It matches OEM reference 18.3855 (catalog number 406.3855000 \/ 406.3855000-01) and provides accurate detection of abnormal combustion, ensuring the ECU can correct ignition timing and protect the engine from damage.\u003c\/p\u003e\n\u003cp data-start=\"631\" data-end=\"1107\"\u003e\u003cstrong data-start=\"631\" data-end=\"669\"\u003eWhy choose this detonation sensor?\u003c\/strong\u003e\u003cbr data-start=\"669\" data-end=\"672\"\u003eManufactured to OEM standards by trusted suppliers such as Avtopribor Kaluga and Meat Doria, this sensor guarantees exact fit and electrical compatibility. It reliably monitors engine vibrations for signs of detonation (pinging), enabling precise ECU adjustments to maintain smooth performance, fuel efficiency, and long-term engine health. By replacing a faulty unit, you restore consistent operation and prevent costly engine wear.\u003c\/p\u003e\n\u003cp data-start=\"1109\" data-end=\"1343\"\u003e\u003cstrong data-start=\"1109\" data-end=\"1131\"\u003eTechnical details:\u003c\/strong\u003e\u003cbr data-start=\"1131\" data-end=\"1134\"\u003eMaterial: metal housing with sealed electronics and plastic connector\u003cbr data-start=\"1203\" data-end=\"1206\"\u003eDimensions: approx. 40 × 20 × 20 mm\u003cbr data-start=\"1241\" data-end=\"1244\"\u003eOEM reference: 18.3855 \/ 406.3855000 \/ 406.3855000-01\u003cbr data-start=\"1297\" data-end=\"1300\"\u003eCondition: NEW, factory-grade replacement\u003c\/p\u003e\n\u003cp data-start=\"1345\" data-end=\"1434\"\u003e\u003cstrong data-start=\"1345\" data-end=\"1367\"\u003eCompatible models:\u003c\/strong\u003e\u003cbr data-start=\"1367\" data-end=\"1370\"\u003eBukhanka Modern (2.7L)\u003cbr data-start=\"1392\" data-end=\"1395\"\u003eHunter \u0026amp; 469 (2.7L)\u003cbr data-start=\"1414\" data-end=\"1417\"\u003ePatriot\u003cbr data-start=\"1424\" data-end=\"1427\"\u003eProfi\u003c\/p\u003e\n\u003cp data-start=\"1436\" data-end=\"1845\"\u003e\u003cstrong data-start=\"1436\" data-end=\"1458\"\u003eInstallation tips:\u003c\/strong\u003e\u003cbr data-start=\"1458\" data-end=\"1461\"\u003eLocate the sensor on the engine block (commonly near the intake side or accessory drive area). Disconnect the harness plug, then unscrew the old sensor. Clean the mounting surface before installing the new unit. Tighten carefully to OEM torque to avoid cracking the housing. Reconnect the harness and verify proper operation by clearing fault codes and running an engine test cycle.\u003c\/p\u003e\n\u003cp data-start=\"1847\" data-end=\"2164\"\u003e\u003cstrong data-start=\"1847\" data-end=\"1867\"\u003eWhen to replace?\u003c\/strong\u003e\u003cbr data-start=\"1867\" data-end=\"1870\"\u003eReplace the knock sensor if fault codes appear in the ECU, if engine hesitation or pinging occurs, or if timing advance becomes unstable. Symptoms include power loss, poor fuel economy, and erratic acceleration. Sensors are typically replaced at around 100,000 km as preventative maintenance.\u003c\/p\u003e\n\u003cp data-start=\"2166\" data-end=\"2286\"\u003e\u003cstrong data-start=\"2166\" data-end=\"2194\"\u003eQuestions about fitment?\u003c\/strong\u003e\u003cbr data-start=\"2194\" data-end=\"2197\"\u003eNot sure if this part fits your vehicle?
