Throttle Position (TP) Sensor

Disconnect negative battery cable and TP sensor connector. See Fig 1 . Using ohmmeter, check resistance between indicated terminals. See THROTTLE POSITION (TP) SENSOR RESISTANCE table. If resistance is not as specified, adjust TP sensor.
See ADJUSTMENTS - 1.6L MFI article in this section. If resistance is not as specified after adjustment, replace TP sensor. For further diagnostic procedures, see TESTS W/CODES - 1.6L MFI article in this section.

THROTTLE POSITION (TP) SENSOR RESISTANCE

Application

Ohms

Between Terminals "A" & "B"

With .020" (.50 mm) Clearance At Stop Screw

0-500

With .031" (.80 mm) Clearance At Stop Screw

Infinity

Between Terminals "A" & "D"

3500-6500

Between Terminals "A" & "C"

At Idle

300-2000

At Wide Open Throttle

⁽¹⁾ 2000-6500

⁽¹⁾	There should be more than 2000 ohms difference between idle and wide open throttle readings.
