Throttle Position (TP) Sensor

Measure total and variable resistance between specified TP sensor connector terminals. See Fig 1 . See TP SENSOR TEST TERMINALS  table. Total resistance should be 3500-6500 ohms. Variable resistance should change smoothly between 3500 and 6500 ohms as throttle valve is moved from closed to wide open throttle.
