Troubleshooting

Persistent Check Engine Light after installation

Setup, Compatibility & Care

Before installation, ensure the engine is completely cool to prevent contact with hot exhaust components. Always consult your vehicle's service manual to locate the sensor within the exhaust system, as it typically requires a specialized deep-well socket for removal and installation. Ensure the electrical connector is clean and free of corrosion before plugging in the new unit. To maintain performance, avoid spraying harsh chemicals or degreasers directly onto the sensor tip, as this can contaminate the internal elements. Always verify that your specific engine code matches the compatibility chart provided by your vehicle manufacturer or an authorized dealer before attempting installation.
