OBD-II Code
P0882
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.

From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0882 is the low-voltage variant of the TCM power input fault, set when the TCM ignition feed drops below a defined threshold (commonly 9.0V on most domestic platforms, 8.5V on some European applications) for longer than a calibrated dwell, typically 100-500 milliseconds.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

Cheapest first
- load-test the battery and confirm CCA is within 80 percent of rated.
- Next, with the engine cranking, measure voltage directly at the TCM connector power pin (not at the battery), because the relevant droop is at the TCM, not the battery post; spec is to stay above 9.5V at the TCM during cranking.
- Caveat: P0882 will often set as a secondary fault after a no-start crank attempt with a weak battery, then clear and not return once the battery is recharged or replaced.

- 2007-2013Chrysler with TIPM-7 (300, Charger, Grand Cherokee, Town & Country) sees P0882 from TIPM internal TCM relay contact pitting; the underhood relay relocation kit (external socketed relay) is the durable workaround.
- 2008-2014GM 6L80-equipped Silverado and Tahoe throw P0882 from corroded underhood ground G103, common in rust-belt vehicles.
- 2011-2017Ford F-150 with the 6R80 logs P0882 when the megafuse or BJB feed for the TCM degrades.
- 2010-2016Mercedes with 7G-Tronic and dual-battery systems sees P0882 from auxiliary battery failure that goes unnoticed until the TCM logs the code.
