P1072 bank1 fuel system too heavy
no engine option stated. displacement and cyl. count I6 , V6, I4?
are you asking all ways 1072 can happen?
all this is in the FSM. read it.
but here is the bar stool answer.
warring do not use non jeep P1 codes P1 is Jeep only !!!!!
do not let autozoned, tell you what the code means, they are clerks.
and not trained. (if they did it, you didnt say what tool pulled the code)
i can tell you transposed the 1 and 0, there is no 1072.
so its actually the very common and unversal EPA, P0172.
billions of posts on that www.
P0 means federal codes. a standard
so we look that up, , and is the error for fuel time , too rich.
so i can see you looked it up and got that right but posted wrong dtc.
i can go further but not with no engine options stated. .......
the I4, I6 and V6 are all different beasts.
but can say (pure physics and EFI knowledge)
1: the O2 is bad, bank 1 sensor one,Front, or if v6 , bank1, sensor one the bank that is #1 cylinder , front is bad
2: engine is running way too rich for 50 reasons, (tests find it)
other sensors bad, mech, eng. issues, leaking injectors, endless....ask
3: exhaust leaks near Sensor 1.
there are the top 3.
what tech might do, is replace the 02 , on suspension.
its older than 100k miles so , bingo its listed in the service sched.
he goes to change it and see the bank header cracked, dang.
example 2, near endless story , ask.....
i run the scan tool and look at all sensor data.
see what is right and wrong.
there are some tricks too, to force lean and see if B1S1 wakes up.
