 Subject: trouble codes p0136, p0031, p0051

I have 2001 quad 5.9 4x4, about a week ago i noticed the engine light was on, i did the key on, key off thing and got three codes p0136, p0031, p0051, i reset the computer and the p0136 code comes almost immediately, the other two come after a few miles of driving. i looked around (allpar, obdii) and found these are broken or shorted sensor codes. the p0136 code is bank 1 sensor 2, which i am assuming is the driver side sensor after the pre cat. since i haven't had a code for the passenger side after the pre cat, i swapped the two and reset the computer to try and get a code for the bank 2 sensor 2, but i still get the p0136 code. there are four sensors in all one before the pre cat and one after the pre cat on both sides, and nothing on the catalytic converter itself. is there something that all these sensors have in common? i have had the exhaust done, a B&G flash, araid intake, 180 thermostat, accel coil, autolight plugs,IAT sensor to the intake tube, and all the other tips and tricks i have read about here, so i am not itching to take to a dealer so they can tell me it's my fault, but haven't done anything in the last year or so. i haven't noticed a difference in mileage or performance, but that engine light is driving me nuts. ANY help would be appreciated
thanks in advance
