Engine Crankshaft Position Sensor for Chevy Silverado Express GMC Sierra 98-09

Engine Crankshaft Position Sensor for Chevy Silverado Express GMC Sierra

This engine crankshaft position sensor monitors crankshaft rotation and sends timing signals to the engine control module so ignition and fuel delivery stay synchronized on 1998 through 2009 Chevy Silverado, Express, GMC Sierra and related models.

Overview

This crankshaft position sensor is a direct-fit replacement for worn or failed factory units on Chevrolet and GMC trucks and vans. The sensor reads the reluctor wheel and reports engine speed and crank position to the ECU, which keeps spark timing and injector pulses accurate. It is intended for DIY mechanics and professional technicians servicing 1998 to 2009 full-size GM trucks, SUVs and vans.

Good To Know

Q: How do I know if my crankshaft position sensor has failed? A: Common signs include a no-start condition, random stalling, rough running and a check engine light with a crank sensor code. A scan tool can confirm the fault before you replace the part.

Q: Is this sensor difficult to install? A: On most Chevy and GMC applications the sensor mounts on the engine block or timing cover and swaps with basic hand tools. Disconnecting the battery first and matching the connector orientation helps speed the job.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
