Specifications

The PAI 650667 Crankshaft Position Sensor (Timing Reference Sensor, TRS) is a direct OEM replacement for Detroit Diesel 23527339, designed for the Series 60 engine family (11.1 L, 12.7 L, 14 L). With a 2-pin rectangular connector and 3.60″ overall length (OAL), this sensor includes an O-ring to ensure a proper seal and reliable performance.



Manufactured under ISO-9001 standards in the USA, this sensor is built for durability in harsh conditions—temperature extremes, vibration, and exposure typical of heavy-duty diesel applications. Backed by PAI’s 2-year unlimited-mileage warranty, it ensures dependable crankshaft position data for ignition/fuel timing, reduced misfires, improved performance, and more consistent starts. Available from Wofford Truck Parts for fleet service, engine rebuilds, or timely replacements.
