Prenco 4D-1098 Engine Crankshaft Position Sensor

The Prenco 4D-1098 is an engine crankshaft position sensor designed to monitor the precise position and rotational speed of the crankshaft. This critical sensor provides real-time data to the engine control unit (ECU) to ensure optimal engine performance and efficient operation.

Key Features:

• Monitors crankshaft position and rotation speed (RPM) for accurate engine timing
• Provides essential data for proper ignition timing and fuel injection control
• Enables the ECU to optimize spark timing and fuel delivery for maximum efficiency
• Helps detect and monitor cylinder misfires for improved diagnostics
• Direct replacement sensor for reliable engine operation

The crankshaft position sensor is one of the most important sensors in modern engine management systems. It works by detecting the rotation of the crankshaft and generating voltage signals that the ECU uses to calculate precise ignition and fuel injection timing. Without a functioning crankshaft position sensor, the engine will not start or run properly. This sensor is essential for maintaining smooth engine operation, optimal fuel economy, reduced emissions, and maximum power output.
