2GR-FE ENGINE CONTROL SYSTEM – SFI SYSTEMES–83
ES
DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, Oil Control Valve (OCV) and VVT controller.
The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil
pressure supplied to the VVT controller. Camshaft timing control is performed according to engine
operating conditions such as intake air volume, throttle valve position and engine coolant temperature.
The ECM controls the OCV, based on the signals transmitted by several sensors. The VVT controller
regulates the intake camshaft angle using oil pressure through the OCV. As a result, the relative positions
of the camshaft and crankshaft are optimized, the engine torque and fuel economy improves, and the
exhaust emissions decrease under overall driving conditions. The ECM detects the actual intake valve
timing using signals from the camshaft and crankshaft position sensors, and performs feedback control.
This is how the target intake valve timing is verified by the ECM.

When multiple DTCs for misfiring cylinders are set, but DTC P0300 is not set, it indicates that misfires
have been detected in different cylinders at different times. DTC P0300 is only set when several misfiring
cylinders are detected at the same time.
MONITOR DESCRIPTION
The ECM illuminates the MIL and sets a DTC when either one of the following conditions, which could
cause emission deterioration, is detected (2 trip detection logic).
• Within the first 1000 crankshaft revolutions of the engine starting, an excessive misfiring rate
(approximately 20 to 50 misfires per 1000 crankshaft revolutions) occurs once.
• An excessive misfiring rate (approximately 20 to 50 misfires per 1,000 crankshaft revolutions) occurs a
total of 4 times.
The ECM flashes the MIL and sets a DTC when either one of the following conditions, which could cause
the Three-Way Catalytic Converter (TWC) damage, is detected (2 trip detection logic).
• At a high engine rpm, a catalyst damage misfire, which monitored every 200 crankshaft revolutions,
occurs once.
• At a normal engine rpm, a catalyst damage misfire, which monitored every 200 crankshaft revolutions,
occurs 3 times.
HINT:
If a catalyst damage misfire occurs, the ECM informs the driver by flashing the MIL.

INSPECTION PROCEDURE
HINT:
• If no problem is found by this diagnostic troubleshooting procedure, troubleshoot the engine
mechanical systems.
• Check the engine speed. The engine speed can be checked by using the intelligent tester. Perform the
following procedure:
(a) Connect the intelligent tester to the DLC3.
(b) Start the engine.
(c) Turn the tester on.
(d) Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / PRIMARY /
ENGINE SPD.
The engine speed may be indicated as zero despite the engine revolving normally. This is caused
by a lack of NE signals from the Crankshaft Position (CKP) sensor. Alternatively, the engine speed
may be indicated as lower than the actual engine speed, if the CKP sensor voltage output is
insufficient.
• Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame
data can be helpful in determining whether the vehicle was running or stopped, whether the engine
was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the
time of a malfunction.
(a) Disconnect the C22 Crankshaft Position (CKP) sensor
connector.
(b) Measure the resistance according to the value(s) in the
table below.
Standard resistance
HINT:
Terms "cold" and "hot" refer to the temperature of the
coils. "Cold" means approximately -10 to 50
C (14 to
122
F). "Hot" means approximately 50 to 100C (122 to
212
F).
(c) Reconnect the CKP sensor connector.
