1. Maintain the normal temperature and idling state by
operating the engine.
2. Connect the ECM terminal No. 11 and No. 34 and
check for normal operation through the output waves
using oscilloscope.Notice:Test during purge control valve operation after
the minimum of 1 minute after the engine turned on.
3. Connect the ECM terminal No. 34 and No.10 and
check for current consumption during the ignition
switch ON.
Specified Value
0.3 ~ 0.5 A
4. Remove the line to canister and measure the pres-
sure with the vacuum pressure gauge.
Specified Value

DInspection the cooling fan
DInspection the ECM
Circuit Description
Ignition voltage is supplied directly to the cooling fan relay coil. The ECM controls the relay by grounding the control
circuit. When the ECM is commanding a command ON, the voltage of the control circuit should be low (near 0 volt).
When the ECM is commanding the control circuit should be high (near battery voltage). If the fault detection circuit
senses a voltage other than what is expected, the fault line status will change causing the fault code to set.

Circuit Description
Battery voltage is supplied to the TCS warning lamp with the ignition in ON and START. The warning lamp can be
activated only by the Electrical Brake Control Module (EBCM) internally supplying ground to terminal 32. If the TCS
input circuit is open or short, this failure codewill be set.

OXYGEN SENSOR
YAA1F650
The oxygen sensor is unique among the engine control sensors because is acts like a battery and is able to generate
its own low voltage signal. It is located the exhaust system and monitors the amount of oxygen in the exhaust stream
and provides feedback to the Engine Control Module (ECM).
The electrically heated oxygen sensor warms up quickly and remains hot, even at idle when the exhaust manifold may
cool down.
The ECM applies a reference voltage of 450 mv to the
oxygen sensor, the ECM compares this reference volt-
age with the voltage generated by oxygen sensor. The
amount of voltage the oxygen sensor generates is pro-
portionate to the difference between the amount of oxy-
gen in the outside air and the exhaust gases. The
atmosphere contains about 21% oxygen. The exhaust
from a rich air/fuel ratio contains almost no oxygen. With
a large difference between the amounts of oxygen con-
taining the two surface, the sensor generates less volt-
age. When the exhaust gas is rich (below 14.7:1), the
voltage output is high, above 450 mv. When the exhaust
gas is lean (above 14.7:1 air/fuel ratio), the sensor ’s
voltage output is low, below 450 mv.
The ECM uses oxygen sensor information for:
DOpen loop / closed loop criteria
DIdeal air / fuel ratio
