Crankshaft sensor for engine diagnostics

The Standard Ignition PC191 crankshaft sensor provides the signal the engine control unit uses to time ignition and fuel delivery. It is intended for technicians and vehicle owners replacing a failed or erratic sensor on compatible applications.

Transparent housing and direct manufacturer supply

The sensor ships directly from the manufacturer with a transparent housing that allows visual inspection of the internal assembly. Orders of $75 or more qualify for free shipping from the supplier.

Behaviour under sustained engine operation

Under continuous engine running the sensor maintains its output signal without drift caused by heat soak. It is designed to withstand the vibration and temperature cycles present during extended driving rather than only during brief test conditions.

Questions about this item

How is the PC191 crankshaft sensor installed and what step is often missed?

The PC191 mounts directly to the engine block at the crankshaft position; the step often missed is fully seating the sensor and torquing the mounting bolt to specification before reconnecting the electrical connector.

What maintenance or replacement will the PC191 crankshaft sensor need later?

The PC191 is a sealed electronic sensor with no serviceable parts; it requires no periodic maintenance and is replaced only if it fails or shows signal errors.

What limit appears first on the PC191 crankshaft sensor under sustained engine heat and vibration?

The primary limit is thermal cycling and vibration fatigue on the internal Hall-effect circuit and pigtail wiring, which can degrade the signal output over time.
