The crankshaft position sensor in the Suzuki Cultus monitors the position and speed of the crankshaft, providing critical information to the ECU to control ignition timing and fuel injection. A faulty crankshaft position sensor can lead to engine misfires, stalling, o r difficulty starting the engine.

Symptoms of a Faulty Crankshaft Position Sensor:

Engine Stalling o r Misfiring: A faulty sensor can cause the engine to misfire o r stall because the ECU is unable to determine the proper timing for ignition o r fuel injection.

Difficulty Starting the Engine: The engine may crank but fail to start because the ECU cannot detect the position of the crankshaft.

Check Engine Light CEL: A malfunctioning crankshaft sensor can trigger the CEL, alerting the driver to an issue with the sensor.

Poor Acceleration: A faulty sensor may result in hesitation o r a decrease in engine performance, especially during acceleration.

How to Fix:

Inspect the Sensor and Wiring: Check for any visible damage to the sensor o r its wiring. Corrosion o r loose connections can prevent the sensor from working correctly.

Replace the Crankshaft Position Sensor: If the sensor is faulty o r worn out, it needs to be replaced. This typically requires accessing the sensor near the crankshaft pulley.
