I have been told I need to replace both oxygen sensors. I found this out after the check engine light came on and took the truck into the local dealer. The dealer has indicated the rplacement will be $545 dollar but if they have seized up the cost will be an additional $1700 if both are seized and half this cost if only one has seized. They did say that neither may have be seized. Does this sound right?

What is the code or codes, then I can tell you. I have yet to see a Toyota Oxygen Sensor seize in over 22 years of working on them, ever. I don't know why you need sensors, they usually go out 1 at a time.
