Heres a possible scenario. Joe customer walks in and asks for a free scan because his CEL is on. Auto Zone person says sure and scans Joe’s car. Comes up with TPS code. AZ says, “You need a new TPS” Joe says “Cool, I’ll take it”. Joe, feeling good thinking “Wow I just fixed my car myself” defiantly puts the middle finger up and saying up yours to the dealerships and auto shops in general because its only going to cost him whatever the price of the TPS is. Joe pays lets say $200 for a TPS then goes home and installs it. Feeling rather good about his new found auto electric skills, Joe goes on test drive when all of a sudden, BAM, CEL is back on. Joe goes back to AZ and tells AZ person "This thing didnt work, I want my $200 back. AZ person says “Sorry, no returns on electrical items”. See where I’m going with this?? Now Joe has to go to a shop, remember, the ones he just defiantly put his middle finger up at?? Pays $500 to have the wiring to the TPS traced and repaired. He now takes AZ to court for his $200 plus whatever else he can get because that guy sold him the wrong part.
