ses popped on a few days ago, got it scanned today and heres what it gave me

P0155 - 02 Sensor Heater Circuit Malfunction
(Bank 2 Sensor 1)

P0751 - Shift Solenoid A CKT Performance Or Stuck Off

the problem is that i just replaced the ******* O2 sensors on the front like 2 weeks ago, after having them replaced 6 months ago! WTF is going on here? my driver side O2 shorted out 6 months ago which shut down my left bank and costed me 600 bucks to figure out what the h3ll was wrong after towing to three diff shops.

why does this side keep going out? even though its wrapped with electrical tape as far up as i can get... and why is the heater circuit malfunctioning?

o ya, the shift solenoid has always been thrown everytime ive checked for codes. i figure cause ive had my pcm dyno tuned, with the tranny tuned as well. Can anyone help me to end this?

FYI all 4 of these sensors are the same, so you can swap them around....
