TPS INSPECTION (SAMURAI)

1. Disconnect TPS connector. Using hand vacuum pump, apply 20 in. Hg vacuum to throttle opener to move throttle lever to idle position. Using ohmmeter, check resistance between upper and lower terminals of TPS connector with proper shim thickness gauge inserted between throttle valve lever and stop screw. see scheme 10 Refer to the «THROTTLE POSITION SENSOR (TPS) RESISTANCE»(ref-25800-S39227436252001010500000) table.
2. If TPS inspection results are not within specification, adjust TPS. Replace TPS if it cannot be adjusted to specification.

Scheme 1

1. Disconnect TPS harness connector and throttle opener vacuum hose. Using hand vacuum pump, apply 20 in. Hg vacuum to throttle opener to move throttle lever to idle position. Insert.012" (.30 mm) shim thickness gauge between throttle lever and throttle stop screw. see scheme 10
2. Connect ohmmeter between terminals "C" and "D" of TPS connector. (Scheme 1) Loosen TPS mounting bolts, and turn TPS fully clockwise. Turn TPS counterclockwise slowly to find position ohmmeter reading changes from infinity to zero ohms. Tighten TPS mounting bolts at that position.
3. Ensure continuity does not exist between terminals "C" and "D" when.016" (0.40 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw.
4. Ensure continuity exists between terminals "C" and "D" when.008" (0.20 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw.
5. If continuity is not as specified in steps 3) and 4), TPS zero adjustment is incorrect. Start adjustment sequence again. If results are the same after readjusting, replace TPS. After final adjustment is completed, reconnect TPS connector and vacuum hose to throttle opener.

TPS INSPECTION (SIDEKICK MPI)

Disconnect negative battery cable. Unplug TPS connector. Using ohmmeter, check resistance between terminals of TPS connector. (Scheme 5) If idle switch check is not within specification, adjust TPS installation angle. See THROTTLE POSITION SENSOR (TPS) RESISTANCE table. Replace TPS if it cannot be adjusted to specification.

TPS INSPECTION (SIDEKICK TBI)

Disconnect negative battery cable. Disconnect TPS harness connector. Using ohmmeter, check resistance between each pair of terminals. See the THROTTLE POSITION SENSOR (TPS) RESISTANCE table. (Scheme 1) If resistances are not as specified, adjust TPS. Recheck resistance between each pair of terminals. If TPS cannot be adjusted to obtain correct values, replace TPS.

TPS INSPECTION (SWIFT DOHC)

Unplug TPS connector. Using ohmmeter, check resistance with selected shim thickness gauges between throttle stop screw and throttle lever. See THROTTLE POSITION SENSOR (TPS) RESISTANCE table. (Scheme 2)and (Scheme 3). If TPS cannot be adjusted to obtain correct values at terminals "C" and "D", replace TPS.

Scheme 3

TPS INSPECTION (SWIFT SOHC)

Unplug TPS connector. Using ohmmeter, check resistance between terminals of TPS connector with proper shim thickness gauge inserted between throttle lever and throttle stop screw. (Scheme 4)and (Scheme 5). See THROTTLE POSITION SENSOR (TPS) RESISTANCE table.
