Hello,

Here are the code def's I have and have found.

P1151 O2 Sensor Heater Circuit Signal Intermittent (Bank 2 Sensor 1)

P1151 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2

P1151 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2

So, I would change the O2 Sensor in the Exhaust Manifold on the Drivers Side, which would be Bank 2 sensor 1 or the Bank 2 Upstream Sensor.
