Poor continuity through the TP sensor connectors Poor continuity through the TP harness Intermittent open or short inside the TP sensor While accessing the TP V PID on the scan tool, lightly tap on the TP sensor or wiggle the TP sensor connector and harness.

Note that the idle air control valve is closed by the PCM when the throttle plate is opened to prevent excess air from entering the engine.
