.

WAVEFORM REFERENCE
HINT:
EV1+ and EV2+ stand for the VVT sensor signal, and NE+ stands for the CKP sensor signal.
MONITOR DESCRIPTION
If no signal is transmitted by the VVT sensor despite the engine revolving, or the rotations of the camshaft and
the crankshaft are not synchronized, the ECM interprets this as a malfunction of the sensor.
