Question

cual es el sensor bank 1 o en realidad donde esta ubicado o que es en realidad el fallo

Answer 1

Hi there,

This code is normally caused by low fuel pump pressure, the front O2 sensor or a faulty mass air flow sensor.

I have also seen this code caused by intake manifold vacuum leaks and catalytic converters being blocked and forcing exhaust back up into the engine.
