Does anyone know exactly what an error code of P1121 on a 2004 Prius means? It must be related to the check engine light.
An update on my Prius, which is STILL in the shop. A VERY helpful fellow on the Prius toll free number, checked into it, and found that's actually a engine valve sensor error. Not actually an engine problem at least, but I sure wish Toyota would get these sensors to work correctly, as this is now the 2nd sensor that is having to be replaced.
