Saturn Aura Vehicle Speed Sensor in US

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

Signs of a Failing Vehicle Speed Sensor on the Saturn Aura

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

Transmission-Mounted vs. Wheel-Mounted Speed Sensors on the Saturn Aura

On older Saturn Aura vehicles and most rear-wheel-drive designs, a dedicated transmission-mounted speed sensor monitors output shaft speed on the Aura and serves as the primary reference for the Aura speedometer and transmission control module. On modern Saturn Aura 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 Aura, one sensor feeding multiple Saturn Aura systems from a single mounting point.

Why GeoBrakes for the Saturn Aura Vehicle Speed Sensor

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

Frequently Asked Questions - Saturn Aura Vehicle Speed Sensor

Can a faulty speed sensor affect the transmission on my Saturn Aura?

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

Will a bad vehicle speed sensor turn on the check engine light on my Saturn Aura?

Yes. A failed Saturn Aura vehicle speed sensor typically stores fault codes P0500, P0501, or P0502. Depending on the Aura, 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 Saturn Aura?

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