{"product_id":"volvo-644","title":"Volvo Penta Idle Air Control Valve 3843751","description":"\u003cp\u003eVolvo Penta 3843751 is an idle air control valve used in select Volvo Penta gasoline engine applications. Based on the part naming you provided, this component is the IAC or IACV valve that helps control idle speed by regulating bypass air at low throttle openings. It is commonly referenced alongside Volvo Penta numbers \u003cstrong\u003e3843750\u003c\/strong\u003e and \u003cstrong\u003e3857696\u003c\/strong\u003e, so those related numbers should be checked carefully against the exact engine setup before ordering.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Volvo Penta idle air control valve reference \u003cstrong\u003e3843751\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCommonly identified as an \u003cstrong\u003eIAC \/ IACV idle air control valve\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eHelps regulate idle airflow for smoother low-speed engine operation\u003c\/li\u003e\n\u003cli\u003eRelated Volvo Penta reference numbers include \u003cstrong\u003e3843750\u003c\/strong\u003e and \u003cstrong\u003e3857696\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eBest matched by exact engine and throttle-body application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eEngine Compatibility\u003c\/h2\u003e\n\u003cp\u003eThis part should be treated as a \u003cstrong\u003egasoline engine idle-control component\u003c\/strong\u003e rather than a broad all-model sensor. Because IAC valves can vary by throttle-body, intake, and engine-management setup, the safest fitment path is to match \u003cstrong\u003e3843751\u003c\/strong\u003e against the exact Volvo Penta engine serial number and the correct fuel-and-air or throttle-body diagram before ordering.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eMatch Volvo Penta part number \u003cstrong\u003e3843751\u003c\/strong\u003e to your engine serial number before ordering. Idle air control valves can look similar across multiple gasoline engine packages while using different connectors, mounting patterns, or control calibrations.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eThis valve is commonly replaced when the engine has unstable idle, stalling at low RPM, hard starting at idle, surging, or idle-speed faults linked to the air-control circuit. It is also worth checking when carbon buildup, sticking, or electrical failure is suspected in the idle-control system.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eConfirm the connector style and mounting pattern before installation, and compare the removed valve carefully against the replacement part. On idle-control components, exact application matters more than a visual guess. It is also smart to inspect the throttle-body passage and gasket area during service.\u003c\/p\u003e\n\u003ch2\u003eAlternate\/Superseded Part Numbers\u003c\/h2\u003e\n\u003cp\u003eRelated Volvo Penta numbers provided with this application are:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e3843750\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e3843751\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e3857696\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThese should be treated as related reference numbers that still need exact serial-number confirmation for the specific engine.\u003c\/p\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eWith IAC valves, the easy mistake is replacing the part before confirming the exact application and connector style. Matching by serial number first usually saves time, especially when similar Volvo Penta gas-engine idle-control parts can look nearly identical on the bench.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564016140324,"sku":"3843751","price":504.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/b48fc77f-632b-499d-9c0c-655e26f9ad77.png?v=1776656697","url":"https:\/\/marisolmarine.com\/products\/volvo-644","provider":"Marisol Marine Company","version":"1.0","type":"link"}
