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.
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.
I didn’t have a code, just thought I’d do this for maintenance given the symptoms I had (fuel economy and not as smooth power). I think it was probably more to do with plugs and coils but no big deal in the end to do this anyway.
Probably need to replace the sensor? I thought mine was running "fine" but it was a bit smoother afterwards. Not sure about your limited speed but I don't drive that fast anyway most of the time!
@@LightandLensPhoto there's a place where I live that if you don't drive 80 MPH they'll run you off the road, and there are no cops around. so all my other Saabs always performed their best from 70-130 MPH
@@LightandLensPhoto here's what's crazy, I bought new injectors, plugs O2 sensors, the relay, and an air filter...I ordered the dress-up kit,7 polished screws, and an oil cap with the Saab dragon polished. (I'm going to put in a cold air intake)so I loosened the screws for the air filter box all the way, ran my scanner, and got a P1312 code..and the P0135 was gone? My brother gave me an expensive Tech 2 type scanner where I could pick the make and model..and again ..just the P1312 code. im going to change the coils and plugs ..but weird...would that little amount of extra air buy making the air filter that loose do that?
Or if you mean the actual location of the o2 sensor? That’s farther down the cat convertor. You have to get to it from underneath, removing some of the routing for the intake. View from underneath should looks like this. saabwisonline.com/images/9440/img-f2/f254r215.jpg
I don't think the filters do themselves but if you get rid of the air box to do a cold air intake it's only for looks and a bit more turbo noise. It's already a cold air intake, it goes from the air box eventually to the front grill. Unless you open up the front wheel well, some have done that but then you risk getting a splash into the air.
@@LightandLensPhoto I had one of the last 900s that ended up on the 9-3 Viggen line, and they couldn't get it to run, the dealership sold it to me for 2 grand no questions asked, they said the car had been shipped to 3 other dealers, and it looked one of a kind, it beat everything from 70-140 ,it overheated and just made it to the shop when the guy put the thermostat in backward and ran it till the plastic in the radiator blew a hole, all the fluid came out and it still ran in 95-degree weather
@@LightandLensPhoto im going to do a cold air intake, but make a custom air hole that's large in the grill and goes to the filter, that will be the waterproofed kind.and try to bring air to it from everywhere, and a tuning chip
Sorry to hear! I'll probably have to do that at some point soon too. Why do you think you have to replace it though? Not sure it even matters except for emissions maybe?
@@LightandLensPhoto yeah.. I'm getting engine light and a code which is "downstream O2 sensor heater circuit failure", I've been told this is now an MOT (UK government test) failure. :-(
@@michaelrmonk If you want a simple solution... swap the O2 sensor harnesses, then switch out the defective "upstream" sensor. Much easier to access than the downstream one. Edit: that won't work long-term now that I think about it. Just thought it might help with passing your MOT.
@@LightandLensPhoto well.. you're sort of on the right track there.. in that I had read that it's possible to wire in a high wattage 10ohm resister to make the ECU think it's ok. That might be the simplest solution...
@@michaelrmonk That's not a bad idea. If you have access to a code scanner and app, you might be able to read what the voltage is (e.g. too high or too low) to figure out what resistance you need to make it happy.
Many thanks and looking forward to the O2-2sensor demo
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.

Yup, realized that afterward. Tight fit otherwise. Also, one-handed for the video...
Thank you for the video berry helpful👍
thanksssssss alot
"Ahhhh ya!" Lol
Good video thanks!
2:37 ahh yeahhh

No codes, just worse fuel economy. Ended up it was more likely (or combination of) old coil packs and spark plugs.
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

I have a 2005 Saab ARC ,and i have 2 P0135 codes? and the car drives fine ,but wont go over 90 MPH?

and where I live has the most Saabs in the world in one place...all low mile 86- and going for the price of a car part.
🤷♂️😂😮
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
Do you mean the harness where it plugs into the ecu? It’s right next to the upstream sensor plug. saabwisonline.com/images/9440/img-f2/f254r211.jpg

It’s that the 02 Bank 4 Sensor 4? I’m having this problem on my saab 2004
Not sure what your sensor problem is, but on my scanner it's called bank 1 sensor 1. There should only be two.
Ok thank you.
Do K&N filters mess up the car?
I don't think the filters do themselves but if you get rid of the air box to do a cold air intake it's only for looks and a bit more turbo noise. It's already a cold air intake, it goes from the air box eventually to the front grill. Unless you open up the front wheel well, some have done that but then you risk getting a splash into the air.

ive spent most my time in the 120 MPH area in my Saabs
Where did you buy the sensor?
I think I got it from Rock Auto
These cars are easy to work on?
I don't know... Define easy? There are quirks for sure.
Its not easy. But it's not Difficult
what was the code that came up for this
No code came up, just my fuel economy was getting much worse.
Thanks for the upload! Sadly, mine needs the downstream one replaced.. I'll keep looking for a video..

So do I have to do it with only one hand or can I use both?
