  • Ensure you have the right part with the right wire length for your vehicle.
  • Excess wire can be exposed to extreme heat and abrasions that can lead to premature wire harness failure.
  • Regularly inspect oxygen sensors for signs of damage or wear and replace them if signs of damage are found

Signs of wear for oxygen sensors include but are not limited to:

  • Check engine light illuminated
  • Poor engine performance
  • Poor fuel economy

Frequently Asked Questions

Yes, always consult the Vehicle Owner's manual or an expert technician before making any repairs or adjustments.

Yes, an oxygen sensor can fail. Most sensors slowly degrade in performance and send a false rich signal to the ECU, running the engine too lean.

A universal oxygen sensor operates the same as the original equipment sensor; however, it does NOT come equipped with an OEM-style connector. Installation requires splicing the original equipment connector to the oxygen sensor.

Yes, fuel additives and injector cleaners that are labeled as oxygen sensor safe may be used in sensor-equipped vehicles. Use of additives not labeled as oxygen sensor safe can damage your oxygen sensor.

Yes, your vehicle may possibly have up to six or more sensors.
