CEL code P1151?
I just pulled the code from my dual exhaust 4.6 ('95 Tbird) and the code P1151 came up. I just want to confirm what I think that this means. If I understand what I am reading, this is a fault with the drivers side, upstream, O2 sensor. It is not registering any voltage (left bank rich). This could either be a bad 02 sensor, or the wiring to the 02 sensor.
Is that a correct diagnoses? Am I interpreting the code properly? As it is only the left bank, are there any other conditions that could cause this code to appear?
Thanks in advance.

It's typically a bad sensor that causes that. The sensor is not switching as it sees the lean/rich pulses of exhaust gas,and that causes the code to be set after the threshold for time has been met. And yes,that's the driver's side primary o2 sensor.
