Query: Money Saver

A Toyota dealership wanted $465 to replace a heated oxygen sensor on my 2001 Tundra pick up truck. I bought the Chilton book for $20, the sensor for $71 and replacement hardware for $8. Chiltons had great diagrams and instructions. I saved $369 and completed the job in only 30 minutes. It is a great book.Toyota Tundra/Sequoia, 2000-2006 (Chilton's Total Car Care Repair Manual)
