Hello,

my 2001 95 recently started hesitating, especially when cold and the engine light came on. I read the code using an OBDII reader and got oxygen sensor 1. Replaced the sensor with a Bosch and reset the light. A couple of days later, the problem came back.

Has anybody run into this before? Are there other known problems that might trick the computer and set the O2 sensor off, or possibly something that could be destroying the O2 sensor? Is it possible that the Bosch sensors are not good for this car? Any other thoughts?

Thank you!

i had the same thing. i got p0133 and replaced the front oxygen sensor. the light came back on, and then i had it cleared again. i guess that the t7 had the criteria satisfied and the light remained off. hope everything works out for u.

Thanks for the reply.

The code I got was P0134. I've reset the sensor twice since the front O2 was replaced, but the light continues to turn on and the car is still hesitating. So, there is still something wrong ... I'm just not sure if its really the O2 sensor or something else setting it off.

Appreciate your help.

Have you used an OE sensor or a pattern part? I recall people having CEL problems when using "equivalent" sensors.

Its a Bosch sensor purchased from thesaabsite.com. I assume its a non OEM replacement part for this model. Is this the part that people have had problems with? I would get a Saab part if I knew that it would solve the problem. But the parts aren't cheap of course, so I don't want to through good money after bad if there is another problem.Thanks for your help.

did you buy the one that was a direct replacement or one that required wire splicing? the one that i bought required splicing, and i havent had a lick of trouble from it. the light went away after about a week.

It did not require splicing. The store that I ordered from had only one option for this model vehicle.

m114: Did you ever resolve this issue.

I just got a P0134 code . This is 1 day after replaceing my spark plugs. Any ideas would be appreciated.THanks

The problem still persists. The car hesitates and the engine lite turns on when the car is started cold. Still reading P0134. When the car warms up, it runs fine and if restarted when warm, the engine light turns off.

I'm just not sure that the O2 sensor is the root problem, so I haven't tried replacing again.
