2009- Hyundai I20 Crank sensor (G4FA) is a critical engine sensor designed for Hyundai I20 models starting from 2009. This sensor monitors the position and rotational speed of the crankshaft, providing vital information to the engine control unit for precise timing of fuel injection and ignition. Accurate crankshaft data is essential for efficient engine operation and starting performance.
This crank sensor fits the G4FA engine variant of the Hyundai I20, making it important to compare the part with the previously installed sensor to ensure compatibility. Buyers should check the sensor’s physical connectors and mounting points against the existing unit to confirm a match before purchasing.
Located near the crankshaft, this sensor detects the crankshaft’s movement and sends pulses to the vehicle’s electronic control system. A faulty crank sensor can cause issues such as engine misfires, starting problems, or stalling. Replacement with the correct sensor part number and type is important for restoring proper engine function.
