Lexus RX300 P0500 Fault: Speedometer and Odometer Not Working with ABS Light On
I own a 2000 Lexus RX300 and am experiencing a serious issue: both the speedometer and odometer have stopped working. After taking the vehicle to a mechanic, they scanned it and found fault code P0500 — indicating a problem with the Vehicle Speed Sensor (VSS). The technician replaced the upper speed sensor units (Sensor 1 and 2), but the issue persists. Additionally, both the Check Engine light and ABS light remain on. I'm now wondering what other potential causes could be responsible for this failure, especially since the sensors were replaced. Could the problem lie in wiring, PCM calibration, or another component? Any advice or troubleshooting steps would be greatly appreciated.
A P0500 code typically indicates one of the following issues: - The Vehicle Speed Sensor (VSS) is not functioning properly - There is a damaged or frayed wire connected to the VSS - The Powertrain Control Module (PCM) is incorrectly configured for the actual tire size installed on the vehicle For more details, refer to official P0500 diagnostic information.
