{"product_id":"engine-coolant-temperature-sensor-448","title":"Engine Coolant Temperature Sensor","description":"The VDO 62161360870 is an engine coolant temperature (ECT) sensor, crucial for accurately monitoring your BMW's operating temperature. This sensor is installed in the engine's coolant passage and functions by changing its electrical resistance in response to temperature fluctuations. The data it sends to the Engine Control Unit (ECU) is vital for managing air-fuel mixture, ignition timing, the dashboard temperature gauge, and the operation of cooling fans. Proper functioning of the ECT sensor ensures optimal engine performance and fuel efficiency.\n\nA failing ECT sensor can manifest in several ways, including unpredictable or consistently inaccurate temperature gauge readings, which might indicate either a faulty sensor or thermostat; issues with running too rich, characterized by black, sooty exhaust and a low temperature gauge reading even when the engine is at operating temperature; or non-linear, suspicious live data output from the sensor when monitored with an OBDII scanner. These symptoms suggest the sensor is not accurately communicating the engine's thermal status to the ECU, potentially leading to suboptimal performance or diagnostic trouble codes.\n\nThis specific part is listed as a Genuine BMW part with OE number 62161360870. While the brand VDO is listed, it is also associated with Siemens VDO, a known OEM manufacturer for BMW. It is manufactured in the Czech Republic. The product information indicates it is part of the BMW instrument cluster system and is essential for displayed information. It is recommended to replace the coolant temperature sensor and thermostat together when servicing the cooling system to ensure the best probability of success.\n\nThis part has specific fitment for various BMW E23, E24, and E28 models, including the 733i, 735i, 630CSi, 633CSi, 535i, and M5 with specific engine displacements. It is advised to use a vehicle selector to confirm precise fitment.","brand":"FAE","offers":[{"title":"Default Title","offer_id":52689632887096,"sku":"62161360870","price":132.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687760895.jpg?v=1784908378","url":"https:\/\/store.motormia.co\/products\/engine-coolant-temperature-sensor-448","provider":"MOTORMIA","version":"1.0","type":"link"}
