  Description:

  Genuine OEM Nissan Engine Control Module (ECM) — Part # 23703-9CF0A

  Replace your failed ECM with the factory-correct genuine OEM unit for the Nissan Frontier 4.0L and NV Full Size Van 4.0L. This is the same module Nissan installs at the factory — built to exact specifications for reliable engine management, fuel delivery, ignition timing, transmission control, and emissions compliance.

  Part Details:

  • Part Number: 23703-9CF0A
  • Other Names: Engine Control Module, ECM, ECU, PCM, Powertrain Control Module, Engine Computer
  • Condition: New, Genuine OEM Nissan
  • Application: 4.0L VQ40DE V6
  • Drivetrain: 2WD and 4WD Frontier; NV Full Size Van 4.0L

  ⚠️ CRITICAL — This Module Requires Programming Before Use: This is a non-programmed ECM. It cannot be installed and driven without programming. After installation, the module must be programmed to your vehicle's specific VIN by a Nissan dealership or qualified technician using a Nissan-compatible scan tool (Consult III or equivalent). This is not a plug-and-play unit. Programming is required before the vehicle will start or run correctly.

  ⚠️ Production Date Fitment Note:

  • Frontier 2WD and 4WD: to 09/2016
  • NV Full Size Van 4.0L: to 08/2015

  Always confirm your production date and exact application with your VIN before ordering.

  Compatible Vehicles:

  • 2014–2017 Nissan Frontier (4.0L VQ40DE — 2WD and 4WD, to 09/2016)
  • 2014–2015 Nissan NV Full Size Van (4.0L VQ40DE, to 08/2015)

  Always confirm fitment using your VIN before purchasing.

  Why buy OEM? Remanufactured and aftermarket ECMs are frequently flashed with generic calibrations that don't match your vehicle's specific build — causing drivability issues, incorrect fuel trim, transmission shifting problems, and failed emissions tests. The genuine Nissan ECM is factory-new with the correct base calibration for your engine and transmission combination, requiring only VIN programming — not a full reflash.

  Symptoms this part fixes:

  • Vehicle not starting or stalling immediately after start
  • Check engine light with multiple or unusual fault codes
  • Severe drivability issues — misfires, rough idle, no throttle response
  • ECM confirmed failed by dealership or qualified scan tool diagnosis
  • Water/moisture or rodent damage to the ECM
