Good day all!
I really need some advice!
When my 2012 Toyota Camry (3.5L V6) started using a lot more fuel than normal, I took it to a mechanic who found code P1135, which according to him means that there is a problem with something called an AIR/FUEL RATIO sensor. I wanted a second opinion due to the high price this mechanic asked to fix the problem, but the next person who looked at my car said there was something wrong with the oxygen sensors.
The second mechanic asked about half of what the first one did to replace the part, but after the sensor replacement the engine light stays on, I use even more fuel, and the engine has lost some power too. When I took the car back to the second mechanic, he said I was driving the car wrong, which is why it is using so much fuel. I know nothing about car repairs, but a friend told me that air/fuel sensors and oxygen sensors are not the same, and that maybe the second mechanic had installed the wrong type of sensor.
Can this happen, and what is the difference between the two types of sensors? Can anyone here help me out with some advice?
