CEL-Fix Adaptateur pour Sondes Lambda avec HJS Euro4 Catalyseur

This Oxygen Sensor CEL-Fix is a solution pour vehicles avec titanium oxide sensors  ou "smart" Engine Control Units (ECUs) avec sophisticated checks where an electronic oxygen sensor simulator cannot achieve the desired results.It is Universel etapplies to almost all EOBD vehicles which have two oxygen sensors (one before etone after the catalytic converter). This CEL-Fix is used to restore a normal signal pour the oxygen sensor after the catalytic converter when the catalyst is removed  ou replaced avec 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 etprevent the CEL only pour 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 avec 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 pour proper formation of the mixture! On engines avec two separate etparallel working catalytic converters, two (2) sensors must be used.
