CIRCUIT DESCRIPTION
To obtain a high purification rate for the CO, HC and NOx components of the exhaust gas, a three−way cata-
lytic converter is used. For the most efficient use of the three−way catalytic converter, the air−fuel ratio must
be precisely controlled so that it is always close to the stoichiometric air−fuel ratio.
The heated oxygen sensor has the characteristic whereby its output voltage changes suddenly in the vicinity
of the stoichiometric air−fuel ratio. This is used to detect the oxygen concentration in the exhaust gas and
to provide the ECM with feedback to control the air−fuel ratio.
When the air−fuel ratio becomes LEAN, the oxygen concentration in the exhaust gas increases. And the
heated oxygen sensor informs the ECM of the LEAN condition (low voltage, i. e. less than 0.45 V).
When the air−fuel ratio is RICHER than the stoichiometric air−fuel ratio, the oxygen concentration in the ex-
haust gas is reduced. And the heated oxygen sensor informs the ECM of the RICH condition (high voltage,
i. e. more than 0.45 V). The ECM judges whether the air−fuel ratio is RICH or LEAN by voltage from the
heated oxygen sensor, and controls the injection timing accordingly. However, if the malfunction of the
heated oxygen sensor causes abnormal voltage output, the ECM becomes unable to perform the accurate
air−fuel ratio control.
The heated oxygen sensors include a heater which heats the zirconia element. The heater is controlled by
the ECM. When the intake air volume is low (the temperature of the exhaust gas is low), the current flows
to the heater in order to heat the sensor for the accurate oxygen concentration detection.

INSPECTION PROCEDURE
HINT:
Hand−held tester only:
It is possible the malfunctioning area can be found using the ACTIVE TEST A/F CONTROL operation. The
A/F CONTROL operation can determine if the A/F sensor, heated oxygen sensor or other potential trouble
areas are malfunctioning or not.
(a) Perform the ACTIVE TEST A/F CONTROL operation.
HINT:
The A/F CONTROL operation lowers the injection volume12.5% or increases the injection volume 25%.
(1) Connect the hand−held tester to the DLC3 on the vehicle.
(2) Turn the ignition switch to ON.
(3) Warm up the engine by running the engine at 2,500 rpm for approximately 3 minutes.
(4) Select the item: DIAGNOSIS / OBD/MOBD / ACTIVE TEST / A/F CONTROL.
(5) Perform the A/F CONTROL operation with the engine in an idle condition (press the right or left
button).
Result:
Heated oxygen sensor reacts in accordance with increase and decrease of injection volume:
+25 %
rich output: More than 0.5 V
−12.5 %
lean output: Less than 0.4 V
NOTICE:
There is a delay of few seconds in the sensor1(front sensor) output, and there is about 20 seconds
delay at maximum in the sensor 2 (rear sensor).
