{"product_id":"volvo-757","title":"Volvo Penta Throttle Position Sensor 3857487","description":"\u003cp\u003eVolvo Penta 3857487 is a throttle position sensor used in select Volvo Penta gasoline engine applications. This sensor monitors throttle angle and sends that signal to the engine management system to support proper idle response, throttle transition, and overall engine performance. It is best matched by exact engine serial number and throttle-body application rather than by appearance alone.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Volvo Penta throttle position sensor reference \u003cstrong\u003e3857487\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMeasures throttle position for engine management input\u003c\/li\u003e\n\u003cli\u003eSupports smooth throttle response and stable engine operation\u003c\/li\u003e\n\u003cli\u003eUsed on select Volvo Penta gasoline fuel-injected applications\u003c\/li\u003e\n\u003cli\u003eBest matched by exact throttle-body and serial-number-based fitment\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 throttle-body sensor\u003c\/strong\u003e rather than a broad all-model sensor. Throttle position sensors can vary by engine family, throttle-body design, and engine control system, so the safest fitment path is to match \u003cstrong\u003e3857487\u003c\/strong\u003e to the exact Volvo Penta engine diagram and serial-number-based application before ordering.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eMatch Volvo Penta part number \u003cstrong\u003e3857487\u003c\/strong\u003e to your engine serial number before ordering. Throttle position sensors may look similar across multiple Volvo Penta gas-engine packages while using different connectors, mounting patterns, or calibrations.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eThis sensor is commonly replaced when the engine shows poor throttle response, unstable idle, hesitation, surging, or fault symptoms related to throttle-position input. It is also worth checking when diagnosing intermittent fuel-injection or idle-control issues on the throttle body.\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 sensor carefully against the replacement part. On throttle-position sensors, exact application matters more than a visual guess. It is also smart to inspect the throttle-body linkage and connector condition during service.\u003c\/p\u003e\n\u003ch2\u003eAlternate\/Superseded Part Numbers\u003c\/h2\u003e\n\u003cp\u003eUse \u003cstrong\u003e3857487\u003c\/strong\u003e as the core OEM reference and confirm any related numbers against the exact serial-number-based parts diagram before ordering. Throttle-body sensors are one of the parts where a close-looking number can still point to a different calibration or mounting style.\u003c\/p\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eWith throttle position sensors, the easy mistake is ordering by engine family alone. Matching the exact throttle body and connector style first usually saves time, especially on Volvo Penta gasoline engines where similar sensors can look almost 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":43564032426020,"sku":"3857487","price":257.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/5c4a5a24-c6ff-482b-af69-47ef8bed070d.png?v=1776658119","url":"https:\/\/marisolmarine.com\/products\/volvo-757","provider":"Marisol Marine Company","version":"1.0","type":"link"}
