11.7 - Throttle Position Sensor ( )

Throttle pot has two identical pots. One for gearbox and other for engine ecu.

One end of each pot is grounded by ECU (about 0V) and other end is supplied with 5V from ECU. Middle should be somewhere between 0V and 5V.

However, the idle setting should be 0.6Volts with 2thou gap on throttle body to butterfly.

It can be adjusted by loosening screws. Pot should move smoothly from 0.6V up to about 4.5V (full throttle).

Some correct settings are:

88 MY is .24 V to .40 V
89 MY is .31 V to .36 V
90 MY and later is .57V to .62 V at closed throttle
