Overview

The Hitachi CPS0007 is a camshaft position sensor designed as a direct replacement for Nissan engines that originally used OEM part numbers 23731-4M500, 23731-4M505, 23731-4M506, 23731-4M50B, or 23731-5M005. The camshaft position sensor feeds real-time cam position data to the ECU, which uses it to sequence fuel injection and ignition timing accurately. A failed or degraded sensor typically throws P0340/P0345 codes, causes rough idle, hard starts, or poor fuel economy — all symptoms this replacement directly addresses by restoring a clean, accurate signal.

Hitachi's standing as a Tier 1 OE supplier means the CPS0007 is manufactured to the same standards as factory components — not reverse-engineered from spec sheets. The flange mount design and dual-convertible connector interface directly with the original mounting point and harness without adapters or modifications. With a body measuring just 1.52 x 1.62 x 2.32 inches, it fits the engine bay without clearance issues. This is a straightforward swap: disconnect the battery, unplug the harness, remove the single flange bolt, and install the new unit. For DIYers doing their own engine management diagnostics, this is a reliable, cost-effective fix that doesn't require sacrificing quality for price.

Pros & Cons

👍 Pros

  • Direct OEM fitment — matches the flange mount and connector geometry of Nissan factory sensors using the exact 23731-4M50x part number series.
  • Tier 1 supplier pedigree means the CPS0007 is built to the same specification as factory-installed components, not a cost-reduced aftermarket interpretation.
  • Brand new unit eliminates the reliability concerns of remanufactured sensors, which can carry latent wear from their previous service life.
  • Compact dimensions (1.52 x 1.62 x 2.32 inches) and flange mount design make for a clean, bolt-in swap with no modifications.
  • High measurement accuracy restores proper ECU cam timing data, which directly affects fuel trim, ignition timing, and idle quality.

👎 Cons

  • No wiring pigtail included — if the OEM connector is corroded or damaged, you'll need a separate repair harness, adding cost and time.
  • At 0.05 lbs, the sensor is light, but the flange mount bolt torque spec isn't documented in the listing — consult a factory service manual to avoid over-torquing the mount.
  • Vehicle-specific fitment must be verified by cross-referencing the OEM part number; the listing does not enumerate every compatible year/make/model explicitly.
  • No installation instructions included beyond basic labeling — first-timers will need a service manual or a reliable online guide for their specific application.

Frequently Asked Questions

This sensor cross-references OEM part numbers 23731-4M500, 23731-4M505, 23731-4M506, 23731-4M50B, and 23731-5M005 — verify your existing part number against this list before ordering, as Nissan used multiple variants across model years.
It is 100% new — not remanufactured or rebuilt. Hitachi is a Tier 1 OE supplier, meaning this is the same supplier tier that produces sensors for the factory line, not an aftermarket knockoff.
Difficulty is low to moderate depending on sensor location on your specific engine. Typically requires a basic socket set and a small wrench for the mounting flange bolt. Disconnect the battery before swapping, unplug the harness connector, unbolt the flange mount, and reverse the process for install.
If the code is caused by a failed or out-of-range sensor (rather than a wiring or reluctor ring issue), yes — replacing the sensor with a spec-correct unit like the CPS0007 should resolve those codes. Always check wiring and connector integrity before condemning the sensor itself.
The sensor comes as a direct drop-in replacement. Confirm whether your application requires a new pigtail connector or retaining hardware, as those are typically reused from the original install.
