🔧 Product Description

Genuine Volvo Penta 1500 mm pre-NOx extension harness, weighing 0.202 kg and listed for 33 applications across D, TAD, TWD and TADH series engines. It consolidates seven earlier harnesses, so one part now covers what were separate looms. Three lengths serve this run, so measure the routing.

🚤 Compatibility

  • Engine Family: D, TAD, TWD, TADH

Full model list at the end of this description.

⚙️ Key Features

  • 1500 mm long
  • Pre-NOx extension harness
  • 0.202 kg
  • Consolidates seven earlier harnesses
  • Listed for 33 applications across D, TAD, TWD and TADH series engines
  • L=1500mm / L=2000mm (Volvo assembly listing)

🔌 Function

Extends the pre-NOx sensor connection back to its control point, so the sensor can be sited where the exhaust run requires without splicing the main loom.

⚠️ Common Signs of Failure

  • Sensor faults or lost readings that come and go with vibration
  • Connector pins corroded or pushed back in the housing
  • Insulation chafed where the extension crosses a bracket or edge
  • Sheath hardened or cracked near the exhaust
  • Locking latch broken so a plug backs off

🛠️ Service Notes

  • Three lengths serve this run at 1500, 3000 and 6000 mm - measure the routing before ordering
  • One part now covers what were seven separate looms, so an older parts list may show a different number for the same position
  • Route the extension clear of the exhaust and clip it properly, since heat and chafe are what kill these
