Just a simple how-to video on replacing your upstream oxygen sensor in a NG Saab 9-3 (phone battery died at the end, but the important bits are there). Even in the cold, it’s a straightforward process. Merry Christmas to my Saab!
Symptoms of a failing O2 sensor (could be in combination with other problems, e.g. spark plugs, coil packs, MAF sensor, dirty throttle body, etc.):
– less than usual fuel economy
– rougher start/idle/power delivery at higher revs
– a few random misfires (without a check engine light, observable with scan on a OBD2 reader and app)
A few technical problems to look out for:
– rusty bolts for heat shield (lube is your friend, don’t over torque), heat shield has to be angled the right way to slip out
– electrical connector harness clip can break, be careful/gentle with both the clip and the slide-out lock (red)
– O2 sensor can be seized, access is tight even with the right tool (see video for potential solution), remember to apply anti-seize to the threads on replacement and not to over-tighten.
Don’t forget to reset your ECU (e.g. disconnect your battery for ~1/2 hr.) to let the car relearn the new sensor’s characteristics.
Good luck!

Where did you buy the sensor?
So do I have to do it with only one hand or can I use both?
Also I can’t fine the plug for the secondary o2 sensor at the bottom I tried following the wire with my hand but couldn’t get my hand far back enough
Hey I kno I’m a bit late but would you happen to render the code that caused the faulty mine was p0137 bank one
Hello, first of all gret videotutorial. I was just wondering why you changed your O2 Sensor? Did the car show engine code or not? I am having problem with my car. It shows p0101. I read somewhere that bad O2 sensor can cause p0101. Is this true? Thanks in advance for answering and best regards to you.
Hello
I'm interested version sensor Bosch (0258 006 — , catalog number ) ?
Thank you
These cars are easy to work on?
what was the code that came up for this
That heat shield for the turbo has a metal clip in the back. The easiest way to get it off is to push it towards the heatshield a little, and yank it up pretty forcefully. It took me a while to get mine off the first time.
It’s that the 02 Bank 4 Sensor 4? I’m having this problem on my saab 2004
Thanks for the upload! Sadly, mine needs the downstream one replaced.. I'll keep looking for a video..
Did you read my mind?! I've been looking for a video on how to do this for a few days now! Thanks mate. Nice one.
"Ahhhh ya!" Lol
Good video thanks!
