• Supports synchronization of fuel injector and coil firing sequence
• Direct-fit replacement for select BMW ignition sensor applications
• Fits 2001-2006 BMW M3, without wires
• Fits 2000-2003 BMW M5, exhaust
• Fits 2003 BMW Z8, intake
• Fits 2001-2002 BMW Z3, without wires
• Fits 2000-2002 BMW Z8

Detailed Description

Built for engine management systems that rely on accurate camshaft signal input, the Spectra S10553 helps the ECU determine which cylinder is firing and maintain proper ignition timing. This part number is listed for BMW M3, BMW M5, BMW Z3, and BMW Z8 applications, making it a focused replacement for vehicles that require precise camshaft position feedback. This part cross-references Standard Ignition PC771 for the same application.

What It Helps Solve

• Check engine light related to camshaft position signal faults
• Hard starting caused by incorrect camshaft timing input
• Rough idle from inconsistent cylinder synchronization
• Misfire conditions tied to timing or injector sequencing errors
• Stalling or hesitation linked to sensor signal loss

Installation Notes and Tips

Verify the connector style and sensor location before installation, especially on BMW M3 and BMW Z8 applications where fitment varies by position. Confirm whether the vehicle uses the intake, exhaust, or no-wire configuration listed for your application. Use the vehicle’s service information to clear fault codes and confirm proper signal operation after replacement.

Quality Assurance

Spectra manufactures ignition and engine management sensors for OE-style replacement needs, with product information focused on accurate fitment and function for the listed BMW applications.
