Product Description

Oxygen sensor 234-9009
o2 sensor 234-9009
Replace oxygen sensor
Oxygen sensor notice
  • Heated oxygen sensors should be checked or replaced every 60,000 miles, while unheated oxygen sensors should be checked or replaced every 30,000 miles

  • It is best to replace O2 sensors in pairs. Because, replacing one sensor will cause the ECU to set a code for the other sensors. This is because the new sensor switching activity is much faster than that of the older aged sensors

  • If you are using an open end wrench, try an O2 socket. If this fails, try a long ratchet or breaker bar in conjunction with your socket to generate more torque. After the sensor is removed, be sure to use a thread cleaner to clean up the bung threads

  • 1 Oxygen sensor circuit failure

    2 The mixture is too rich

    3 The mixture is too lean

    4 The three-way catalytic converter is damaged or fails

    5 Damaged ECM

Fit and worked with my Veloster. Went from 16-21 MPG to 26-40 MPG. Get a blue flame torch and a 7/8" 12 point wrench to take the old o2 sensor off, nearly stripped it using every other method. You'll also need a special tool to put this on.

For a quarter of the price from a big box auto parts store I managed to include all of my maintenance parts in the budget for just the o2 sensor. Had a terrible hesitation on acceleration with misfire cels, once installed there was an immediate night and day difference. Gti is running as it always had again. Will need to replace the downstream sensor as well but the immediate improvement is enough for me to buy from this store again. Thank you!

Had a code P2197 , Bank 2 sensor 1 O2 sensor stuck lean. Replaced with this sensor and truck running good again.Will need a 22mm offset o2 sensor socket to make installation go smoother.

I got put on and need the picture if have Ford f150 it going to have a challenge it's few inches shorter, it can be do and you need to zip tie it the best you can way from the hot exhaust.. the extra 3 inches makes a difference, I will repost in 3 to 4 weeks let you about the durability..I do like the adjustable rubber pieces around you to zip tie and secure it well.The value will come in time .It was easy to use and replace.

Installed on a 2007 Jetta 2.5. The wiring is just barely long enough, but it does work. See attached photo. Overall a good purchase.
