P0150 vs. P0141 ??
Last month my CEL came on. I pulled a code 0150. I had my indy replace the appropriate sensor. Last night, CEL again. Code 0141. Is this a different sensor?

ODBII codes
P0150 O2 sensor passenger side, upstream closest to header.
P0141 O2 sensor driver side, downstream closest to cat.
What did your Indy shop replace?

It appears that the P0150 code is related the "left, front" O2 sensor. However, a dirty or worn MAF could potentially throw the same code.
Code P0141 is related to "right, rear" O2 sensor. So did the Indy replace only 1 sensor or 2? There are 4 O2 sensors total. Most on the forum suggest to replace all 4 @ 100K miles.
I recently threw codes P0174 and P0171. I replaced my MAF, after cleaning proved ineffective. Still throwing the codes, I replaced both front O2 sensors. Been CEL free for the last 5K miles. The car has just turned 95K.
Good luck!

Update: Busy with work, and four months later, I finally got around to addressing my Error Code P0141 (rear/right oxygen sensor). As it stood, my indy wanted $250 parts/labor. But, after a bit of research, it became a DIY project. The two front sensors can be a PITA, but the two rear oxygen sensors is an easy no brainer DIY. I purchased the O2 sensor from www.pelicanparts.com for $118.00; placed the beast on ramps; crawled under via front end which placed me dead center of both rear sensors; released old right sensor from the transmission pan clip; unplugged the old sensor; released old right sensor from the exhaust pipe (used a 7/8 box/open wrench); and then the reverse. Saved over $125, and spent $10 of it on a six pack of Stella Artois. Me happy.
