CEL-Fix Adapter für Lambdasonden mit HJS Euro4 Katalysator

This Oxygen Sensor CEL-Fix is a solution für vehicles mit titanium oxide sensors  oder"smart" Engine Control Units (ECUs) mit sophisticated checks where an electronic oxygen sensor simulator cannot achieve the desired results.It is Universal  undapplies to almost all EOBD vehicles which have two oxygen sensors (one before  undone after the catalytic converter). This CEL-Fix is used to restore a normal signal für the oxygen sensor after the catalytic converter when the catalyst is removed  oderreplaced mit 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  undprevent the CEL only für 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 mit 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 für proper formation of the mixture! On engines mit two separate  undparallel working catalytic converters, two (2) sensors must be used.
