10-Pack O2 Sensor Spacer Adapter compatible with Catalytic Converter Bung

The O2 sensor fixture contains a miniature catalytic converter designed to help reduce emissions if the main catalytic converter is damaged. This device helps prevent the check engine light from illuminating due to catalytic converter efficiency issues. Avoid using unreliable extensions, as they often fail to function properly. This unit features a built-in mini catalytic converter compatible with improved percompatible withmance. The O2 sensor fixture with a mini catalytic converter signals the ECU to recognize the presence of a functioning catalytic converter. When the catalytic converter is removed, the downstream O2 sensor may detect increased exhaust temperatures and higher levels of unburned fuel, which can trigger a check engine light (CEL, SES, DTC) with diagnostic trouble codes such as P0420 (catalyst system efficiency below threshold bank 1) and/or P0430. In some cases, check engine light alerts may be caused by O2 sensor malfunctions, leading to additional error codes. This CEL eliminator (commonly referred to as a mini cat) is designed to address certain P0420 codes related to catalytic converter efficiency. Features: 1.
