Direct-Fit Crankshaft Sensor

The Standard Ignition PC525 crankshaft sensor is built as a direct-fit replacement for specific engine applications. It provides the position signal the engine control module needs for accurate ignition timing and fuel delivery. Mechanics and DIY technicians working on compatible vehicles will find it matches the original mounting points and connector style.

Signal Reliability Limits

The sensor operates within the electrical tolerances defined by the vehicle manufacturer for crankshaft position feedback. Signal accuracy depends on correct air-gap alignment during installation and a fault-free wiring harness. Contamination, damaged trigger wheels or excessive vibration can degrade the output even when the sensor itself is functional.

Transparent Housing Durability

The transparent housing lets you visually inspect the internal electronics for moisture ingress or physical damage before fitting. The moulded connector pins resist corrosion and key to the factory harness to prevent misconnection. Its one-piece construction eliminates separate seals that can leak, simplifying the swap and reducing comeback risk.
