Standard Motor Products Engine Crankshaft Position Sensor

Why Standard Motor Products Crankshaft Position Sensors Stand Apart

The engine crankshaft position sensor is one of the most critical inputs your powertrain control module (PCM) receives. Engine crankshaft position sensors monitor the rotational speed and precise position of the crankshaft in real time, feeding data the PCM uses to set ignition timing, calculate RPM, and synchronize fuel delivery. As Standard Motor Products (SMP) puts it, even the slightest delay or inaccuracy can affect timing — directly impacting engine performance, fuel economy, and emissions.

The Standard® and Blue Streak® Sensor Programs

SMP offers crankshaft position sensors under two distinct product lines. The Standard® line focuses on premium OE-replacement accuracy, while the Blue Streak® line rounds out the program with additional fitment options — together covering an enormous range of import and domestic applications. The combined Standard® and Blue Streak® Camshaft and Crankshaft Position Sensor program features nearly 1,000 SKUs covering more than 250 million vehicles. Recent crankshaft sensor additions demonstrate SMP's commitment to staying current: new crankshaft sensors have been added for heavy-duty RAM trucks through 2024, 2023–22 Kia Carnival, 2022–17 Toyota Highlander, and more.

Engineering and Manufacturing Excellence

What sets SMP crankshaft sensors apart is the depth of engineering behind each part. Camshaft and crankshaft sensors are designed and manufactured at SMP's advanced Poland and North American IATF 16949-certified facilities, where expert design centers start with the finest components while maintaining strict adherence to engineering excellence and precision manufacturing — ensuring every Standard® sensor meets or exceeds the original it's replacing.

The internal components are equally impressive. Standard® Cam and Crank Sensors feature advanced circuitry that provides immunity from electromagnetic interference for long-term accuracy, and utilize a high-strength neodymium magnet to ensure the proper signal voltage is sent to the PCM. An integrated A/D converter and digital signal processing with a dynamically adaptive switch point further improves accuracy and operation.

Rigorous Testing at Every Stage

SMP's validation process is one of the most thorough in the aftermarket. Sensors undergo three separate 48–64 hour vibration tests to ensure a long service life under the harshest conditions, chamber testing that cycles from -40°F to 257°F, and extensive end-of-line timing, pulse width, and signal-amplitude testing. Additionally, Standard® Crank Sensors feature a protective sleeve to prevent wires from chafing and creating short circuits. Matching connectors and tin-plated brass terminals ensure an accurate, watertight connection to the harness, while factory-installed grommets and wire clips ensure proper mounting during installation.

Crankshaft Sensor Kits for Complete Repairs

For situations where a sensor's connector has melted or failed alongside the sensor itself, SMP offers dedicated repair kits. These kits contain premium crankshaft sensors with a high-quality electrical connector to replace melted or damaged originals — everything a technician needs to perform the repair — and SMP offers over 20 Crankshaft Sensor Kits. This complete-repair approach saves diagnostic time and reduces the chance of a comeback caused by a compromised connector.

Broad Coverage for Import and Domestic Vehicles

With hundreds of crankshaft sensors in the line, SMP supplies comprehensive coverage for all makes, including Chrysler, Ford, GM, Honda, Mercedes-Benz, Nissan, Toyota, and Volkswagen. With over 100 years in business, Standard Motor Products is a leading independent manufacturer and distributor of premium replacement parts in the automotive aftermarket. That legacy of engineering integrity is reflected in every crankshaft position sensor that leaves the factory — a part designed not just to fit, but to perform precisely as the original intended.
