Ok i know the KS usually doesnt throw a CEL, but I hooked it up to a scan tool and in the pending codes I got the PO325 KS 1 Circuit Malfunction....
Im assuming I need to get a new KS right?

But I also had a PO155 02 sensor b2 s1 Heater circuit malfunction. You know this means the heater isnt working, so I may be entering in and out of closed loop while driving depending on Temps... I was just wondering if any of you think that this in and out of closed loop is also setting the KS....

Cause isnt the KS (is bad) code a PO334? Or am I wrong

Also, its 02 b1 s1 the o2 closest to the passenger side on the y-pipe (before the cat)?

I assume I should just replace both right

Thanks so much,
Jeff
