I bought a salvaged title 2001 toyota tundra a couple of yers ago and it has been a great truck. My engine light has been on for some time and at first, garages that had mdiocore scanners could only tell me it was an emmissions problem. Recently I had a garage that had a very expensive scanner and hooked it up to my toy and it indicated the O-2 Sensor (#1/#1 Bank) was bad. This is the sensor that is on the drivers side coming off the exhaust manifold pipe. I checked the price and it is expensive, around $102.00. I am just wondering since this is probably what has caused my engine light to stay on all this time and when I got the truck it only had 35k miles,but I am concerned if I replace it and the same thing happens again, what could be casuing it. This truck is like new and no leaks anywhere. As a matter of fact even around the sensor it is still clean and shiney. Any thoughts?
