My car is throwing code P1415. :( There is a history of this code popping up and it is current. Usually if I clear it, then it won't come up for a week or two. I know it's air system bank 1 by looking it up in the tech section, but what exactly is it and is it something I can fix myself? :confused:

Thanks :chevy

 

DTC P1415 or P1416
Circuit Description
An AIR pump is used on this vehicle to lower tail pipe emissions on start-up. The powertrain control module (PCM) supplies a ground to the AIR pump relay, which energizes the AIR pump.

The PCM monitors the heated oxygen (HO2S) sensor voltages in order 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 the 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 1 sensor responded, the PCM sets either a DTC P1415 or P1416 in order to indicate on which bank the AIR system is inoperative.

Conditions for Running the DTC
DTCs P0101-P0103, P0107, P0108, P0112, P0113, P0117, P0118, P0125, P0171-P0175, P0200, P0300, P0335, P0336, P0351-P0358, P0440, P0442, P0443, P0446, P0449, P1120, P1220, P1221, P1258, P1441, and the HO2S DTCs are not set.
The engine is running for more than 30 seconds.
The maximum air flow is 22 g/s.
The air/fuel ratio is 13.125:1
The engine load is less than 40 percent.
The ignition voltage is more than 11.7 volts.
The engine is not operating in the Power Enrichment, the Decel Fuel Shut-off, or the Catalyst Over-Temperature Modes.
The engine speed is more than 850 RPM.
The engine coolant temperature (ECT) is between -10°C (+14°F) and 110°C (230°F).
The intake air temperature (IAT) is between -10°C (+14°F) and 100°C (212°F) .
The fuel system is operating in fuel trim cells 1, 2, 4, 5, or 6.
Conditions for Setting the DTC
The HO2S voltage does not go below 222 mV for 1.3 seconds.

OR

The short-term fuel trim does not change more than a predetermined value.

Action Taken When the DTC Sets
The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
Conditions for Clearing the MIL/DTC
The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.

 

No wait, I am stupid!

Laerned a lot there.

Great response Jim.... :cool:
