Battery Issue (weak)

[RBJ]

Battery is weak, need new one.   Received a PO882 code is this related to weak Battery, measure 12 volts, it is charging okay,car starts barely. but, I won't go back to Toyota again, because they quoted 1,700 dollars for four new tires,  I got 4 good tires for  $ 800 from tire world. Toyota tried to do us and I am done with them!  The car only cost 16K brand new! I don't work,, I had a stroke. so I'm on  Limited budget!

Code P0882 stands for TCM Power Input Low Is this just a Battery issue?

Hi Robert,A weak Battery could definitely be causing the P0882 code since it often shows up when the TCM isn't getting enough power. Even though you're measuring 12 volts, that’s actually a sign the Battery is pretty low, as a fully charged one should be closer to 12.6 volts at rest.

Swapping in a new Battery might resolve the issue without needing to spend on costly repairs. It's understandable not wanting to go back to the dealership after they quoted such a high price for tyres especially when you found a much better deal for half the cost elsewhere. Unfortunately dealer prices these days.👍

I charged for 5 hours and went up to 13.5 volt while charging.  I removed the charger and it dropped to 12.5 with out starting.  It is time change it, but we can't until Friday. That would suck if we ruined something.  We can only try.  Thanks for responding.

I wasn't in the car when my wife had the wrench light come one, but it was at a stop light and maybe she had AC running and the Battery dipped low enough to set the code

FYI  The Battery was replaced and all is goodl. Thanks for advising.  I cleared the codes and ran two drive cycles.   Everything is good!
