[DeclanLynn]

Solution for fault code p0121: In this case, you need to drive the car to a repair shop or 4S shop for throttle cleaning and throttle pedal position sensor inspection. After the repair, use professional equipment to clear the fault code. Fault code p0121 indicates that the car's throttle or throttle pedal position sensor is malfunctioning. When the car's throttle has severe carbon deposits, the car will experience problems such as weak acceleration and idle speed shaking, and fault code p0121 will appear during OBD inspection. In this case, the car's throttle needs to be cleaned immediately to allow the engine to work better and reduce the car's fuel consumption.
