hi today i was driving home and about 10 minutes from home my check engine light blinked for abpout 2 seconds and then went off and stayed off.. so when i got home i checked with my code reader and i got code (44)..

in the book of codes (code 4) states this

lean exhaust indication - oxygen sensor voltage stays low after one or two minutes of engine run. (left sensor or dual sensor engines.)

and thats all it says... can anyone tell me what my actual problem could be? do i need a new o2 sensor? thanks john

44 - System Lean

i got that.. i no what it means but how do i fix my problem....? thanks

Are you the one that was complaining of bad mileage? I think a dying O2 sensor was suggested as one of the possible causes for that.

could the o2 sensor be the cause of both my problems.. ? poor gas millage and code 44? thanks alot for all your help.. i picked up a new o2 sensor and gas filter at autozone..

Here is another contributing factor to poor fuel mileage

does'nt anybody no whats wrong

More than likely its your oxygen sensor causing this, also check for vacuum leaks..

I would get that code randomly in my old sse once i put in a new o2 it was fine...

Agreed, sounds like a classic O2 sensor failure.

ok so today i put a new o2 sensor and about 8 hours later i am still getting the same code 44..... do i have to unplug the battery for a while to reset the computer or something..? thanks john
