wat is the sensor on throttle body?

that sensor is the t p s sensor.throttle position sensor.

Take a pic there about 3 sensors on the throttlebody and 2 in the air intake tube next to it

MAF (mass air flow) is there too.. that is the likey square one you saw.

The 2 in the tube is the MAF, IAT. On the throttle body is the TPS, IAC, and sometimes the MAP. All of which can look square or rectangle depending on the viewing angle

most likely map sensor

the tps on mine is on side next to themostat housing mao on top square
