Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for using just answer.
A couple questions for you first....
Take a look at the emission control label under the hood of your car and read it (square white stacker), there should be some notations on this label indicating weither your car complies with Federal or California emissions....which one do you have?
Question 2- do you have code #'s stored for a specific failure....specific sensor you need to replace or what exactly do you have going on here?
I look forward to your prompt reply so that I may assist you. Thanks!
Thanks, I'll try again next week.
I am afraid I don't have the code #s.The mechanic that did the diagnostics and gave me the estimate just wrote that both front sensors needed to be replaced. He quoted $460 for the parts and $200 labor. I trust that he has given me the right diagnosis. My question was where are they located and is this too difficult for a non-professional to attempt. I can get the parts from Toyota for $330 (less online) so I am just trying to find out if it is worth trying to save $330 by getting my neighbor to help me replace them myself.
If you are confident in his diagnosis (however almost unheard of that BOTH sensors fail at once) then yes proceed. THis is an easy 10 minute job and well worth the savings. Take a look at www.metrotoyotapartsnow.com to see if the sensors are any cheaper there.
The bank 2 sensor 1 o2 sensor is VERY easy to get to, its on the exhaust manifold near the radiator and can be removed using an o2 sensor socket, a 7/8" wrench or a 22mm wrench. It's better to do this with the engine HOT to avoid possible issues with the sensor cross threading or seizing in the manifold, a can of wd-40 or PB blaster is also a god idea to hav on hand to help lubricate the threads as you remove the sensor. The bank 1 sensor 1 is a little more challenging to get to, it's in the same location but on the REAR exhuast manifold, you access this one by reaching down from the top behind the intake manifold.
Thanks. I was pretty sure I had the bank 2 sensor identified but that just seemed too easy. You confirmed my suspicions about the bank 1 sensor. Is it more easily accessed from underneath? One last thing and I'll let you go. If I can get my hands on the codes is there a code(s) that identifies a specific sensor since you (like me) question two independent electrical/electronic parts going out simultaneously?
