Nissan Parts & Accessories Engine Crankshaft Position Sensor

Genuine Nissan OEM Engine Crankshaft Position Sensors

When your Nissan's engine starts misfiring, stalling unexpectedly, or refuses to start at all, a failing crankshaft position sensor is often the culprit. This small but critical component monitors the rotational speed and position of the crankshaft and relays that data to the Engine Control Module (ECM), which uses it to precisely time fuel injection and ignition. Choosing a genuine Nissan Parts & Accessories crankshaft position sensor — rather than a generic aftermarket substitute — ensures the signal characteristics, connector fitment, and internal calibration exactly match what Nissan's engineers originally specified for your vehicle.

Why OEM Matters for Crankshaft Position Sensors

The crankshaft position sensor is one of the most communication-sensitive components in the engine management system. This sensor is responsible for communicating the angle of the crankshaft to the ECM, and failing sensors can cause hard or no starts, cutting out, misfires, and reduced power. An OEM sensor from Nissan is manufactured to the same tolerances as the part originally installed on the assembly line, so signal voltage, reluctor ring compatibility, and harness connector geometry are all guaranteed to be correct — eliminating the guesswork that comes with universal-fit or remanufactured alternatives.

Backed by Nissan's warranty, crankshaft position sensors restore factory performance and keep the ECM receiving the clean, consistent crank angle data it needs to optimize combustion. This is especially important on high-revving platforms like the VQ-series V6 found in the Maxima, Murano, and 370Z, where timing precision directly impacts both power output and emissions compliance.

Broad Model Coverage Across the Nissan Lineup

Nissan's genuine crankshaft position sensor catalog spans decades of production and covers a wide range of platforms. Coverage includes popular nameplates such as the Altima, Frontier, GT-R, Maxima, Murano, Pathfinder, Rogue, Sentra, Titan, Versa, and Xterra, among many others. Whether you're maintaining a vintage 240SX or keeping a current-generation Rogue on the road, the genuine Nissan part is engineered to drop in without modification — no adapter harnesses, no signal conditioning, no compromises.

Each Nissan OEM crankshaft position sensor carries its own unique part number (such as the 23731-EA20D for certain Xterra and Pathfinder applications with the VQ40DE engine, or the 23731-1VA0A for Rogue and Cube hybrid applications) so you can always confirm an exact match before installation. Browse the full Engine Crankshaft Position Sensor category to find the right part for your specific year, model, and engine configuration.

Fit, Reliability, and Peace of Mind

One of the most common complaints about aftermarket crankshaft position sensors is intermittent signal dropout — a failure mode that produces erratic misfires and difficult-to-diagnose trouble codes. Genuine Nissan sensors are built and validated to resist heat cycling, oil contamination, and vibration over the full service life of the engine. When the repair needs to be done right the first time, an OEM Nissan crankshaft position sensor is the definitive choice for any Nissan owner or technician.
