P0410-Air Pump
I have a code P0410
2002 C5 LS1
Heres what I have:
I've cleaned both air valves. They appear to be O.K.I used carb cleaner and air as recommended by others.
The air pump comes on when the engine is cold and blows hard. After a few minutes, the force decreases and completely stops.
Is this normal?
I would assume it should blow all the time. Am I correct?
Any help you gurus can give will be appreciated.
thanks in advance!

Car is 100% stock 75000 miles. I'm the third owner, I don't abuse it, I cruise in it.
I bought the car with 67000 miles on it.
First engine light since I bought it was 1 month ago.
Originally had a 1415 code. Cleared it, 2 weeks later had P0410. Had a P0141 code once, but has not reoccured.
Niether has the 1415 code.
The P0410 code keeps coming.
Any help will be appreciated

One last question.
As I stated, the pump comes on when the engine is cold and first started for the day.
However, the pump does not come on everytime I start it .
Should'nt it come on every time I start it?
Thanks for your patience!

If you have strong air flow from the pump(downstream of the shutoff valve), then that would suggest two possibilities....both falling in the remote category:
1) Both check valves are stuck closed
2) Both O2 sensors are not responding
What is the history here? New problem? Stock exhaust or headers? How many miles on the car? Are you the original owner?
