hey guys, got a problem....i installed the o2 simulator about 2 weeks, soldered and everything, works fine, the lights blinking....but as im down to my last 1/4 of gas the SES light comes on.....ok so i filled up and reset the ECU, then after driving 10 miles on the new tank, SES comes back on again....same thing happened again this week.....the simulator works for about a week and stops after that, i cleaned the rear o2 sensor last week too.....what should i do??.....time for a new O2 sensor??

 

search for the mechanical o2 sensor fix

 

did you try to pull the code and see what it is? you can't assume it is the O2 sensor when the engine light come on.

 

already got the mechanical fix, doesnt work for me

ya, that's wat im thinking it might be something else, im gonna check it out the next time it throws the code......could it happen because of the not so fresh, maybe dirty fuel thats left at the 1/4 tank mark
