OBD-II Code
P0880
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.
Indicative cost (USD)
$300–$2,600
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0880 is a TCM ignition or power input signal fault, set when the TCM detects that its switched-power feed is present but does not match the expected state given key-on and engine-run inputs.
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.

Start with the absolute cheapest check
load-test the battery and verify alternator output between 13.8V and 14.6V at idle, because a weak battery is the single most common cause of TCM power codes on modern vehicles. Next, locate the TCM ignition-feed fuse (often a 15-20A in the underhood PDC or TIPM) and back-probe the TCM connector with key on; the feed should read battery voltage minus 0.2V or less, and should not droop below 11.0V during cranking. Caveat: on platforms with a smart power module (Chrysler TIPM, GM BCM-controlled TCM feed), the actual cause is often the upstream module not commanding the relay closed.

- 2007-2014Chrysler 300, Charger, Town & Country, and Grand Cherokee with the original TIPM-7 has a known internal relay failure on the TCM feed and is the highest-volume P0880 platform in North America; replacement TIPM or socketed-relay mod is the standard fix.
- 2008-2013GM 6L80-equipped Silverado, Tahoe, and Camaro see P0880 from internal mechatronic (TEHCM) power-input circuit failure that requires mechatronic replacement.
- 2011-2016Ford F-150 with the 6R80 throws P0880 from BCM-switched TCM power loss.
- 2009-2015VW and Audi with the 09G or DQ250 DSG see P0880 from a cracked mechatronic connector sleeve letting ATF wick into the power pin.
Estimated repair$300 to $2600.
