The throttle position sensor is installed on the drive shaft of the throttle butterfly plate to sense the opening of the

throttle and provide a basis for ECM to judge the intake. There are analog output and throttle switch output.

Use a BNC to banana cable, connect one end to channel 1 of the oscilloscope, the other end of the black plug is

grounded, and the red connector uses a needle to connect the signal line of the throttle position sensor or the throttle

switch signal 1.

Use a BNC to banana cable, connect one end to channel 2 of the oscilloscope, the other end of the black plug is

grounded, and the red connector uses a needle to connect the signal line of the throttle position sensor, or the

throttle switch signal 2. (if it is a throttle switch, you need to connect this test lead).
