What Owners Say
"We had to replace the catalytic converter. It triggered an engine code."
Anonymous, WI (2006 Toyota Sienna LE 3.3-L V6)"The idiot lights indicate engine problems and the resulting codes indicate problems with the catalytic converters. The problem(s) might be in the sensors or in the converters themselves. The gas mileage is also very poor and the engine runs a little better on mid level gas. Catalytic converters (2 or 3) are too expensive to replace. The problem(s) have not been resolved."
