Light came on at 41000 miles, then turned itself off after a couple of days (approx 300 miles). Same has occurred 3 more times, at the last my Previa (2002) was in for a service (70000 miles) when the light was on, and the main dealer said that the code was indicating a fault with the catalyst. They reset the light and said that if it comes on again they will upgrade the ECU (apply software update). The light is now on again - I am waiting to see if it goes out soon!

Cheers, Rob

Well the light has finally gone out after 2 weeks (I was on the point of booking the car in at a main dealer - for a possible ECU software upgrade). In that two weeks the car has done about 700 miles. I live in a rural location and normally each trip is a minimum of 10 miles, and the car is used ever day.

Hope this information is of interest.

Guess what, the light came back on again yesterday. Just driving along on a straight level road at about 55mph.

Very odd.

Will wait and see if it goes out again, otherwise a trip to the main dealer.
