2003 Toyota Highlander Q&A

2003 Toyota Highlander Question: O2 Sensors

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. -
Answer 1
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. Roy -

What type of shop should I look for? I haven't been too successful so far. ;) -
Comment 2
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. Roy -

The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine...
