3.
Connect an analog type ohmmeter between terminals 2 and 4.
Terminal 2: Sensor ground
Terminal 4: Sensor output
4.
Slowly open the throttle valve from the idle position to the fully open position and check that the resistance values change smoothly with the
opening of the throttle valve.
Standard Value...Approx 0.5 Kohm increasing to 3.5-6.5 Kohm
