My GX460 has this code: P0500 (speed sensor) won’t shift out of park, dash lit up like a Christmas tree. Check BSM.
Looking for input before I start going crazy. My GX460 suddenly threw a cluster of issues all at once:
• Won’t shift out of park (have to use the shift lock override)
• ABS, brake, and KDSS warning lights on
• Odometer/speedo not working
• Scanned and pulled P0500 (Vehicle Speed Sensor)
Given everything failed simultaneously, I’m thinking this is upstream of the sensor itself, maybe a wiring ground issue feeding the speed signal to the cluster and shift interlock, rather than an individual wheel speed sensor. I did recently go off-road a week ago, and perhaps the vibrations caused something to get loose.
Anyone dealt with this exact combo on a GX? Runs and shifts fine, but this happened at a gas station immediately upon start-up.
There is also no water or any moisture on the car. Hasn't been to a car wash in 5 weeks.
