On a 2003 Infiniti I35, C1121 points to the front-left ABS solenoid circuit inside the ABS actuator assembly. Since you only provided the vehicle information, the first step is to confirm whether the ABS, SLIP, or traction-control lights are on and whether the code returns immediately after being cleared.
Check the ABS actuator connector and wiring for corrosion, loose terminals, or damage before replacing the actuator. If the wiring and power supplies are good, the fault is often internal to the ABS actuator/electric unit, which may need repair or replacement. This code is not usually caused by the left-front wheel speed sensor.
