I don't wish too hijack the thread but I have also been receiving the 1416 Code on my 98 Camaro ss. I just replaced the plugs and wires, no SES light. I then replaced the exhaust with a Magnaflow exhaust system. I then received the SES light. I replaced both check valves and cleared the error code. Yet the SES comes back. Is there another direction I should be taking ? The car is stock except for the above enhancements. I live in South Jersey the car has 71.000 miles.

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.

2xLS1 Thanks for the quick reply, I appreciate the information. I will recheck the codes tomorrow to make sure that I am only receiving one code. I have read the forums threads and it seems that the majority of issues have been solved by replacing the air check valve. I will continue on and see what happens. I also appreciate this forum for everyone who gives great feedback.
