P1516

Circuit Description
The ECM monitors the actual throttle blade position using TP sensor 1 and 2. If the throttle blade is open more than the ECM desires by a calibratable amount this DTC will set.

Conditions for Running the DTC
The Electronic Throttle Control (ETC) learn procedure is not active.

Conditions for Setting the DTC
The difference between the calculated and the actual throttle position is more than what is shown in the table.

Action Taken When the DTC Sets
The ECM illuminates the Malfunction Indicator Lamp (MIL) and records the operating conditions in the Freeze Frame on the first drive trip that the diagnostic runs and fails. The vehicle will default to the limp home mode.

Conditions for Clearing the MIL/DTC
^ The ECM turns off the MIL after three consecutive drive trips that the diagnostic runs and passes.
^ A History DTC clears after forty consecutive warm-up cycles in which there are no failures reported of this diagnostic or any other emission related diagnostic.
^ The ECM battery voltage is interrupted.
^ The scan tool clears the MIL/DTC.
