IMA light on - p1447, 127k miles '01 ?

[masscommuter]

covered by warranty?

any idea what I'm facing? I see so many posts on P1447 . .

1 pm today:
Autozone OBC readout[s]: P1447 MIL OFF MONITORS 0 INC 8 READY MISFIRE FUEL COMP CATLYST EVAP 02 SNSR 02 HTR EGR

Perhaps 6 wks ago, I got another P code ( I lost it ) which translated to O2 sensor (#1 sensor?) . . . autozone showed 2 options, from Bosch $150 or Denso $360.

Today: IMA light went out after startup, then came back on and stayed on, also at next shutdown / startup.

IMA charge dropped from ~40% to 2 bars,
then I noticed Charging Bars were happening (back to normal? but IMA light still on),
& it got back up to 4 bars when I reached home.

thanks in advance for any pointers . .

Sorry, not covered by warranty.

Insight Oxygen sensors tend to be the more expensive ones.

It's possible you're under warranty, but pretty unlikely - unless your '01 was sold in '03.

My understanding is that the P1447 code is the "unbalanced" pack code, though I don't have it in any of my code charts. Most people would recommend a grid charge. You'd likely be able to get by if you just let the car keep charging after it drops down to 2 bars like it did... Contrary to what most people at IC believe, I think the car likely does have something at least analogous to a balancing routine, a rough balance, after a negative recal (when the gauge drops to those 2 bars). I've seen data for charging behavior that I can't interpret in any other way...

P1447-77 and P1449-78 are both the same errors technically - "Battery Module Deterioration".

I think they're fundamentally the same thing, the only thing that leads you to believe one is a lesser error than the other is the fact that you still get limited assist/regen with P1447 and not P1449.

It does.
