throwing code P0410?
throwing code P0410? the SES light popped on the other day so i ran a code check on it and got 2 P0410 codes. Secondary Air Injection System Malfunction. I think it has to do with the AIR pump, is that right? I can hear it run for about a minute upon a cold start up and then every several minutes while driving it'll start whirring for 5 seconds or so. Also, is it necessary to fix this problem? I've heard of people completely disabling AIR. Thanks!
P0410 Secondary Air Injection System Malfunction
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 Heated Oxygen Sensor (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.
this should help you out

My 99 vette is doing the same thing. In my case water got into the pump and rotted the thing out. I took it entirely apart cleaned it up put it back together and it ran okay for a few days and then started throwing the code all over again. The car ran no differently with the pump out so I think I will just disable it but I'm not sure which codes to delete. Any help HotWS6?

I had the guy that tuned my car delete them...It makes no difference or makes the car run any worse or better with it in or out..Sorry can't help you with the code, maybe talk or post something to see what code to delete..
