Where's it located? O2 sensor is in your exhaust so if uts not in the exhaust thrn no
There is no sensor by this name in a toytota. The Toyota air/fuel sensor is also known as the upstream air/fuel sensor. The Toyota downstream sensor is also known as the downstream O2 sensor.
The air fuel sensor heater circuit is also known as a Oxygen Sensor. It's main purpose is to detect the amount of oxygen in the exhaust gas compared to the outside level of oxygen.

I believe it is inside the Air Meter. It also can be called the mass air flow sensor.
No, it is not a knock sensor at all. An AF (Air/Fuel Ratio) sensor is also know as a wide range oxygen sensor. It is the newer type oxygen sensor.
What will a bad mass air flow sensor cause? Mass Air flow sensor regulates amount of air coming in to the amount of fuel being used. If this sensor is bad you would have either a overly rich or lean fuel condition. Check the fuel pump as mass air flow sensor has no moving parts and rarely goes out.
air/fuel mixture
the Intake Air Temperature Sensor (IAT) could also be called the Manifold Air Temperature Sensor (MAT) some instances they are both.
It's in the exhaust manifold. Be aware that some 99 camry's have air-fuel sensor, others have oxygen sensor instead at the same place.
P1130 indicates an Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction Bank 1 Sensor 1. Problems could be a faulty air fuel ratio, the sensor harness is shorted, the sensor has a poor electrical connection, a fuel pressure problem, a fuel injector issue, or air leaks in the intake.
The MAP sensor measures air flow for your car's computer. The computer uses air flow to set fuel flow for the correct fuel/air mixture.
Yes. Fuel injectors that are worn out can "slobber" fuel into the engine creating a rich mixture. This means to much fuel, not enough air = poor fuel economy. This can also be caused by a very dirty air cleaner, bad Oxy sensor(s), bad mass air flow sensor, carboned IAC valve and a host of other things.
