Hey guys,

I finally installed my WS Y-pipe a week and half ago, and a couple of days ago my engine light came on. The ECU gave me codes 0308 and 1001, which are a closed loop control problem and a Front Left Htd 02 sensor heater problem respectively.... I'm thinking that if I fix the o2 sensor heater problem, it will automatically take care of the closed loop problem as well.

Well the question is... what is an 02 sensor heater? Where do I find the FRONT LEFT HTD 02 sensor heater and how do I replace it? Is it really important to replace?

I went to the detailed ECU code page http://forums.maxima.org/showthread.php?threadid=235667
to see exactly how I would go fixing the problem, but it had a link where the 1001 code is and I was not given access to view it. Maybe someone can tell me what it says.

please help
