CEL-Fix Adaptador for Sensores de lambda com HJS Euro4 Catalizador

This Oxygen Sensor CEL-Fix is a solution for vehicles com titanium oxide sensors or "smart" Engine Control Units (ECUs) com sophisticated checks where an electronic oxygen sensor simulator cannot achieve the desired results. It is universal e applies to almost all EOBD vehicles which have two oxygen sensors (one before e one after the catalytic converter). This CEL-Fix is used to restore a normal signal for the oxygen sensor after the catalytic converter when the catalyst is removed or replaced com a racing catalyst resulting in an error message (CEL-Check Engine Light) in the controller. Unlike simple designs that place the sensor just a abit away from the exhaust gas stream e prevent the CEL only for short term, the CEL-Fix has an integrated mini-cat which actually improves the exhaust gas quality before it is measured by the sensor. It comes com an Oxygen Sensor Standard Thread M18x1, 5 on each side. Warning: The first oxygen sensor (nearest to the engine) located in front of the catalytic converter must never be replaced, since it is responsible for proper formation of the mixture! On engines com two separate e parallel working catalytic converters, two (2) sensors must be used.
