2013 Chevy siverado 5.3 engine LTZ

Question

It puts out codes of p0172 And p0175

Answer 1

Hi there

Bank 1 is the driver side of the engine. If the sensor is causing the issue it would be the first O2 sensor on that side of the engine. Since you have codes for both sides of the engine, I would suspect an issue with the fuel pressure or mass air flow sensor.
