INSPECTION

M1173004900141

EVAPORATIVE EMISSION VENTILATION
SOLENOID CHECK

1. Connect a hand vacuum pump to nipple (A) of the solenoid.
2. Check air tightness by applying a vacuum with voltage

applied directly from the battery to the evaporative emission
ventilation solenoid and without applying voltage.

3. Measure the resistance between the terminals of the

solenoid.

Standard value: 17

− 21 Ω [at 20°C (68°F)]

CATALYTIC CONVERTER

GENERAL DESCRIPTION (CATALYTIC CONVERTER)

M1173005300131

The three way catalytic converter, together with the
closed loop air-fuel ratio control based on the oxygen
sensor signal, oxidizes carbon monoxides (CO) and
hydrocarbons (HC), also reduces nitrogen oxides
(NOx).

When the mixture is controlled at stoichiometric
air-fuel ratio, the three way catalytic converter pro-
vides the highest purification against the three con-
stituents, namely, CO, HC and NOx.
