Vehicle make/model = olds aurora
Year = 2001
Mileage = 85400
Engine size = 6
dash lights = check engine
codes = yes po385 & po410
work done prior = none
work done to repair = none
tip/donation yes
tech = jk
question = Po410 can on first then po385 >>>410 came on first >> the
light would go out for a short time but would come back on>> I have been
trying to investigate the problem>> the p0385 started up next>> the
tack started go nuts>>\ please send me information on how to fix .I do
antique cars but this new cars are something else.
Please delail steps .. location and parts needed
Iknow that po419 involves the secondary air pump system and the po385
involves crankshaft position sensor b circuit. I don't know if there is
a connection or two difference problem.
Please instruct me how to fix

Thank you for the tip/donation.
These codes are probably not related.
p0410- most likely cause is the AIR pump has failed and needs to be replaced. GM
has a kit with new pump and hose- part # 19515548. Instructions included with kit.
But, the AIR diverter valves can also cause this problem. Check the AIR fuse in the
underhood fuse block fisrt. If it is blown, then the problem is the pump, and possibly
the harness is melted. If fuse is not blown, then one of the diverter valves may be
bad. Those can be checked with a vacuum pump. The AIR pump is under the car in
front of the dr. side wheel. Access from underneath.
p0385 is the crank position sensor. Also from under the car. A little tough to get to.
Will need a socket, extension, and swivel to remove. Quite hard on the wrist.
Removal of the starter will make it easier, but not absolutely necessary. After
replacing the crank sensor, you will need to have a "crankshaft variance re-learn"
procedure done, or the same code will come back. This needs to be done with a
scanner.
I will gather some pics to help you with these repairs and send them
