Throttle Valve Switch (TVS) Test (Amigo, Pickup & Trooper 2.6L)

1. Disconnect throttle valve switch. Note terminal identification. See Fig 1 . Check throttle valve switch terminals for proper continuity. With throttle at idle, continuity should be present between terminals "I" and "P", but not between terminals "P" and "F." 2) At wide open throttle, continuity should be present between terminals "P" and "F", but not between terminals "I" and "P."
2. There should be no continuity between terminals "I" and "P" or "P" and "F" with throttle between idle and wide open position. Replace throttle valve switch if defective.
