went to autozone to see what made the ses light come on and it came back p0410. he said it might be air system, or to check for open circuits. does this have anything to do with the o2 sensors also? i had lt's, catted y, new wires and plugs installed resently and my y pipe is banging like a sob. any help would be great.
thanks, jeff

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.

thanks for the info. where can you find these descriptions for the codes? so i guess i will have to get new o2 sensors or get them deleted

I just had this code last week, it turned out to be the check valves.

Took it to the dealer thinking that it was the air pump which is covered under my extended warranty. Turned out to be the two check valves on top of the exhaust manifolds <they got replaced> and a distribution module under the driver side cowl by #7 coil pack. As luck would have it.....all that crap wasn't covered

it says in your sig that you have LT's are you even sure that your AIR pump is hooked up?
