I'm setting off code's P0137 and P0157= circuit low voltage Bank 1 Sensor 2 and circuit low voltage Bank 2 Sensor 2. Does anybody know if this is caused from to much fuel under WOT as this is when it usually set's the code? Thanks

 

Bad rear o2s. Most likely from the pressurized exhaust track or from being too rich all the time (but it would be waaay to rich -- black smoke and a missing feel)

 

What would be the solution??

 

anybody?

 

You can have allen just turn off the rear o2s or replace them with new sensors. Personally, I'd turn 'em off as they are just going to die again.

 

99% of the time its just the sensor itself. Take a peak under there and make sure the wire is not melted some where. This is a lean condintion, If post cat 02's stay under 400mv (dont quote me) +or- during PE for 5 sec or more you will though this code. This is just a post cat monitor anything major should show upstream if this were true. So most likely its just the 02 sensor or its shorted out somewhere.
