These two A-NAFTULY camshaft position sensors (part 23731JA11A) are plug-and-play replacements engineered to restore accurate camshaft timing signals on compatible Nissan and Infiniti models.

If your vehicle is showing signs of rough idling, difficult starts, engine hesitation, or a camshaft-related diagnostic trouble code, a faulty camshaft position sensor is a common cause. This twin-pack contains two direct-replacement sensors designed to match OEM mounting and connector geometry, letting you swap them in without special programming on most models. Built from industrial-grade materials, each sensor is manufactured for long life and dependable signal consistency under typical driving conditions.

• Package includes two sensors and an 18-month warranty with 24/7 customer support.

How do I confirm this is the correct replacement part?

Before purchasing, compare the part number, mounting points, connector shape, and physical dimensions to your existing sensor. Visual and numeric matches provide the highest confidence of compatibility.

• Verify OEM references such as 23731-JA11A, 23731JA11B, 237311KC1A, and other listed cross-references.
• Compare connector pin count and locking tab orientation against your vehicle’s sensor.
• When in doubt, check your vehicle’s service manual or contact support with your VIN for fitment help.
