1. What is P0882 in Ford F-150?

The P0882 OBD-II code stands for Transmission Control Module (TCM) Power Input Low. For the Ford F-150 (2017-2023)—America’s best-selling pickup—this code targets the TCM power circuit in the 10R80 10-speed automatic transmission (standard in 3.5L EcoBoost, 5.0L Coyote V8, and 3.0L Power Stroke-equipped XLT, Lariat, and Raptor trims).

The TCM relies on a steady 12V power supply (from the vehicle’s battery, via a dedicated fuse and harness) to control transmission shifting, torque converter lockup, and temperature monitoring. P0882 triggers when the TCM detects power below 9.5V—signaling a blown fuse, corroded wiring, or faulty TCM. This is a top issue for 2019-2022 F-150s with the 10R80, addressed in Ford Technical Service Bulletin (TSB) 21-2244: the TCM’s power harness (located under the driver’s seat) is prone to corrosion from road salt and moisture.

F-150 Specific Note: The 10R80’s TCM is mounted under the driver’s seat (2017-2020 models) or behind the glove box (2021-2023 models). XLT and Lariat trims—used heavily for towing (max 14,000 lbs for 3.5L EcoBoost 4x4s)—are 2.7x more likely to trigger P0882: towing vibrations loosen harness connections, while road salt accelerates terminal corrosion.

2. Common Causes of P0882 in 2017-2023 F-150

P0882 in F-150 10R80 models stems from TCM power circuit issues—below are real-world cases diagnosed with the ICARZONE UR1000:

• Blown TCM Fuse (2020 F-150 Lariat 3.5L EcoBoost): An Lariat owner with 78,000 miles reported "Transmission Fault" warnings. The UR1000’s TCM Power Test showed 0V (normal: 11.5–12.5V). The 15A TCM fuse (located in the under-hood fuse box, Slot F27) was blown—replacing it with OEM #DL3Z-14526-A fixed P0882.
• Corroded TCM Harness (2019 F-150 XLT 5.0L): An XLT owner’s P0882 appeared after winter. The UR1000’s Circuit Continuity Test found 15Ω resistance (normal: <0.5Ω) in the under-seat harness. Road salt corroded the TCM connectors—cleaning with electrical contact cleaner (#CRC 05110) and applying dielectric grease resolved the issue.
• Faulty TCM (2018 F-150 Raptor 3.5L EcoBoost): A Raptor owner’s P0882 persisted after fuse/harness repairs. The UR1000’s TCM Internal Test confirmed the module couldn’t regulate power input. Replacing the TCM (OEM #HC3Z-7G391-A) and programming it with the UR1000’s "Ford TCM Calibration" tool fixed the code.
• Loose Battery Connection (2021 F-150 King Ranch 3.0L Power Stroke): A King Ranch owner’s P0882 was intermittent. The UR1000’s Battery Voltage Test showed fluctuating power (8–11V). Tightening the negative battery terminal (loosened by towing vibrations) restored steady 12V to the TCM.

3. Key Symptoms of P0882 in F-150 10R80

P0882 symptoms in the F-150 are transmission and electrical-focused—watch for these critical signs that affect drivability:

Ford service data highlights these 2017-2023 F-150 configurations with the highest P0882 occurrence rates (all paired with the 10R80 10-speed auto):

5. Diagnose P0882 with ICARZONE UR1000

Diagnose P0882 in your F-150 10R80 accurately with the UR1000’s Ford-specific TCM tools. Follow these steps (engine off, key in "ON" position):

Case Example: A 2019 F-150 XLT failed Step 2 (8.2V) and Step 4 (12Ω). The UR1000’s Component Location Tool guided harness access (remove driver’s seat trim). Cleaning the connectors and replacing the blown fuse fixed P0882—verified by test drive (smooth shifting, no limp mode).

6. How to Fix P0882 in F-150 10R80

Resolve P0882 in your F-150 with these UR1000-verified solutions—tailored to the 10R80 transmission:

1. Replace Blown TCM Fuse (Simplest Fix)

1. Confirm blown fuse via UR1000’s Step 3. Locate the under-hood fuse box (driver’s side, near the battery) and open the cover.
2. Find Slot F27 (labeled "TCM Power")—use the fuse puller inside the box to remove the 15A fuse.
3. Inspect the fuse for a broken filament (sign of a short). Replace it with an OEM 15A mini fuse:
   • 2017-2020 F-150: #DL3Z-14526-A
   • 2021-2023 F-150: #BL3Z-14526-A (heat-resistant design)
4. Reinstall the fuse box cover. Clear P0882 with UR1000 and test drive—check for limp mode or shifting issues.
5. If the fuse blows again within a week, use UR1000 to check for a short in the TCM harness (Step 4).

2. Repair Corroded TCM Harness (TSB 21-2244 Fix)

1. Confirm corrosion via UR1000’s Step 4. Access the TCM harness:
   • 2017-2020 F-150: Remove driver’s seat trim (4 Torx screws) to access the under-seat TCM.
   • 2021-2023 F-150: Remove glove box (press side tabs) to reach the behind-glove-box TCM.
2. Disconnect the TCM’s power connector (press the tab). Spray electrical contact cleaner (#CRC 05110) into both connector halves.
3. Use a small brush to scrub green/white corrosion from the pins—avoid using metal tools (prevents pin damage).
4. Dry the connector with compressed air (low pressure). Apply dielectric grease (#Permatex 81150) to the pins to prevent future corrosion.
5. Reconnect the harness, reassemble the trim, and clear P0882 with UR1000. Retest TCM power (Step 2) to confirm 11.5–12.5V.

3. Replace Faulty TCM

1. Confirm TCM failure via UR1000’s internal test. Disconnect the negative battery terminal for safety.
2. Access the TCM (follow Step 1 above) and disconnect all connectors (label them to avoid mix-ups).
3. Remove the TCM mounting bolts (2–4 Torx screws) and pull the old module free.
4. Install an OEM TCM:
   • 2017-2020 F-150: #HC3Z-7G391-A
   • 2021-2023 F-150: #BL3Z-7G391-A
5. Reinstall the TCM and connectors. Use the UR1000’s "Ford TCM Programming" tool to calibrate the new module (matches VIN and transmission specs).
6. Reconnect the battery, clear P0882, and test drive—verify smooth shifting and no power warnings.

7. P0882 Repair Costs & Maintenance Tips

P0882 repair costs for the F-150 10R80 vary by cause. Use this table to budget:

Maintenance Tips for F-150 10R80 Owners

• XLT/Lariat (cold climates): Inspect the TCM harness every 6 months—clean connectors with contact cleaner and reapply dielectric grease (follows TSB 21-2244 guidelines).
• Check the 15A TCM fuse (Slot F27) during oil changes—carry a spare fuse in the glove box for emergency replacements.
• Tighten battery terminals quarterly—towing vibrations loosen connections, causing intermittent TCM power drops.
• Avoid power washes under the driver’s seat (2017-2020 models) or behind the glove box (2021-2023 models)—moisture causes TCM connector corrosion.
• Perform the UR1000’s TCM Health Check every 15,000 miles — monitor power input and harness continuity to catch issues before P0882 triggers.
