PRECAUTION
1. INITIALIZATION
NOTICE:
• Perform RESET MEMORY (AT initialization) when
replacing the automatic transaxle assembly, engine
assembly or ECM (See page AX-16).
• Perform REGISTRATION (VIN registration) when
replacing the ECM (See page ES-15).
HINT:
Initialization cannot be completed by only removing the
battery.
2. FOR USING INTELLIGENT TESTER
CAUTION:
Observe the following items for safety reasons:
• Before using the tester, read the instruction
manual.
• Prevent the tester cable from being caught on the
pedals, shift lever and steering wheel when
driving with the tester connected to the vehicle.
• When driving the vehicle for testing purposes
using the tester, two persons are required. One is
for driving the vehicle, and the other operates the
tester.
3. FOR USING BATTERY DURING INSPECTION
(a) While using the battery during inspection, do not
bring the positive and negative tester probes too
close to each other as a short circuit may occur.
4. COOLING FAN SYSTEM
NOTICE:
• When the ignition switch is turned off and the engine
temperature is high, the cooling fans may operate for
approximately 3 minutes.
• After turning the ignition switch off, keep hands and
objects away from the fans when they are operating.
HINT:
If all of the following are met for a certain period of time during
a few minute period immediately before the engine is
stopped, the electric fans will continue to operate for 3
minutes after the engine is stopped. This is performed to
ensure restartability and stabilize idle speed.
– The intelligent tester indicates a very high coolant
temperature.
– The intelligent tester indicates a high outside air
temperature.
– The vehicle has been driven under high load (driving on an
uphill or equivalent).
The following sensors are used for this control:
– Coolant temperature sensor
– Outside air temperature sensor
–MAF sensor
– Vehicle speed sensors

DESCRIPTION
The exhaust camshaft's Variable Valve Timing (VVT) sensor consists of a magnet and MRE (Magneto
Resistance Element).
The exhaust camshaft has a sensor plate with 3 teeth on its outer circumference.
When the exhaust camshaft rotates, changes occur in the air gaps between the 3 teeth and MRE, which
affects the magnet. As a result, the resistance of the MRE material fluctuates. The VVT sensor converts
the exhaust camshaft rotation data to pulse signals, uses the pulse signals to determine the camshaft
angle, and sends it to the ECM.
MONITOR DESCRIPTION
If no signal is transmitted by the VVT (for exhaust camshaft) sensor despite the engine revolving, or the
rotations of the exhaust camshaft and the crankshaft are not synchronized, the ECM interprets this as a
malfunction of the sensor.
