Catalytic Converter And Over-Temperature Control System: Description

LUV models use a catalytic converter on all California vehicles to reduce hydrocarbon and carbon monoxide emissions. The converter is mounted in front of muffler in exhaust system.

On California vehicles an over-temperature control system is used to sense catalyst temperature and help prevent temperature buildup. Over-temperature control system consists of a thermo sensor, thermo controller, vacuum switching valve, air switching valve, coasting fuel cut device, and engine speed sensor.
