P0500 - Toyota Yaris Forums

Frankieo · 07-25-2010, 12:44 AM

I was driving my 2007 Yaris and notice the engine light pop up. The idle change it was riding a little rough almost like it wanted to shut off. The Transmission wouldn't want to go into fourth gear. The cruse control was also not working. I took it to the nearest auto zone and had them scan my car and the computer gave me a P0500 code. The speedometer works fine. Do you guys know where I should look? I've been looking at the repair manual and it talks to test the ECM but I was hoping someone else has ran into this situation before I start messing with that.

A code P0500 may mean that one or more of the following has happened:

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

Do you know what the vss looks like on the trans so I can test the wires going into it.
