While installing the "new" TPS sensor it must swing from right to left freely prior to installing the securing screws (with the spring in the sensor) if you are looking at the TPS from the driver side of engine. In otherwords you must line of notch's inside the sensor properly when installing.
IF you can nick the three wires near the sensor just enough to use a volt meter where you nicked the wire insulation you can take true Installed Readings.
The voltage supplied from ECM to the TPS should be solid 5.0 volts.
At Idle, the Sensor voltage (being sent ECM) should be.6 volt to.99 volt. As you open the throttle this voltage should gradually increase from .6 volt up to 5.0 volts.
This voltage increase must be smooth, not erratic.
IF erratic then replace the sensor.
The highest reading I have been able to read is 3.1 volts.
Note : You may have to re-adjust your Idle using the Idle torx screw which is hidden in the top of throttle body next to the Throttle iLnkage. This screw manually adjusts the sit (idle) position of the Throttle linkage.
