Code Help!!!!
ok so i just pulled up a couple codes of my car becuase its cel light was on this is that i got..
P1151 Lack of H02S-21 switch, sensor indicates lean and P1131 lack of H02s-11 switch, sensor indicates lean...
I havn't touched my O2 sensors all i have done is hit them as with my bolts with some PB blaster to make them easy to get off... what could be causing this?? and for both of them to read this?? what gives??

Check the harness for the 02 sensor, make sure there's no fraying or cracking at the sensor and make sure the harness connection is clean (use dielectric grease on it once you clean it out). If that doesn't do anything, then I'd move on to replacing the sensor (use Ford original)

I would also do a close look throughout the motor for cracked or loose hoses / connections. Could be a vacuum leak also in there somewhere. MAF plugged in?
I use WD40 and spray around suspect hoses with motor running, if idle changes when you spray a spot, you have a leak.
However, a lean condition usually spits out a 02 sensor lean reading, not a low voltage reading. I still think there's a sensor problem.
