Most Reported On
C1A70 is an OBD-II diagnostic trouble code meaning “Power Steering Control System Malfunction (EPS).” C1A70 is a manufacturer-specific chassis code (common on Toyota/Lexus) indicating a malfunction within the Power Steering Control System. It is typically stored when a controlling module receives an internal-fault signal from the Power Steering ECU, meaning the electric power steering assist is degraded or has failed. The steering wheel may feel stiff or heavy and require much more effort to turn. Because loss of power assist directly affects controllability, this should be addressed promptly. This code is most commonly reported on 2021-2025 Nissan Rogue, with repair costs ranging from $250 to $1,800.
