4-Cylinder Throttle Position Sensor: Legacy
With engine off, disconnect TPS connector. Using ohmmeter, measure resistance between terminals No. 2 and 3 with throttle fully closed. See Fig 1 . Record reading. Measure resistance between terminals No. 2 and 4 with throttle fully closed and then with throttle fully open. Record readings. If readings are not as specified, replace throttle position sensor. See 4-CYLINDER THROTTLE POSITION SENSOR RESISTANCE table.
