How to replace the O2 sensor on Hyundai Santa Fe?
There are 2 sensors “upstream” (on the manifold) and 2 “downstream” (one on each converter for the manifold). Unplug the electrical wiring that connects to the O2 sensors. These are plug-style connectors. Squeeze the release tab and pull them off the sensor. Unbolt the O2 sensor as you would any other bolt, but use an O2 sensor tool.
What happens when you change the O2 sensor?
The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it.
When do you Know Your oxygen sensor is bad?
The first indication of a problem with your vehicle’s oxygen sensor is often when the “check engine” light comes on. Failing sensors cause jerky movements, trouble starting, and reduced fuel efficiency if they aren’t replaced. Oxygen sensors are necessary for vehicles to combine the proper ratio of gas and oxygen into fuel.
How often do oxygen sensors need to be replaced?
If one fails, chances are the other ones will fail soon too, so try to keep them on the same maintenance schedule. Oxygen sensors need to be replaced approximately every 100,000 mi (160,000 km) for vehicles manufactured after the year 2000. For older vehicles, change them every 60,000 mi (97,000 km) or earlier.
