O2 Sensors

(2003 Toyota Highlander)
in Nashville, TN on May 18, 2011
The mechanic indicated that two O2 sensors...both upstream...needed replacing. I was told only a dealer would be able to reset it so I would need to go to a Toyota dealer. I am told by more than one dealer that the cost would be $700+ tax...$430 for parts. Is there not a cheaper way? The dash lights won't go off so I won't be able to pass the emissions test to renew my license plates unless something is done.

it is very odd that both upstream sensors failed at the same time.

i would get a second opinion before taking this on.

the sensors are expensive because they are air fuel ratio sensors, not a common o2 sensor.

And no, you do not have to go to the dealer to re set. you definitely need another shop to re check the diag for you.

What type of shop should I look for? I haven't been too successful so far. ;)

try our locator tab at the top of the page for a list of shops in your area. you are looking for a shop that works with diags a lot. ask a lot of questions before you make your visits.
