  • Application: 5.0L V8 Cummins ISV5.0 Diesel — Titan XD only

  ⚠️ Diesel & Model-Specific Note: This sensor is specific to the Titan XD 5.0L Cummins diesel only. It does not fit the standard Titan with the 5.6L V8 gasoline engine. Always confirm your engine and model with your VIN before ordering.

  Compatible Vehicles:

  • 2016–2019 Nissan Titan XD (5.0L Cummins ISV5.0 Diesel — A61 platform)

  Always confirm fitment using your VIN before purchasing.

  Why buy OEM? The turbo speed sensor on the ISV5.0 Cummins communicates directly with the ECM to regulate variable geometry turbocharger (VGT) vane position and monitor for turbocharger overspeeding. Aftermarket sensors for this application are virtually nonexistent and any substitute risks incorrect signal output that causes erratic boost behavior, turbocharger fault codes, or reduced engine protection. The genuine Nissan/Cummins-spec sensor is the only unit calibrated to the Titan XD's ECM parameters.

  Symptoms this part fixes:

  • Check engine light with turbocharger speed or boost sensor fault codes
  • Reduced engine power or limp mode related to turbocharger monitoring
  • Erratic boost pressure — overboost or underboost conditions
  • Turbocharger warning or diesel exhaust fluid (DEF) related fault cascades
  • Sensor confirmed failed by dealership or Cummins-compatible diagnostic tool
