Acura Rdx Vehicle Speed Sensor in US

The vehicle speed sensor on the Acura Rdx is a single component whose data feeds multiple vehicle systems at once on your Rdx. When it fails on the Acura Rdx, the effects appear across your Rdx speedometer, transmission, cruise control, and ABS simultaneously, making diagnosis less straightforward than a fault that affects only one system on the Acura Rdx.

Signs of a Failing Vehicle Speed Sensor on the Acura Rdx

• Speedometer on your Acura Rdx reading zero, displaying erratically, or showing an inaccurate speed
• Harsh, erratic, or delayed transmission shifting on the Rdx, the TCM uses speed data to determine shift points
• Cruise control on your Acura Rdx refuses to engage or cuts out unexpectedly during use
• ABS or traction control warning lights illuminated on the Rdx dashboard
• Check engine light on your Acura Rdx with stored codes P0500, P0501, or P0502
• Rdx transmission entering limp mode, locking into a single gear to prevent damage

Transmission-Mounted vs. Wheel-Mounted Speed Sensors on the Acura Rdx

On older Acura Rdx vehicles and most rear-wheel-drive designs, a dedicated transmission-mounted speed sensor monitors output shaft speed on the Rdx and serves as the primary reference for the Rdx speedometer and transmission control module. On modern Acura Rdx front-wheel-drive and all-wheel-drive platforms, wheel hub sensors serve the dual function of ABS speed sensing and vehicle speed data delivery on the Rdx, one sensor feeding multiple Acura Rdx systems from a single mounting point.

Why GeoBrakes for the Acura Rdx Vehicle Speed Sensor

Signal accuracy is the defining specification for a Acura Rdx vehicle speed sensor. A sensor that generates the wrong pulse frequency for your Rdx control modules produces incorrect speedometer readings, mis-timed transmission shifts, and inaccurate ABS calibration on your Acura Rdx, even if it passes a basic resistance test. Every speed sensor in the GeoBrakes catalogue is sourced to the correct signal frequency for the Acura Rdx exact year, make, model, and sensor position.

Frequently Asked Questions - Acura Rdx Vehicle Speed Sensor

Can a faulty speed sensor affect the transmission on my Acura Rdx?

Yes. The Acura Rdx transmission control module relies on vehicle speed data to calculate correct shift timing. A failed Rdx speed sensor can cause erratic shifting, delayed upshifts, incorrect downshifts, or trigger Rdx limp mode.

Will a bad vehicle speed sensor turn on the check engine light on my Acura Rdx?

Yes. A failed Acura Rdx vehicle speed sensor typically stores fault codes P0500, P0501, or P0502. Depending on the Rdx, it may also trigger ABS, traction control, or transmission warning lights simultaneously.

Is the vehicle speed sensor the same as the ABS wheel speed sensor on my Acura Rdx?

On many modern Acura Rdx vehicles, yes, wheel hub sensors serve both the ABS system and vehicle speed sensing simultaneously on your Rdx. On older Rdx vehicles with transmission-mounted speed sensors, they are separate components. Use the GeoBrakes vehicle selector to confirm the correct sensor type for your Acura Rdx.
