if its what I'm thinking of it determines the air and fuel mixture needed to keep the car running.
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.

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
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.
Measures air and unburnt fuel in exhaust. Tells you computer how to ajust fuel and air mixture.
The P1135 is set when the Engine Control Module detects a heated oxygen sensor heater circuit malfunction. This could be caused by a faulty air-fuel ratio sensor or a faulty engine control module.
Doubtfull, there was not many bikes in 1987 that were fuel injection. If it has carbs it wont need mass air flow meter as the fuel is mixed in the carb, fuel injection spits the fuel directly into the cyl in which case you need air flow sensor to ensure correct fuel/air mixture.
Mass Air Flow sensor that measure the required fuel according to the amount of air passing and the density of it.
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.
