Crankshaft Crank Position Sensor For GM GMC Chevrolet Cadillac Pontiac 12560228

Crankshaft Crank Position Sensor for GM GMC Chevrolet Cadillac Pontiac 12560228

This crankshaft crank position sensor, referenced under OEM number 12560228, reads crankshaft rotation and sends timing signals to the engine control module so ignition and fuel delivery stay synchronized.

Overview

This crankshaft crank position sensor is a direct-fit replacement for a failed or intermittent factory sensor on a range of GM engines. The crank position sensor delivers accurate crankshaft speed and position data to the ECU, helping restore stable idle, clean starts, and proper ignition timing. It is intended for DIY mechanics and professional technicians servicing GM, GMC, Chevrolet, Cadillac, and Pontiac vehicles.

• Magnetic pickup design generates a clean signal across the RPM range
• Plug-and-play connector matches the factory harness
• Housing dimensions matched to the OEM 12560228 mounting footprint
• Built to hold signal accuracy through repeated heat cycles

Fits These Machines

• for GM vehicles equipped with the 12560228 sensor application
• for GMC models using this crank position sensor
• for Chevrolet models using this crank position sensor
• for Cadillac models using this crank position sensor
• for Pontiac models using this crank position sensor

On-The-Job Use

• Replacing a sensor that causes hard starting or stalling
• Diagnosing no-start or misfire conditions traced to crank signal loss
• Routine ignition system service on high-mileage GM engines
• Restoring tachometer and timing readings after sensor failure

Specs At A Glance

Good To Know

Q: Does this sensor need programming after installation? A: A crank position sensor of this type is a plug-and-play part and does not require programming. A scan tool relearn may be needed on some vehicles per factory procedure.

Q: What are common signs of a failing crank position sensor? A: Hard starts, random stalling, misfires, and a no-start condition are typical symptoms. A stored crank sensor code usually confirms the diagnosis.

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