I adjusted my TPS with a common digital volt meter (DVM).

You have to have the TPS installed for this adjustment. I believe the proper voltage is around .54 volts. The TPS has (3) wires, but you only need to tap (2) of them, the Blue and the Black (ground).

1) Using a small flat-bladed screwdriver, flip the TPS cover back from over the end where the wires enter the connector body.

2) Using a small pick or fine flat bladed screwdriver, gently pull back the three rubber grommets that surround the wires as they enter the connector body.

3) You need the key in the 'On' position (engine off) to do the adjustment.

4) Connect your volt meter leads, one to the Blue wire, one to the Black (ground)

5) Loosen the 2 bolts like you did already, then slowly twist the sensor either way until the DVM reads the correct voltage.

6) Then tighten the bolts back down without moving the sensor again.
