o2 sensor

Hello everyone. I'm new to the forum and I've tried to search for this relating issue without any success, so i'm sorry if this is repetitive. I have a 2005 9-3 Aero Convertible (aprox. 96,000 miles), and I noticed about a week ago that it has an oil leak (which has likely been there for...

Hello All, I am at my wits end with Saab and really need some help. Bought the car new in 2003 and it has 95,000 miles. Started spewing white smoke and after reading everything I could find I did a compression test which was ok and then replaced my turbo. Did the work myself and when I was done...

I need help with my 1985 900 turbo. the car sat for a while and when I took it out for the first time it was about a 20 minute drive to work. it drove fine there and back. the next day I was driving and after about 15 minutes the car stated to violently hesitate if I try to go over about 2500...

Hi: I'm looking to buy the bracket that holds the two O2 sensors and the CPS sensor wiring connectors on the 2002 and on 9-5. It mounts near the thermostat housing. My car is missing this part and the connectors are just loose in the engine bay. I can't find a part number for this thing...

2007 Saab 9-5 2.3T 4dr SportCombi has been running erratic, 1st time in 5 years. With only 129,000 miles my car will not always restart after driving it about 30 miles and then shutting it off for about 20 minutes and it will repeatedly misfire when I hit any speed above 60 mph. The mechanic...

The car was running poorly recently, especially since a week ago, and throwing intermittent P0300 and P1181. I thought I'd start with the cheapest fix (Vacuum). When I removed the engine cover to inspect them, I noticed that my PCV is completely banjaxed - see this thread. My mechanic...

Hello fellow Saabers! I'm a proud future owner of a hand-me-down 2003 Saab 9-3 Linear with over 225K Miles! I've been browsing the forums for a while and couldn't seem to find my specific problem, and I've visited all free medians for advice, which is only a couple auto zones which don't know...

Hi everyone, I am trying to get my check engine light off on my 2003 Saab 9-3 Linear. I am down to 1 Code that needs to be resolved. Autozone scanned the computer and it came up with Code P0037 heated Oxygen Sensor Heater Control Circuit Lower Bank 1 Sensor 2. This is obviously an o2 sensor...

Hi there, I want to replace the O2 sensor on my 1984 Saab 900s (not a turbo) and just want to confirm that there's only one. I'm not a mechanic but I do have ramps and it sounds like a relatively simple thing to do. I already figured out how to reset the button that set off the EXH light in...

I'm wondering if anyone has any insight to this issue. My 2003 9-5 Arc wagon started throwing a code for the front oxygen sensor shortly after I bought it. I installed a Bosch replacement and the code did not go away. Even after resetting the computer and clearing the codes, the check engine...

Hello all, I have a puzzle for you. I have a 1999, 9-5, 2.3T, Wagon, and since buying it back in June I've learned more than I ever thought I'd want to about it. Since I spent my hard earned cash on the thing I've had to replace the big end and main bearings, the PCV system, the heater bypass...

I have a 2002 saab 9-5 linear sedan 2.3t. I have codes for cat inefficiency and o2 sensor low. When I went to look at the o2 sensors I have one right after the turbo that is wired up, then a pre cat, then another o2 sensor that is wired up, then a cat, then another o2 sensor that has the wires...

I replaced the O2 sensor, but these two codes still come up. Any help out there? Thanks... P.S. Those codes translate to: P0141 O2 sensor heater circuit malfunction bank 1 sensor 2 P0135 O2 sensor heater circuit bank 1 sensor 1

So I have been getting a CEL. O2 sensor High Voltage. Some of the symptoms i have noticed is a drastic plumet in my fuel economy. A dismal 15mpg. Will replacing the O2 sensor solve my problems or is there another underlying cause. Another thing. Is replacing the O2 sensor a simple thing to...

Hello everyone, Just want to post my fix for a OBD code P1141 on my 2000 Saab 9-3 with B205. Had Check Engine Light on and was told at Autozone "Heater circuit current being too low on post cat sensor". After reading endless posts on this and some other web sites it turned out to be a wiring to...

Are 9-5s equipped with wideband O2 sensors from the factory? If so, is it possible to tap into the sensors harness for a gauge without interfering with the readouts being sent to the T7?

I started my 2001 Saab 9-5 V6 this morning and it turns out it has a very loud knocking/sloshing sound. I had things to do so I drove it anyway. It has not decreased my performance any, which is surprising. I have a bad O2 sensor but that shouldn't cause a knock as far as I know. :x Any Ideas?

I have a '99 9-5 with a 2.3 and the CEL is on. I have tried clearing the codes and the light returns. I hooked it up to an OBDII and got a P1141 code, which I believe is a heater circuit failure on the #2 O2 sensor. What I'm wondering is how I would go about diagnosing the problem further and...

Hello - I'm new to this forum and have a quick question about my O2 sensor. I don't know which one is faulty (yet) but I am considering buying an aftermarket O2 sensor for about $35 and plugging it in. My CEL came on and the local garage ran a diagnostic for $75 and found that the O2 sensor...

Hey i need some advice, im used to the T5 engine and i have a 1999 viggen now. I installed a jsp downpipe and a Forge splitter which is a hybrid BPV. It allows either 70% atmospheric and 30% recirc, or vice versa or full recirc or full atmospheric. Well i installed the dp and i hear a buzzing...
