A-NAFTULY Crankshaft Position Sensor for 1999–2006 GM Trucks & SUVs — Plug-and-Play Single Unit, OEM Fit

A-NAFTULY's crankshaft position sensor is a direct-fit replacement designed to restore accurate engine timing signals on compatible 1999–2006 GM V6/V8 vehicles without programming or splicing.

If your Silverado, Sierra, Tahoe, Yukon, Avalanche, Suburban, Camaro, Trailblazer, Envoy, Savana, or Cadillac Escalade is showing symptoms like rough idle, poor acceleration, or intermittent stalling, a worn crankshaft position sensor can be a common cause. This A-NAFTULY sensor is built as a plug-and-play substitute for OEM references 12560228, 12555566, 5S1692 and several equivalent part numbers. It is supplied as a single replacement sensor with a straightforward mounting design and a sealed electrical connector to match factory specifications.

How will this sensor fit my specific GM vehicle and engine?

The sensor supports a wide range of GM models and engine sizes primarily from 1997–2007 model years. Fitment covers Silverado and Sierra 1500/2500, Tahoe, Yukon, Avalanche, Suburban, Express, Trailblazer, Envoy, Savana, Camaro, Corvette, and Cadillac Escalade among others. Always compare the mounting style and connector of your original sensor to confirm compatibility before purchase.
