FAQs
Does the 840 mm lead length fit all vehicles?
No, the length is vehicle-specific. Please verify compatibility with your vehicle's part requirements before purchase.
Can I use anti-seize on the threads?
Only use high-temperature, sensor-safe anti-seize on the threads, and be extremely careful not to get any on the sensor tip.
How often should I replace this sensor?
While there is no fixed interval, symptoms like decreased fuel economy or a failed emissions test suggest it is time for a replacement.
What do the 4 circuits represent?
The circuits provide dedicated connections for the sensor signal, ground, and the internal heater element.
Is this a universal sensor?
No, this is a specific replacement part designed to meet or exceed OEM standards for compatible vehicles.
Troubleshooting
Check Engine Light remains on after installation
Clear the fault codes using an OBD-II scanner after installation; if the light persists, ensure the connector is fully seated.
Engine running rough after replacement
Verify that the wiring harness is not touching hot exhaust components and that the sensor connector is free of debris.

Setup, Compatibility & Care
Before installation, verify that the MPN 94615 matches your vehicle's specific engine and exhaust system requirements. When performing the setup: 1. Ensure the engine is cool to prevent burns. 2. Use a dedicated oxygen sensor socket to avoid damaging the housing. 3. Handle the sensor by the connector or metal body, never touching the sensor tip, as oils from your skin can cause premature failure. Always follow the manufacturer's specific torque requirements during installation to ensure a gas-tight seal. Regularly check the wiring harness and connectors for signs of heat damage or corrosion during routine vehicle maintenance.
