Hello impala enthusiasts. I'm having a issue with this P0410 code that pops up. Someone told me that it could be the 02 sensors. Is this a accurate assessment??

How old are your O2 sensors? I generally change them out 50k-60k miles and only use genuine AC-Delco AFS75 sensors.

From the Web:
How do I fix code P0410?


What repairs can fix the P0410 code?

1. Replacing the air injection pump and power relay.
2. Replacing O2 sensors that respond too slow as they age.
3. Replacing the air injection pump intake filter clogged with debris.

I looked P0410 in the F(Camaro) factory service manual. The diagnostics center on the air injection pump.

Could be a blown fuse due to other circuits, bad relay, or air pump failure. Could be a blockage.

What I would not do is replace the 02 sensors "just because" New parts are not necessarily functioning parts these days.

The PCM runs the air injection pump during closed loop and looks for a change in the rich/lean ratio. If there is not a change it sets P0410. It does one set of tests at idle, then does another set of tests above idle.

If the O2 sensors are switching, and you have no O2 codes I suggest you get a mechanic to use live data or oscilloscope information to check the O2 switching rate before changing any O2 sensors. Even when the PCM sets codes for O2 problems it can be wiring issues and not the actual O2 sensor at fault.

If you are going to diagnose this yourself get a factory service manual.

I, friends, and family have several cars with over 120,000 miles and factory O2 sensors. No codes good fuel mileage. O2 sensors can fail due to contamination and switch slow but it can be checked by a good mechanic.
