Wow! Its been a long time since Ive been on here. Ok I did a search. Couldnt find what I was lookin for. So I will ask. I bought a 2002 focus 2.0 engine. I have fixed a few problems already by searching on here. Great help!!! But anyway now Im wondering if a collapsed pcv valve hose would also cause the cel light to come on and throw a P0141 code which is the O2 sensor. Just curious is all. Thanks for any help.

Ok just curious is all. Went and scanned it again couldnt remember exactly what is said. The code was P0141 H02S12 heater circut fault. Which sensor is that? The farthest rear one right?

2006 focus wiring diagram shows 3 o2 sensors
P0141 is for heater fault HO2s12 would be middle one
