EXHAUST GAS/OUTSIDE ODOR DETECTING SENSOR


Description


COMPONENT DESCRIPTION





The exhaust gas/outside odor detecting sensor (1) is attached on the radiator core support. It detects smell of exhaust gas and unpleasant odor, and converts it into a duty ratio which is then input into the unified meter and A/C amp.

STRUCTURE AND OPERATION
Exhaust gas/outside odor detecting sensor detects ambient atmospheric CO, NO2 and unpleasant odor, and converts them to values of resistance. The values are converted to signals with the exhaust gas/outside odor detecting sensor internal circuit, then the unified meter and A/C amp. inputs the signals.
Exhaust gas/outside odor detecting sensor has a construction that detects CO, NO2 and unpleasant odor by exhaust gas/outside odor detecting sensor element from the air intake of the case through a filter (waterproof sheet). It sends output signals to the unified meter and A/C amp. in response to a resistance value conversion by exhaust gas/outside odor detecting sensor elements. Unified meter and A/C amp. prevent a smell of exhaust gas and ambient atmospheric unpleasant odor from getting into vehicle by performing corrections according to various driving conditions.
