It will not diagnose the problem for you. It will (or should) tell you about the torqe converter clutch.īut all the code will tell you is that this or that system has a fault. It won't tell you about the air conditioner. In purchasing one of those simple code readers, the OP is advised to keep in mind that on all cars that reader only sees engine specific codes that set when something happens in the system that could affect emissions. They aren't cheap either.Īlso, YOU Toyota might have been very good to you over the years, but like any machine, they can and do have issues. If you catalytic converter goes bad on you '86 Toyota, you will be the one paying for a new one. There's a LOT more stuff to go wrong now. And they don't make them like they used to. You could buy a 1986 Toyota like mine, where the light has never come on in 29 years and it has always passed tailpipe tests by a large margin. I can't read the government's PDF but it appears that from 1995 forward, exhaust catalysts and sensors are warranteed for the life of the car. €œnihil novum nihil varium nihil quod non semel spectasse sufficiat†I have to put a new muffler and pipe soon, but passed inspection and there is no leak. I can say the same for the independent, it was my choice to do the evap issue one by one I'm satisfied the dealer is honest and efficient. to look, but for me I not going to do the job anyway, I just don't want to get "cheated". If I had taken it to the dealer it would have been the cost/labor for the one sensor not five. All to no avail, it was the tank sensor the hardest and last one to check. His reader could not lift detail codes on the evap system so he systematically replaced all sensors. Some four years ago I went through a round of check engine light and had an independent work on it. Again, I would have had to reprogram the ECU as well as order it so it was the dealers job. I had the dealer put a refurbished ECU as the OEM is obsolete. Late last fall had an issue, seems a port on the ECU went open. I do not climb under cars anymore so I had no problem with the cost. Seems the cat was wore out, nearly $900 for the job. I was going to read the codes two weeks ago but decided not to and took the car in. The mini cd with the software is for windows. However, I'm getting the correct mpg for the car as is.īoth ECU port adapters came from ebay, cheap and fast. The laptop has a 12volt adapter, so I could drive and tweek. I bought a second one that is bluetooth but I have to reload xp and turn on the blue tooth adapter, a later project. If I subscribe to the advanced software I can read and change anything. I found some Linux based software to support it for free.
