A-Premium Crankshaft Position Sensor for Chevrolet & GM — 3-Pin Black Housing, Direct-Fit OE Replacement

The A-Premium Engine Crankshaft Position Sensor is a direct-fit replacement sensor designed to restore accurate crank timing for compatible Chevrolet, GMC, Buick, Cadillac and related vehicles.

This aftermarket crankshaft position sensor from A-Premium is built to the same fitment points and electrical interface as many original equipment units, offering a three-pin blade connector and black molded housing. It’s supplied one per box and cross-references several OEM numbers so you can match it to your vehicle’s factory part. The sensor helps the engine control module receive position and rotational speed information from the crankshaft so ignition timing and fuel injection can be regulated by the vehicle computer.

How will this sensor fit my vehicle model and year?

The A-Premium sensor lists broad compatibility across GM platforms and related brands. Before purchase, compare the sensor’s reference numbers and three-pin connector style with your current unit or repair manual to confirm a match.

Installation is typically straightforward for mechanically inclined owners: locate the factory sensor on the timing cover or bellhousing area, unplug the harness, remove the mounting bolt(s), and swap in the new sensor. Always follow safety precautions and torque specifications from your repair manual.

• Disconnect the battery before beginning to avoid electrical shorts.
• Inspect the wiring harness and connector for corrosion or damage; replace harness components if necessary.
• Use OEM torque specs for mounting bolts and confirm secure connector engagement to prevent intermittent faults.
• After installation, clear any stored diagnostic codes and verify engine operation under idle and driving conditions.

It’s appropriate for owners seeking an aftermarket direct-fit part with clear OEM cross-reference numbers and standard three-pin blade connectivity. If you need a sensor that matches existing mounting and electrical interfaces and want a cost-effective replacement option, this unit is a practical choice. For vehicles not listed or when in doubt, verify fitment with your VIN and the sensor reference numbers before purchasing to ensure a trouble-free replacement.
