What is the profile ignition pick up?

A profile ignition pick-up (PIP) is a sensor used in internal combustion engines to detect the position of the crankshaft and provide a signal to the engine control unit (ECU) for ignition timing and fuel injection synchronization. It typically generates a voltage signal based on magnetic fields as the crankshaft turns, allowing the ECU to accurately determine when to ignite the air-fuel mixture. This ensures optimal engine performance, efficiency, and emissions control. PIP sensors are commonly found in modern vehicles, contributing to precise engine management systems.
