Item Type: Sensor Filter Fitting_x000D_ Material: Stainless steel_x000D_ Product Size: male thread M18x1.5, female thread M18x1.5, Length: Approx. 46.5mm / 1.83in_x000D_ Function: Check engine light repair_x000D_ Weight: 37 g / 1.3 oz(approx.) 1FOR CHECKING: The micro catalytic converter integrated in the O2 cel jig helps to eliminate this annoying problem by light checking the engine after replacing the exhaust or removing the catalytic converter and sometimes even when installing the high flux catalytic converter 2MICRO AND COMPACT: Should not seize the opportunity just because length usually does not work, which is actually an integrated microcatalytic converter 3ACCURATE SENSING: Cel curing will make your ECU think the catalyst converter is still installed. When the catalytic converter is removed, the oxygen sensor will see an increase in temperature and unburned fuel flow 4TECHNICAL PARAMETERS: Therefore, to view the engine light (CEL SES DTC), the typical error codes are p0420 (catalysts with system efficiency below the cylinder bank 1 threshold) and/or p0430 p0420 (catalysts with system efficiency below the cylinder bank 2 threshold) for off road use only 5DURABLE CONSTRUCTION: This component is made of excellent stainless steel material to ensure reliable performance and long life1 x Sensor Filter Fitting
