If your vehicle experiences hard starting, sluggish acceleration, intermittent stalling, or the check engine light is on, it is likely the crankshaft position sensor is aging or damaged, causing the ECU to fail to obtain accurate crank speed and position signals. When working properly, this sensor monitors crank angle and engine RPM to provide data for ignition timing and fuel injection control, ensuring smooth engine operation. OEM number 0261210263; fits Buick Regal 2.0, Buick Epica 2.0, Chevrolet Captiva 2.4L (large head version). Installation requires ensuring clearance between the sensor and crank signal wheel meets standard and tighten bolts to specified torque to avoid signal interference or loose connections.
