WARNING: This page is about a different car, the 1997 Suzuki Swift. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect negative battery cable and TP sensor connector. See Fig 1 . Using an ohmmeter, check resistance between indicated terminals. See THROTTLE POSITION (TP) SENSOR RESISTANCE table.
If resistance is not as specified, adjust TP sensor. See ADJUSTMENTS article. If resistance is not as specified after adjustment, replace TP sensor. For further diagnostic procedures, see TESTS W/CODES article.
