Code p2197 I have a 2005 Mazda mpv 3.0L engine V6. I add a o2 sensor code bank 2 sensor 1stuck. I replace the sensor 1 bank 2 before the converter a week ago , know I'm gating a new code p2197 o2 LF stuck for bank 1 sensor 1 is stuck. Can anyone tell me what do I need to do? Thank

My strong guess without looking at it would be a cracked exhaust manifold, when it gets hot the metal expands an it doesn't leak.

Possible problem is carbon build up in intake runners..remove top intake and clean runners..

SOURCE: Where is the bank 2 o2 sensor located on a 2004

bank 2 is the cylinder in the front of the engine compartment near the radiator, the O2 is either in the exhaust manifold of the bank or in the exhaust pipe off the manifold, round about the size of a jumbo magic marker, you need a special O2 sensor socket to remove it in some cases, if it is in the open then a 7/8 open end wrench will work.

bank 1 is the bank of cylinders closest to the firewall. the sensor will be located along the exhuast from that side after the catylitic converter
