Throttle Position Sensor (Except Swift SOHC With M/T)

NOTE: Swift SOHC with manual transaxle uses throttle switch to detect throttle position. All other models use throttle position sensor.

Disconnect negative battery cable and TPS connector. See Fig 1 or Fig 2 .
Using ohmmeter, check resistance between indicated terminals. See THROTTLE POSITION SENSOR (TPS) RESISTANCE table. If resistance is not as specified, adjust TPS. See ADJUSTMENTS article in the ENGINE PERFORMANCE Section. If resistance is not as specified after adjustment, replace TPS. For further diagnostic procedures, see TESTS W/CODES article in the ENGINE PERFORMANCE Section.
