P0882 Ram Code - Transmission Control Module Power Input Signal Low
Quick Answer
The transmission control relay is used to supply power to the solenoid pack when the transmission is in normal operating mode. Common causes include Faulty Transmission Control Relay, Transmission Control Relay harness is open or shorted, Transmission Control Relay circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0882 Ram Description
After a controller reset (the ignition key turned to the run position or after cranking the engine), the controller energizes the relay. Prior to this, the PCM verifies that the contacts are open by checking for no voltage at the switched battery terminals. After the relay is energized, the PCM monitors the terminals to verify that the voltage is greater than 3 volts.
What are the Possible Causes of the DTC P0882 Ram?
- Faulty Transmission Control Relay
- Transmission Control Relay harness is open or shorted
- Transmission Control Relay circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)

Frequently Asked Questions about P0882 Ram Code
1. What does the OBDII code P0882 mean on a Ram vehicle?
P0882 indicates that the Transmission Control Module (TCM) is receiving a low voltage signal from its power input, which can affect transmission operation.
2. What are the common symptoms of code P0882 on a Ram?
Symptoms include erratic shifting, transmission stuck in limp mode, poor acceleration, and the check engine light being illuminated.
3. What can cause the P0882 code on a Ram vehicle?
Possible causes include a faulty Transmission Control Module (TCM), damaged wiring or connectors, a blown fuse, low battery voltage, or issues with the power supply to the TCM.
4. Can a weak battery cause code P0882 on a Ram?
Yes, a weak or failing battery can lead to low voltage at the TCM, triggering the P0882 code.
5. How do you diagnose the P0882 code on a Ram vehicle?
Inspect the battery, wiring, connectors, and fuses related to the TCM. Use a multimeter to check voltage levels and continuity in the power supply circuit.
6. Can driving with code P0882 damage the transmission?
Yes, prolonged driving with this code can cause further transmission issues due to improper shifting or operation in limp mode.
7. How can you fix a P0882 code on a Ram truck?
Repair or replace damaged wiring, connectors, or fuses. Ensure the battery and alternator are functioning properly. Replace the TCM if it's faulty.
8. Is the P0882 code related to other transmission codes?
Yes, it can be associated with other transmission-related codes if the power supply issue affects multiple components.
9. Can the P0882 code trigger limp mode in a Ram vehicle?
Yes, the TCM may enter limp mode to protect the transmission when it detects a low power input signal.
10. How much does it typically cost to repair the P0882 code on a Ram?
Repair costs can vary widely, ranging from $50 for minor wiring repairs to over $1,000 if the TCM needs replacement.
