Lexus Is300 Vehicle Speed Sensor in US

The vehicle speed sensor on the Lexus Is300 is a single component whose data feeds multiple vehicle systems at once on your Is300. When it fails on the Lexus Is300, the effects appear across your Is300 speedometer, transmission, cruise control, and ABS simultaneously, making diagnosis less straightforward than a fault that affects only one system on the Lexus Is300.

Signs of a Failing Vehicle Speed Sensor on the Lexus Is300

• Speedometer on your Lexus Is300 reading zero, displaying erratically, or showing an inaccurate speed
• Harsh, erratic, or delayed transmission shifting on the Is300, the TCM uses speed data to determine shift points
• Cruise control on your Lexus Is300 refuses to engage or cuts out unexpectedly during use
• ABS or traction control warning lights illuminated on the Is300 dashboard
• Check engine light on your Lexus Is300 with stored codes P0500, P0501, or P0502
• Is300 transmission entering limp mode, locking into a single gear to prevent damage

Transmission-Mounted vs. Wheel-Mounted Speed Sensors on the Lexus Is300

On older Lexus Is300 vehicles and most rear-wheel-drive designs, a dedicated transmission-mounted speed sensor monitors output shaft speed on the Is300 and serves as the primary reference for the Is300 speedometer and transmission control module. On modern Lexus Is300 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 Is300, one sensor feeding multiple Lexus Is300 systems from a single mounting point.

Why GeoBrakes for the Lexus Is300 Vehicle Speed Sensor

Signal accuracy is the defining specification for a Lexus Is300 vehicle speed sensor. A sensor that generates the wrong pulse frequency for your Is300 control modules produces incorrect speedometer readings, mis-timed transmission shifts, and inaccurate ABS calibration on your Lexus Is300, even if it passes a basic resistance test. Every speed sensor in the GeoBrakes catalogue is sourced to the correct signal frequency for the Lexus Is300 exact year, make, model, and sensor position.

Frequently Asked Questions - Lexus Is300 Vehicle Speed Sensor

Can a faulty speed sensor affect the transmission on my Lexus Is300?

Yes. The Lexus Is300 transmission control module relies on vehicle speed data to calculate correct shift timing. A failed Is300 speed sensor can cause erratic shifting, delayed upshifts, incorrect downshifts, or trigger Is300 limp mode.

Will a bad vehicle speed sensor turn on the check engine light on my Lexus Is300?

Yes. A failed Lexus Is300 vehicle speed sensor typically stores fault codes P0500, P0501, or P0502. Depending on the Is300, 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 Lexus Is300?

On many modern Lexus Is300 vehicles, yes, wheel hub sensors serve both the ABS system and vehicle speed sensing simultaneously on your Is300. On older Is300 vehicles with transmission-mounted speed sensors, they are separate components. Use the GeoBrakes vehicle selector to confirm the correct sensor type for your Lexus Is300.
