DENSO Auto Parts 234-4490 sensor for the 2011-2014 Ford F-150 3.5L / 3.7L and other vehicles is a downstream, direct-fit unit, also called an oxygen sensor, that reads the oxygen in the exhaust and sends that signal to the engine computer.
A failing sensor can show up as a check engine light or a change in fuel economy, though several other faults produce similar symptoms. Before you replace it, look over the wire and connector for cracked or burned insulation with the engine and exhaust cool. A shop can test the signal itself.
The vehicles it fits include the 2013-2015 Ford Explorer 3.5L and the 2011-2014 Ford Mustang 3.7L / 5.0L. Quantity depends on the application, and the vehicles named here each take two, so order two and install them together. Open the Buyer's Guide tab to check your exact model and engine.
