Engine & Performance Warehouse 10938879 GM OEM Crankshaft Position Sensor

The Engine & Performance Warehouse 10938879 is a direct-fit crankshaft position sensor designed as an OEM-specification replacement for a wide range of General Motors vehicles. The crankshaft position sensor is a critical engine management component that monitors the rotational speed and position of the crankshaft, delivering precise data to the engine control module (ECM) to optimize ignition timing and fuel injection. A failing or failed crank sensor commonly triggers symptoms such as hard starting, stalling, rough idle, misfires, and an illuminated check engine light.

Key Features:

• OEM-specification design for direct, no-modification fitment
• Precise crankshaft speed and position monitoring for accurate ECM data
• Supports correct ignition timing and fuel injection sequencing
• Manufactured to meet original equipment tolerances and performance standards
• Plug-and-play replacement — uses factory wiring connector
• Helps resolve hard start, stall, misfire, and check engine light conditions related to crankshaft position
