The original listing names them as \"Senna Vasa 2014\", which we read as the Sienna and the Venza. The photos show a sensor with a threaded body, a black sleeved lead and a grey four-pin plug. Easy Life Markets sells it as a single sensor. The supplier gives no part number, so please use the checks further down this page before you order.\u003c\/p\u003e\n\n\u003cp\u003eThe front sensor is the one that matters most to how the engine runs. It sits in the exhaust ahead of the catalytic converter and tells the engine computer how much oxygen is left after combustion. The computer uses that signal to trim the fuel mixture many times a second. When the sensor slows down or fails, the engine can run rich or lean, fuel use goes up and the check engine light comes on.

A V6 engine has two banks and each has its own front sensor, and the two are often different parts with different lead lengths.

A sensor comes out of a warm manifold more easily than a cold one, but exhaust parts burn.\u003c\/li\u003e\n\u003cli\u003eUnplug the connector first, then use an oxygen sensor socket with a slot for the lead.\u003c\/li\u003e\n\u003cli\u003eIf the old sensor is tight, soak the threads with penetrating oil and give it time. Forcing it can strip the threads in the manifold.\u003c\/li\u003e\n\u003cli\u003eCheck whether the new sensor's threads arrive coated. If they are bare, use a small amount of sensor-safe anti-seize on the threads only, and keep it off the tip.\u003c\/li\u003e\n\u003cli\u003eTighten to the figure in the service manual, route the lead exactly as the original ran and clip it away from the exhaust.\u003c\/li\u003e\n\u003cli\u003eClear the fault codes and drive the car through a full warm-up so the computer can relearn.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAccess to the rear-bank sensor on a transverse V6 is tight. Many owners leave that one to a workshop.\u003c\/p\u003e\n\n\u003ch2\u003eLooking After the New Sensor\u003c\/h2\u003e\n\u003cp\u003eOxygen sensors are damaged by contamination more than by age. Coolant leaking into a cylinder, an engine that burns oil, and silicone sealant used near the intake or exhaust will all coat the sensor tip and shorten its life. If your old sensor came out with a white, glazed or oily tip, find the cause before fitting a new one.\u003c\/p\u003e\n\n\u003ch2\u003eWho This Sensor Is For\u003c\/h2\u003e\n\u003cp\u003eOwners and garages working on a 2014 Toyota Sienna or Venza who have compared the plug and the lead with the original and, ideally, checked the part number with us first.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eIs this a genuine Toyota sensor?\u003c\/strong\u003e No. It is an unbranded aftermarket sensor.
