can an exaust leak fault out my o2 scensor
i ran my 2003 cts with
an exhaust leak for a
while . and then my
error codes read p0036
and p0141 . i shut off
check engine light and
as soon as i turn car of
and back on the light
comes back with same
two codes. i got new
flex pipe fixed leak but
light will not go off still
is most likely the bank
scensor 2? it says
heater low side open
circuit.and heater
circuit malfuntion .
