CEL-Fix Adattatore  per Sonde Lambda con HJS Euro4 Catalizzatore

This Oxygen Sensor CEL-Fix is a solution  per vehicles con titanium oxide sensors  o"smart" Engine Control Units (ECUs) con sophisticated checks where an electronic oxygen sensor simulator cannot achieve the desired results.It is Universale  eapplies to almost all EOBD vehicles which have two oxygen sensors (one before  eone after the catalytic converter). This CEL-Fix is used to restore a normale signal  per the oxygen sensor after the catalytic converter when the catalyst is removed  oreplaced con 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  eprevent the CEL only  per 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 con 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  per proper formation of the mixture! On engines con two separate  eparallel working catalytic converters, two (2) sensors must be used.
