PCM 1416 C Code
Anybody know what would cause a PCM 1416 code? I replaced my intake manifold with a LS6 manifold, and thought that I got the AC hose in the back hooked up right, cause I think it's blowing cold air.

Re: PCM 1416 C Code (baroni)
Baroni,
The 1416 is defined as AIR System bank 2-B. Here's the whole story
The Air System Bank 2-B is;
An AIR pump is used on this vehicle in order to lower the 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.
So it looks like you have an inoperative bank.

THRAP 42,
Inoperative bank means what? This is a test involving the AIR pump and O-2 sensors. If the pump is bad, both codes would throw. If an O-2 is bad, other codes would be thrown. What other parts / systems are involved? Been getting this 1416 code myself lately.

Walt,
Sorry but can't answer the question - have the capability to tell you what the code means, but not technically competent to explain what the problem could be - sorry.
Later,
C4C5Specialist would be your best bet.
