As part of the emissions control system, it measures exhaust conditions after treatment so the vehicle can monitor NOx output and system performance. The connector design uses one female plug with a rectangular and oval shape, plus four male pin terminals for the electrical interface. Standard Ignition NOX056 is also referenced by DNX056 and DNX503.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a failed downstream NOx sensor\u003c\/li\u003e\n\u003cli\u003eRestoring emissions system monitoring accuracy\u003c\/li\u003e\n\u003cli\u003eAddressing sensor-related fault codes\u003c\/li\u003e\n\u003cli\u003eCorrecting connector or terminal interface issues\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the downstream location and connector style before installation.
