Where is O2 oxygen sensor Bank 1 sensor 2 on Pontiac Atzec.


Hi.


The sensor two is the one located after the catalytic converter. While sensor one is always the O2 sensor located on the engine side.


Bankone refer to the sensor located in line with cylinder number one (theone that is sparking first i order). The firing order on Pontiac Atzec is as follows:

on the 4 Cylinder engine : 1-3-4-2

on the 6 Cylider version : 1-6-5-4-3-2,

This means that the cylindernumber one is located on the left hand side.

See the diagram below explaining how to access sensor two. The protective cover is not present on all models:

Note: before replacing the O2 sensor (lambda sensor) ensure that the problem is not wiring or connector.
