Keep the sensor talking to your vehicle's electronics with the Standard Ignition Mass Air Flow Sensor Connector / Nitrogen Oxide (NOx) Sensor Connector (S2891) — the harness-side electrical connector that links the sensor to the wiring. This part is listed under both names. It's a direct-fit replacement for the listed applications: 2012-2013 Chrysler 300, 2011-2013 Jeep Grand Cherokee, 2014-2017 Ram 2500, 2011-2012 and 2015-2017 Ram 3500, 2011-2012 and 2015-2017 Ram 4500, and 2011-2012 and 2016-2017 Ram 5500.
Purpose: Provides the plug-in electrical connection between the mass air flow / NOx sensor and the vehicle harness, carrying the sensor's signal and power leads.
Signs it may need replacing: Melted, corroded, or damaged terminals, an intermittent connection, or a stored sensor-related trouble code. If a failed connector is the cause, this replaces the original.
Fresh connection: Installs in place of the worn or broken original connector to re-establish a secure contact.
Diagnose the cause of the fault before replacing, as sensor codes can have other sources. Manufacturer part number S2891.
Frequently Asked Questions
What does the S2891 connector do?
It's the harness-side electrical connector that links the mass air flow / NOx sensor to your vehicle's wiring, carrying the sensor's signal and power leads.
Why is it listed under two part-type names?
This part is cataloged as both a Mass Air Flow Sensor Connector and a Nitrogen Oxide (NOx) Sensor Connector, so it appears under both names.
Which vehicles does it fit?
It's a direct-fit replacement for the 2012-2013 Chrysler 300, 2011-2013 Jeep Grand Cherokee, 2014-2017 Ram 2500, and 2011-2012/2015-2017 Ram 3500, 4500, and 5500. See the Buyer's Guide tab.
When should I replace the connector?
Consider replacement if the terminals are melted, corroded, or damaged, or if you have an intermittent connection or a stored sensor code. Diagnose the cause first.
Will this fix my sensor trouble code?
If a failed connector is the cause of the fault, replacing it addresses that. Sensor codes can have other sources, so confirm the diagnosis before replacing parts.
