Throttle Position Sensor Most (TPI) throttle position indicator sensors have extra pins for extra functionality, but for this discussion the three wire design will be discussed. To help explain this, these three leads and their function as it relates to engine and transmission performance are analyzed.
In music, the tonic is the first scale degree of a diatonic scale and the tonal center or final resolution tone. The triad formed on the tonic note, the tonic chord, is thus the most significant chord. More generally, the tonic is the pitch upon which all other pitches of a piece are hierarchically referenced. Scales are named after their tonics, thus the tonic of the scale of C is the note C.
