1. General
Each cylinder of this engine has 2 intake valves and 2 exhaust valves. Intake and exhaust efficiency is
increased due to the larger total port areas.
This engine uses roller rocker arms with built-in needle bearings. This reduces the friction that occurs
between the cams and the areas (roller rocker arms) that push the valves down, thus improving fuel
economy.
A hydraulic lash adjuster, which maintains a constant zero valve clearance through the use of oil pressure
and spring force, is used.
The intake camshafts are driven by the crankshaft via the primary timing chain. The exhaust camshafts
are driven by the intake camshaft of the respective bank via the secondary timing chain.
This engine uses a Dual VVT-i (Variable Valve Timing-intelligent) system which controls the intake and
exhaust camshafts to provide optimal valve timing according to driving conditions. With this adoption,
lower fuel consumption, higher engine performance, and fewer exhaust emissions have been achieved.
For details of Dual VVT-i control, see page EG-120.

2. Camshaft
The camshafts are made of cast iron alloy.
An oil passage is provided on the intake and exhaust camshafts in order to supply engine oil to the VVT-i
system.
A VVT-i controller has been installed on the front of the intake and exhaust camshafts to vary the timing
of the intake and exhaust valves.
Together with the use of the roller rocker arm, the cam profile has been designed with an indented R
(radius). This results in increased valve lift when the valve begins to open and finishes closing, helping
to achieve enhanced output performance.

2. CATALYST MONITOR (ACTIVE AIR-FUEL RATIO
CONTROL TYPE)
(a) Preconditions
The monitor will not run unless:
• The MIL is OFF.
(b) Drive Pattern
(1) Connect the intelligent tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Turn the tester ON.
(4) Clear DTCs (if set) (see page ES-35).
(5) Start the engine and warm it up.
(6) Drive the vehicle at between 40 mph and 70 mph
(64 km/h and 113 km/h) for at least 10 minutes.
(c) Monitor Status
Check the Readiness Monitor status displayed on
the tester.
If the status does not switch to COMPL (complete),
extend the driving time.
3. EVAP SYSTEM MONITOR (KEY OFF TYPE)
(a) Preconditions
The monitor will not run unless:
– The fuel tank is less than 90% full.
– The altitude is less than 8,000 ft. (2,450 m).
– The vehicle is stationary.
– The engine coolant temperature is between
4.4
C and 35C (40F and 95F).
– The intake air temperature is between 4.4
C and
35
C (40F and 95F).
– Vehicle was driven in a city area (or on freeway)
for 10 minutes or more.

– Air-fuel ratio feedback control is performed.
(b) Drive Pattern for front A/F sensor and HO2 sensor
(1) Connect the intelligent tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Turn the tester ON.
(4) Clear DTCs (see page ES-35).
(5) Start the engine, and warm it up until the ECT
reaches 75
C (167F) or higher.
(6) Drive the vehicle at between 60 km/h (38 mph)
and 120 km/h (75 mph) for at least 10 minutes.
(7) Change the transmission to 2nd gear.
(8) Accelerate the vehicle to 64 km/h (40 mph) or
more by depressing the accelerator pedal for at
least 10 seconds.
(9) Soon after performing step (8) above, release
the accelerator pedal for at least 4 seconds without
depressing the brake pedal, in order to execute fuel-
cut control.
(10) Allow the vehicle to decelerate until the vehicle
speed declines to less than 10 km/h (6 mph).
(11) Repeat steps from (8) through (10) above at
least 3 times in one driving cycle.
(c) Monitor Status
(1) Check the Readiness Monitor status displayed
on the tester.
(2) If the status does not switch to COMPL
(complete), make sure that the preconditions
have been met, and then perform steps from (5)
through (11) in the Drive Pattern above.
