Engine Check Light Fix – Built-In Miniature Catalytic Converter [SNP07]

Engine Check Light Fix (SNP07) is an O2 sensor adaptor with an inbuilt miniature euro 4 catalytic converter, designed to help reduce or prevent false Check Engine Light (CEL) warnings—especially when using high-flow catalytic converters or while waiting on replacement parts. Available in Straight, 45° and 90° angles to simplify tight-space installations.

Key Features

• Built-in miniature catalytic converter to help minimise CEL triggers
• Enables use of high-flow catalytic converters on many late-model vehicles
• Choose your angle: Straight, 45°, or 90°
• Direct bolt-in to secondary/post-cat O2 sensor port
• Precision-machined body and threads for a reliable seal
• Durable construction suitable for daily use

Fitment & Application

Vehicles built from ~2000-on commonly use multiple oxygen sensors (e.g. two on most 4-cyl models and up to four on V6/V8 models). This adaptor is intended for the secondary (post-cat) O2 sensor, typically located immediately after the primary catalytic converter.

Installation Overview

1. Locate the secondary/post-cat O2 sensor (after the primary catalytic converter).
2. Carefully remove the O₂ sensor from the exhaust.
3. Thread the SNP07 adaptor into the O₂ bung, then reinstall the O₂ sensor into the adaptor.
4. Clear any stored fault codes if required and road test.

Tip: Select the angle (Straight/45°/90°) that provides the best clearance from heat shields, floors, or drivetrain components.
