Sidekick 1.6L & X-90

Turn ignition off. Disconnect TP sensor connector. Using an ohmmeter, check resistance between specified terminals of TP sensor connector. See the THROTTLE POSITION (TP) SENSOR RESISTANCE table. See Fig 2. If idle switch check is not within specification, go to next step.
Insert 0.026" (0.65 mm) shim thickness gauge between throttle lever and throttle stop screw. See Fig 3. Loosen TP sensor mounting screws. Using an ohmmeter, check resistance between TP sensor terminals "A" and "B". See THROTTLE POSITION (TP) SENSOR RESISTANCE table. See Fig 2. Turn TP sensor fully counterclockwise and then turn it clockwise slowly to locate point where ohmmeter reading changes from zero to infinity. Holding TP sensor at that position, tighten TP sensor mounting screws snug.
Ensure continuity does not exist between terminals "A" and "B" when 0.031" (0.8 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw. See Fig 3.
Ensure continuity exists between terminals "A" and "B" when 0.020" (0.5 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw. Tighten TP sensor mounting screws to 22.8-38.4 INCH lbs. (2.5-4.5 N.m).
If continuity is not as specified in steps 3) and 4), TP sensor zero adjustment is incorrect. Start adjustment sequence again. If results are the same after readjusting, replace TP sensor. After final adjustment is completed, reconnect TP sensor connector.
