FAQs
How do I know if this sensor is compatible with my car?
Use the manufacturer's online make and model lookup tool to confirm that part 94268 is specified for your exact vehicle configuration.
Do I need a special tool to install this?
While an open-end wrench can sometimes work, using a dedicated oxygen sensor socket is highly recommended to prevent stripping the sensor housing.
Can I touch the tip of the sensor during installation?
No, you should avoid touching the sensor tip, as oils from your skin can contaminate the element and lead to inaccurate readings.
Does this sensor come with anti-seize pre-applied?
Check the threads of the new sensor; if they are bare, apply a very light coat of high-temperature anti-seize, ensuring none touches the sensor probe.
What is the purpose of the 4 wires?
Two wires are for the sensor's signal output, and two wires provide power and ground to the internal heating element.
Troubleshooting
Check Engine light remains on after installation
Use an OBD-II scanner to clear old trouble codes, as the computer may need to be manually reset to recognize the new sensor.
Poor fuel economy or engine hesitation
Verify that the electrical connector is fully seated and that the wiring is not pinched or damaged during routing.

Setup, Compatibility & Care
To ensure proper function, always verify that your vehicle's make and model matches the specifications listed for the 94268 part number.
- Preparation: Work on a cool engine to avoid exhaust burns.
- Removal: Disconnect the negative battery terminal and use an oxygen sensor socket to gently loosen the existing unit.
- Installation: Apply a small amount of anti-seize compound to the threads if it is not pre-applied, taking care not to contaminate the sensor tip.
- Connection: Route the 310 mm wire away from hot exhaust components to prevent melting, then secure the electrical connector firmly.
- Reset: After installation, clear any existing trouble codes using an OBD-II scanner to ensure the ECU recognizes the new sensor data.
