Installation Notes and Tips

Verify the connector shape, terminal count, and attachment method before installation. AX149 uses a female square plug-in connector with two male blade terminals and no wiring harness, so the existing vehicle connector should be inspected for corrosion, looseness, or heat damage before the new sensor is installed. Confirm the vehicle is a 2007-2009 Acura RDX and compare the original sensor location and mounting style to the replacement part.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and sensor components, and AX149 is cataloged for the listed Acura RDX applications. Always confirm fitment against the vehicle’s original part number and connector configuration before final installation.
