21906710 Module | Genuine Volvo Penta Part

🔧 Product Description

Calibration-specific electronic engine-control module for Volvo Penta petrol V8 ignition, fuel and EVC functions. The module must match the exact engine rating, emissions configuration and software/calibration; adjacent module part numbers are not interchangeable.

🚤 Compatibility

Typically suits:

• Volvo Penta V8-320-CE-A

• Engine Family: V
• HP Range: 320 HP

⚙️ Key Features

• Engine control module from the Ignition and Control Systems group
• 0.916 kg
• Supersedes 21461929
• Shares its published weight with module 21906705, so the two cannot be told apart by mass; order by part number

🔌 Function

Controls fuel injection, ignition timing, engine protection and EVC/diagnostic communication.

⚠️ Common Signs of Failure

• Engine will not start, or stops without warning while running
• Repeat fault codes with no matching sensor or wiring fault
• Rough idle, misfire or surging under load
• Loss of communication with the helm display or diagnostic tool
• Water ingress or corroded pins found in the module connector

🛠️ Service Notes

• It replaces 21461929, so the older number is covered by this one
• Prove the wiring and earths before fitting a module; the symptoms overlap almost completely
• Module 21906705 carries the same published weight but a different calibration, so never substitute one for the other
