Where is Bank 1 Catalytic Converter on 2010 Buick Enclave?
We have a check engine light on. The reading
states it is the Bank 1 Catalytic Converter. Where
will it be located? Also, our battery was cranking
real low around 440, the car calls for a 730 cca
battery. Could the poor start up cause the light to
come on and show the catalytic converter code. I
ask, because the light came on and after a few
trips around town, it went off. Then this morning
after setting for awhile and being very cold out, the
light came on again. Thank you.
