EVAPORATIVE EMISSION CANISTER AND FUEL TANK PRESSURE RELIEF VALVE REMOVAL AND INSTALLATION INSPECTION EVAPORATIVE EMISSION VENTILATION SOLENOID CHECK Connect a hand vacuum pump to nipple (A) of the solenoid. Check air tightness by applying a vacuum with voltage applied directly from the battery to the evaporative emission ventilation solenoid and without applying voltage. VACUUM CONDITION CHART BATTERY VOLTAGE NORMAL CONDITION Applied Vacuum maintained Not applied Vacuum leaks Measure the resistance between the terminals of the solenoid. Standard value: 17 - 21 ohm [at 20°C (68°F)] CATALYTIC CONVERTER GENERAL DESCRIPTION (CATALYTIC CONVERTER) 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 provides the highest purification against the three constituents, namely, CO, HC and NOx. REMOVAL AND INSTALLATION Required Special Tool: MD998770: Oxygen Sensor Wrench REMOVAL SERVICE POINT < >HEATED OXYGEN SENSOR (FRONT) REMOVAL Use special tool MD998770 to remove the oxygen sensor. INSTALLATION SERVICE POINT >> A < Use special tool MD998770 to installation the oxygen sensor.
