P0880 Dodge Code - TCM Power Input Signal
Quick Answer
The P0880 OBD-II trouble code for Dodge vehicles refers to a fault in the Transmission Control Module (TCM) power input signal. Common causes include Faulty TCM power input circuit: A damaged or faulty power input circuit can prevent the TCM from receiving the necessary power supply, Loose or corroded electrical connections: Poor connections between the TCM and the power source can disrupt the power input signal, Blown fuse: A blown fuse in the TCM power supply circuit can cause a loss of power to the module. 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 P0880 Dodge Description
The P0880 OBD-II trouble code for Dodge vehicles refers to a fault in the Transmission Control Module (TCM) power input signal. The TCM is a crucial component of the vehicle's transmission system, responsible for controlling shifting patterns, torque converter lockup, and other transmission functions. The power input signal is essential for the TCM to operate correctly, as it provides the necessary power supply for the module to function effectively.
Common Causes of P0880 Dodge
- Faulty TCM power input circuit: A damaged or faulty power input circuit can prevent the TCM from receiving the necessary power supply.
- Loose or corroded electrical connections: Poor connections between the TCM and the power source can disrupt the power input signal.
- Blown fuse: A blown fuse in the TCM power supply circuit can cause a loss of power to the module.
- Faulty TCM: In some cases, the TCM itself may be faulty and unable to receive the power input signal correctly.
Symptoms of P0880 Dodge
- Erratic shifting patterns: The vehicle may experience difficulty shifting gears smoothly, with abrupt or delayed shifts.
- Transmission slippage: The transmission may slip out of gear or struggle to maintain the correct gear ratio.
- Loss of power: The vehicle may lose power unexpectedly, especially during acceleration.
- Check Engine Light: The Check Engine Light may illuminate on the dashboard, indicating a fault in the transmission system.
How to Fix P0880 Dodge
- Check electrical connections: Begin by inspecting the electrical connections to the TCM, ensuring they are secure and free from corrosion.
- Test power input circuit: Use a multimeter to test the power input circuit for continuity and voltage, identifying any potential issues.
- Replace blown fuse: If a blown fuse is identified, replace it with a new one of the same amperage rating.
- Replace TCM: If all other potential causes have been ruled out, consider replacing the TCM with a new unit to resolve the power input signal issue.
Cost to Fix P0880 Dodge
The cost of repairing a P0880 TCM power input signal code can vary depending on the underlying cause of the issue. In general, replacing a blown fuse or addressing loose electrical connections may only require minimal parts and labor costs, ranging from $50 to $200. However, if the TCM itself needs to be replaced, the cost can increase significantly, with TCM units typically ranging from $300 to $800, not including labor costs.
