21906701 Module | Genuine Volvo Penta Part

🔧 Product Description

Engine-control module calibrated for selected Volvo Penta 5.7-litre / V8-270-C petrol applications. It manages sequential injection, ignition timing, diagnostics and engine-protection functions.

🚤 Compatibility

Typically suits:

• Volvo Penta V8-270-C-A

• Engine Family: V
• HP Range: 270 HP

⚙️ Key Features

• Engine control module from the Ignition and Control Systems group
• 0.925 kg
• Supersedes 21652642 and 21461925
• One listed application, so the calibration is model specific

🔌 Function

Controls fuel and spark events, monitors sensors and communicates faults/operating data to the control system.

⚠️ Common Signs of Failure

• Engine cranks but will not fire, or cuts out without warning
• Repeated or intermittent fault codes with no matching sensor fault behind them
• Rough running, misfire or a hunting idle that no tune-up cures
• Loss of communication between the module and the helm display or diagnostic tool
• Corroded connector pins, water tracking or swollen potting found when the unit is opened

🛠️ Service Notes

• Confirm battery voltage, earths and connector condition before condemning the module; a poor earth or a corroded pin produces the same symptoms
• It replaces 21652642 and 21461925, so both older numbers are covered by this one
• A replacement module has to be matched and programmed to the engine before the boat will run
