HELP, code P1419?
HELP, code P1419? Crusing down the road and the SES light popped up, got it scanned and it showed 2 codes both were = P1419 - Split Air #2 Circuit Malfunction. Auto Zone could not tell me waht exactly it was. Does anyone here know what this is? Please help people.

My GM code list doesn't show this,only 1415 and 1416,both relate to the Air pump relationship to the o2 sensors..Are you sure thats the codes?I'll post the the description of 1415 and 1416 anyways.just incase.
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.

I'd have it read again, only other code I see thats close is P0418 - also relates to the secondary air system. If the lights still on and you live near Blanding/I295 I can read it with Predator.
yeah i know that the book doesn't show the obd2 codes that are higher #'s but autozone gave me a print out showing the code. I am positive its a P1419 I was there when the scan was done and i saw the scanners screen
