Please Keep In Mind That A Code Is Not Telling You What Part To Replace.

Chances are that you need a new sensor . . . , but that may not fix the problem. The problem can be in the sensor circuit or something else. The code tells you where to begin testing.

There are lots of parts replaced unnecessarily by putting in parts that were ordered up by doctors like Car MD. Does the information that came with your reader really say to replace a part whenever you get a code? I find that really hard to believe.

Could you post for us what the accompanying information says to do after obtaining a fault code?

You can get some after-market parts prices from Autozone or Advance, etcetera, online.

Thanks, CSA

The Dealer Or Independent Technician Will Probably Check And Verify That The Circuit Or The Part Is At Fault Before Replacing It.

Since labor prices and part prices vary from place to place, it would be best for you to call a couple of places and ask about approximate repair costs. You can call a local Dealer, Autozone or Advance Auto Parts, etcetera if you are curious about the price of the part. They also may be able to tell you if it’s an easy repair on that Rav 4.
