Claim 7
Independent Claim
105 words
A method for adjusting the sensitivity of a throttle position sensor which includes a magnet and a magnetic sensing element, said throttle position sensor including a magnet, a magnetic sensing element, disposed a first predetermined distance from said magnet and a movably mounted flux concentrator, disposed a second predetermined distance from said magnet, said magnet and said magnetic sensing element being rotatably mounted relative to each other; the method comprising the steps of: a) varying said second predetermined distance until the desired sensitivity is attained without altering said first predetermined distance; and b) securing said flux concentrator in place at the location of desired sensitivity.
