Extended Product Information

FAQs

Does this sensor come with anti-seize already applied?

Yes, genuine NGK NTK sensors typically feature factory-applied anti-seize on the threads; do not add more.

Can I use this on any vehicle?

No, this sensor is specific to certain vehicle makes and models. Always use the compatibility tool before purchase.

What is the purpose of a broadband oxygen sensor?

A broadband sensor provides a wider range of air-fuel ratio data compared to standard narrow-band sensors.

How long should a Lambda sensor last?

While it depends on driving conditions, many manufacturers suggest testing or replacing sensors between 80,000 and 100,000 miles.

Is the 1500 mm cable length enough for all applications?

The length is standard for many models, but verify your vehicle's specific cable routing requirements.

Troubleshooting

Check Engine Light (CEL) remains on after replacement

Clear the diagnostic trouble codes (DTC) using an OBD-II scanner after installing the new sensor.

Sensor signal is erratic or non-responsive

Check the wiring harness for signs of melting, cuts, or loose connections at the 5-circuit plug.

Engine running rough after install

Ensure the sensor is fully threaded into the exhaust port and the connector is clicked firmly into place.

Pros and Cons

Pros

  • High-accuracy oxygen monitoring
  • Durable construction for harsh exhaust conditions
  • Ample cable length for versatile installation
  • Meets or exceeds OE specifications

Cons

  • Requires professional installation for best results
  • Specific vehicle compatibility is limited
  • Fragile sensing element requires careful handling

Setup, Compatibility & Care

Before starting your installation, ensure the vehicle engine is cool to the touch. Use the official NGK NTK vehicle compatibility tool to confirm that UAR9000-EE017 matches your engine code. During installation, use an appropriate O2 sensor socket to avoid damaging the sensor housing or threads. Never use standard lubricants or sealants on the threads unless pre-applied by the manufacturer, as these can contaminate the sensor. Ensure the cable is secured away from hot exhaust manifolds using factory-standard heat shielding clips. Regularly check the connector for corrosion or loose pins during routine maintenance intervals to maintain signal integrity.
