Detailed Product Information

The Spectra S10554 is an engine crankshaft position sensor used in ignition and engine management systems. It reads crankshaft position and rotational speed so the engine control system can maintain proper timing and monitor engine operation. This part is a practical replacement when the original sensor is no longer sending a stable signal. Compatible With 1996-2000 Ford Explorer and 1997-2001 Mercury Mountaineer, this sensor supports the applications commonly searched as Ford Explorer crankshaft position sensor and Mercury Mountaineer crankshaft position sensor. This part cross-references 1L2Z6C351AA and 5S1760 for the same application.

Common Issues This Part Can Address

• Hard starting caused by an inconsistent crankshaft signal
• Stalling or intermittent engine shutdown related to sensor failure
• Rough running from incorrect ignition timing input
• Check engine light conditions tied to crankshaft position sensor faults
• Unstable RPM readings during engine operation

Installation Notes and Tips

Verify the connector style and mounting location against the original sensor before installation. Inspect the harness, terminals, and nearby wiring for damage or corrosion, since signal issues can come from the sensor circuit as well as the sensor itself. After installation, clear any stored diagnostic trouble codes and confirm stable engine speed and timing data. For fitment searches, this S10554 crankshaft position sensor matches 1996-2000 Ford Explorer and 1997-2001 Mercury Mountaineer applications.
