The web site for Park Place Lexus-Plano, Tx only list one TPS. They appear the same in the repair Manual. I would call a dealer to be sure. There is an sub throttle actuator that may need ohm checking. Resistance is 0.5-1.0 ohm. To check place one probe in the center slot then place the other probe in the slot to the right and check reading, then move the probe from the right side slot to the left side slot. Repeat this with the row of three above the row just tested. All have the same ohm specs.

To adjust the sub-tps use a 0.30mm feeler gauge between the throttle stop screw and the throttle valve gear ( under the sub throttle actuator ) Then connect the ohm meter to the IDL@ and E@ of the sensor. Turn the sensor clockwise until the ohm meter deflects and set screws. Re-check the IDL2 and E2.

0.30mm in place as above = continuity

0.50mm in place = no continuity

PS: any update to the engine hesitation? or is this still part of the work-up? Walt
