Electric power steering unit for CITROËN C1, PEUGEOT 107 and TOYOTA Aygo
This steering ECU (EPS) is designed for Citroën C1, Peugeot 107 and Toyota Aygo models and is identified by part numbers frequently searched by professionals: 89650-0H011, B0 00652180 and related codes. Suitable for mechanics and experienced DIY enthusiasts, this unit restores or replaces the electronic control of the electric power steering system, helping to remove steering assist faults, steering torque irregularities and warning lamp errors. Because many buyers look up parts by product code, the main references are listed below for quick identification.
Application And Function
The unit controls the electric power steering motor and processes input from the torque sensor and vehicle speed signals to deliver variable steering assist. Proper operation ensures stable steering feedback, reduced effort at low speeds and precise centering at higher speeds. When faulty, it can cause increased steering effort, intermittent assistance, or steering warning lights on the instrument cluster.

Installation Recommendations
Always follow safe workshop procedures. Before starting, disconnect the battery to avoid short circuits and potential damage to the unit. Center the steering wheel and lock the wheels in the straight-ahead position. Handle the connector pins carefully and inspect plugs and wiring for corrosion or damage before installation. After fitting, verify all mechanical fastenings and electrical connections. Many EPS units require initialization or adaptation with a suitable diagnostic tool (for example DiagBox or an equivalent tool compatible with Stellantis systems) to calibrate the torque sensor and clear fault codes. If you are not equipped with the correct diagnostic equipment or are unsure about the coding/initialization process, professional installation is recommended.
Most Common Reason For Failure
Failures are most often caused by electrical issues and environmental damage: water ingress, corroded connectors, damaged wiring looms, or internal electronic component degradation due to heat and vibration. Mechanical impacts (accidents or heavy steering column forces) and long-term wear on sensors or motor components also contribute. Faults frequently appear on higher-mileage vehicles or cars with prior water exposure.
Practical Notes
Customers and workshops commonly search using the part number 89650-0H011 or other codes listed above. Before installation, inspect the unit visually for connector condition and match the electrical plug layout. Replacing the EPS unit often solves steering assist faults, but remember that correct initialization and system checks after installation are essential for safe steering behavior.
