What P0882 means
The TCM power input codes watch the supply voltage of the gearbox module or of its solenoid supply. Without a proper supply all solenoids go dead and the gearbox falls back to its hydraulic emergency gear with maximum line pressure: a fixed gear, harsh engagement, no shifting. Ford's external gearbox modules check a window of 9 to 16 V; GM reports the same under P0562/P0563. P0882 means the supply is too low: Ford sets it below 9 V, continuously and with MIL. Chrysler's RFE, RLE and TE automatics test it when the key goes to run: if the module reads less than 3 V at the transmission control relay outputs while commanding the relay on, the code sets and the solenoids stay dead.
P0882 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0882
- MIL on
- Limp mode in a fixed gear, no shifting
- Torque converter clutch stays open
Common causes of P0882
- Most likelyWeak battery or alternator not charging
- Most likelyTransmission relay, fuse or fuse box module faulty (Chrysler)
- PossibleCorroded ground or supply wire, connector at the module
- Less likelyModule faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0882 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8 | Area: transmission. |
| 82 | The exact fault in that area. |
What to do next
- Note P0882 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0882
What does P0882 mean?
P0882 means "TCM Power Input Signal Low". The TCM power input codes watch the supply voltage of the gearbox module or of its solenoid supply. It is a generic code, so it means the same on every make.
Is it safe to drive with P0882?
Drive gently and only to a workshop. With P0882 the car can go into limp mode (reduced power) to protect itself.
Will P0882 fail an emissions test?
Yes, it can. P0882 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0882 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0882 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
