Spectra S10056 Engine Crankshaft Position Sensor

Spectra S10056 Crankshaft Position Sensor

The Spectra S10056 engine crankshaft position sensor monitors crankshaft speed and position to support ignition timing and engine RPM calculation. It is a direct-fit replacement for select Saturn models, including Saturn L300, LW300, LS2, and LW2 applications.

• Engine crankshaft position sensor for ignition timing and RPM signal input
• Direct replacement for select Saturn L300 and Saturn LW300 applications
• Supports engine speed and crankshaft position monitoring
• Helps eliminate the need for manual distributor timing on equipped systems
• Cross-references Standard Ignition PC537 for the same application

Detailed Product Information

Built for ignition and engine management systems, this Spectra crankshaft position sensor provides the signal the engine control system uses to determine crankshaft position and rotational speed. That information is critical for timing control, fuel delivery coordination, and stable engine operation. The S10056 is listed for 2001-2005 Saturn L300, 2001-2003 Saturn LW300, 2000 Saturn LS2, and 2000 Saturn LW2. If you are replacing a Saturn crankshaft position sensor, this part number is a direct reference to the correct application.

This part cross-references Standard Ignition PC537 for the same application.

Common Problems It Can Help Resolve

• Intermittent no-start or hard-start conditions caused by a weak crank signal
• Rough idle or stalling related to incorrect engine speed input
• Check engine light concerns tied to crankshaft position sensor faults
• Ignition timing errors from an inaccurate crankshaft signal
• RPM gauge or engine speed reading issues on affected vehicles

Installation Notes and Tips

Verify connector style, mounting location, and engine application before installation. On Saturn L300, Saturn LW300, Saturn LS2, and Saturn LW2 vehicles, confirm the original sensor matches the Spectra S10056 part number and the vehicle’s service information. Clear diagnostic trouble codes after installation and perform a system check to confirm the crank signal is being read correctly.

Quality Assurance

Spectra supplies ignition and sensor components for engine management service applications. The S10056 is built as a replacement crankshaft position sensor for the listed Saturn fitments and is intended to restore proper crankshaft speed and position signal input.
