Keep your engine control module reading intake-air moisture accurately with the Standard Ignition Humidity Sensor AX519. A humidity sensor measures the moisture content of the air and reports it to the vehicle's engine control module, which factors that reading into how it manages combustion and emissions. It installs as a direct-fit replacement for the listed applications, including the 2014-2023 Chrysler 300, 2015-2023 Dodge Challenger, 2014-2023 Jeep Cherokee and 2014-2019 Ram 1500.
Signs the original sensor may need replacing can include a stored humidity-sensor fault code or an illuminated check-engine light. Diagnose the cause before replacing, since these symptoms can have other sources; if a failed humidity sensor is the cause, this AX519 replaces it.
