The above Toyota Service Bulletin was issued in May 2005, as you can see it not only affects the Previa but a lot of other models as well. The fact Toyota issued this bulletin proves that they knew there was a problem, yet only last month Toyota GB Customer Services denied any knowledge of it! A faulty batch of catalytic converters fitted to the Toyota range means they are not fit for purpose and under the Sale of Goods Act you can take the retailer to court if this fault occurs within 6 years of purchase. A new cat will cost between £1200-1400, making a claim through the small claims court will cost £60-70 and can be done on-line at www.moneyclaim.gov.uk/csmco2/index.jsp Make sure you read the leaflets, or even better make an appoinment with your local Trading Standards Office. The bulletin goes on to state;

"If, based on the sensor signals, you judge catalyst is not working properly, replace catalyst and not the O2 sensors".
