Camshaft Position Sensor 12561211 For Chevrolet Silverado Tahoe GMC Yukon Sierra

Camshaft Position Sensor 12561211 for Chevrolet Silverado Tahoe GMC Yukon Sierra

This camshaft position sensor, referencing part number 12561211, reports camshaft rotation to the engine control module so fuel injection and ignition timing stay accurate on Chevrolet Silverado, Tahoe, GMC Yukon and Sierra models.

Overview

This camshaft position sensor is a replacement part for the factory unit and cross-references 12561211. It signals the ECU when each cylinder reaches its intake stroke, which keeps sequential fuel injection and variable valve timing events properly phased. It suits owners and shops repairing Chevrolet and GMC trucks and SUVs that show cam sensor codes or rough running symptoms.

Good To Know

Q: What symptoms point to a bad camshaft position sensor? A: Rough idle, hard starting, poor fuel economy and a check engine light with a cam sensor code are typical signs. A diagnostic scan helps confirm the sensor is the cause before replacement.

Q: Does this sensor need calibration after installation? A: Most Chevrolet and GMC applications accept the sensor without programming because the ECU reads it directly. Clearing stored codes after the install lets the module relearn the signal.

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