2001 Toyota 4runner - Which wheel is causing "P0500 - Vehicle Speed Sensor A"?

Question

My 4runner is getting "P0500 - Vehicle Speed Sensor A". What does the "A" mean? Which wheel is that?

Answer 1

This has to do with the main vehicle speed sensor (VSS), not the wheel speed sensors. It's a generic code from the P050x series. The other P050x codes are specific issues.

Symptoms of a P0500 DTC may include:

• Loss of anti-lock brakes the "anti-lock" or "brake"
• Warning lamps on the dash may be lit
• The speedometer or odometer may not work properly (or at all)
• Your vehicle's RPM limiter may be decreased
• The shifting of an automatic transmission may become erratic
• Other symptoms may also be present

Things which might be at issue are:

• The Vehicle Speed Sensor (VSS) is not reading (functioning) properly
• There is a broken/frayed wire leading to the vehicle speed sensor
• The vehicle's PCM is not correctly configured for the actual tire size on the vehicle
