Our Nitrous Oxide Sensors are fabricated using the same genuine VDO components, control chips, circuit boards, and wire harnesses. Built to the highest standards for long-lasting high performance and extensively tested under strict quality control processes. 1-Year Exchange Warranty Our NOx Sensors are backed by a full 1-year warranty from the date of purchase. If you experience any factory defects or workmanship issues, well provide a quick and hassle-free exchange. This warranty covers the cost of the pact us for a replacement. NOx sensors monitor Nitrogen Oxide levels in exhaust systems. Two sensors are typically used, one upstream and one downstream to assess Selective Catalytic Reduction System SCR efficiency. The ECU uses the readings to regulate DEF injection. Inferior sensors result in problems like weak acceleration, idling jitter, combustion issues, or failure to start. Choose OE quality sensors to avoid these complications.
