Mitsubishi Diamante Vehicle Speed Sensor in US

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

Signs of a Failing Vehicle Speed Sensor on the Mitsubishi Diamante

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

Transmission-Mounted vs. Wheel-Mounted Speed Sensors on the Mitsubishi Diamante

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

Why GeoBrakes for the Mitsubishi Diamante Vehicle Speed Sensor

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

Frequently Asked Questions - Mitsubishi Diamante Vehicle Speed Sensor

Can a faulty speed sensor affect the transmission on my Mitsubishi Diamante?

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

Will a bad vehicle speed sensor turn on the check engine light on my Mitsubishi Diamante?

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

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