GAS SENSOR


Description


COMPONENT DESCRIPTION

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






Gas Sensor Circuit






SMELL OF EXHAUST GAS INPUT PROCESS
Gas sensor detects ambient atmospheric CO and NO2, and converts them to values of resistance. The values are converted to signals with the gas sensor internal circuit, then the unified meter and A/C amp. inputs the signals.





Gas sensor has a construction that detects CO and NO2 by gas 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 gas sensor elements. Output signals prevent a smell of exhaust gas from getting into vehicle by performing corrections according to various driving conditions.
