My problem started when I had to jump the car one day after work, it was hard to jump the car for some reason to begin with but after a few attempts we got it running. As I was driving the check engine light came on and was blinking but the car appeared to be running smoothly so I figured it would go away at one point.

Nope, till this day the cars check engine light is still on, and it blinks when I go past 40 mph, I got it checked at auto zone and the code came back as p0030 which didnt really tell me what was really wrong with it, more like what could be wrong with it.

The new problem that i'm noticing is that I'm getting lower gas mileage and the rpms seems to be running a bit high, they fluctuate actually.

My final problem is that my break light wont work at all even after replacing the bulb the mid break light on the back car window works fine but the break light don't.

Any ideas ?

 

hey, I just bought a 2001 S80 2.9 twin turbo charged... I also got the engine light on.... but it goes away after driving for a bit... any ideas???

 

P0030 ECM-2810 Front heated oxygen sensor (HO2S), preheating

Signal missing. Permanent fault

 

Recommend starting a new thread and posting the OBD code...

 

Would you say thats causing most of my problems?

 

I'd start there for sure...
