C2405 on Hyundai by model: symptoms, diagnosis and fix
Multiple owners reported sudden loss of steering assist or abnormally heavy steering effort, sometimes accompanied by warning lights and fault messages. On modern Hyundai platforms this is commonly tied to the Motor Driven Power Steering (MDPS) system, steering angle/torque sensing, or column-related electrical faults. Even when the vehicle remains steerable, the abrupt increase in effort creates a meaningful safety concern at low speeds and during evasive maneuvers.
Common Symptoms
- sudden heavy steering
- loss of power steering assist
- EPS or steering warning light
- steering effort changes while driving
- warning chime or message on cluster
How to Fix
Perform a full scan of EPS/MDPS modules, inspect battery voltage and charging stability, and check steering column connectors and torque/angle sensor data. Depending on findings, repairs may involve software updates, steering column or MDPS component replacement, and steering angle calibration. Intermittent failures should be documented with freeze-frame data because some vehicles behave normally once restarted.

Frequently asked questions
What does C2405 mean on a Hyundai?
C2405 stands for "TPMS Transmitter ID Not Received / Receiver Fault (Manufacturer-Specific)." C2405 is a manufacturer-specific chassis code (common on Toyota/Lexus) within the Tire Pressure Monitoring System family, generally indicating that an expected tire pressure transmitter ID was not received or that a receiver/registration fault occurred. Each wheel sensor transmits a unique ID to the TPMS ECU; a missing or unregistered ID sets this code. The TPMS warning light usually comes on and one or more tire pressures may be unavailable. Manually confirm tire pressures while the fault is active. On Hyundai it is documented across 1 model: Veloster.
What are the most common causes of C2405?
The most common causes of C2405 are: TPMS sensor ID not registered/initialized, Weak or dead TPMS sensor battery, Faulty or missing tire pressure sensor, Receiver, antenna, or wiring fault, RF interference near the vehicle, TPMS control module fault. The specific cause varies by vehicle.
How much does it cost to fix C2405 on a Hyundai?
Published repair estimates on Hyundai range from $250 to $2,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
