Check Engine- DTC PO410
Check Engine light is coming on
I'm getting a PO410 DTC with the Auto Tap.
I'm showing that the code has been set ? 5 times
2 set right from the begining when the car was new
as early as 12 - 14 miles on the car. (freeze Frame)
3 of them say nothing about freeze frame
So........
what should be done about this ??
edit....after looking at the dtc's again, I should add that all the
PO410's have the "H" (history) after them
Thanks for you time,
Michael

"CIRCUIT DESCRIPTION
An AIR pump is used on this vehicle to lower tail pipe emissions on start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump. The PCM monitors the HO2S voltages to diagnose the AIR system.
During the AIR test, the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.
If the PCM determines that the HO2S voltages for both banks did not respond as expected during the tests, DTC P0410 sets. If only one sensor responded, the PCM sets either a DTC P1415 or P1416 to indicate on which bank the AIR system is inoperative."

Most of the time the AIR Check valves stick shut not allowing air to pass. My 02 Z06 had the same problem. Took it to the dealer under warranty and they changed both check valves. Problem solved.
There are also other things that could be the issue. The air system derviter valve is vacuum controled and the rubber piping that connects the pump to the rest of the system could be loose or damaged.
The pump is under the drivers side head light; Here is a picture of the back of it.
I have other pictures of it. PM me your e-mail address if you want them.
