I have a 2001 Rav4. I was getting 2 codes indicating that the Oxygen, Air/Fuel, MAF sensors were bad. All have been replaced, however they other codes would come about. I was informed that they determined that it was a bad computer. I gave them the authorization to replace the computer however they came up with a dozen more codes after replacing the computer. I was not informed that I was obligated to pay for the board whether it fixes the codes or not. Is there anyway out of this $1,100 dollar dilemma?
