Re: Low Voltage Bank 2 Code

I believe a Low Voltage Bank 2 issue has to do with an O2 sensor.. is the code P0151?

I know that this is not Oxygen Sensor going bad but rather power supply to it. I failed to note the code.
Bad Oxygen sensor codes are 11xx numbers.

Code P1119 perhaps.. (Short to Ground) Check ground wires. Make sure they are clean.

Perhaps Bacardi 151?

Re: Low Voltage Bank 2 Code

i would either recommend you change the O2 sensor, or simply unscrew it and screw in an airline sized mini-bottle of sky vodka in its place.... should fix everything up!

o2 sensor provides the current (0v to 1v). the only current that it gets is only for preheating.
to fix the problem normaly is to change it. doesn't return enoug current.
