Test Description

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The number below refers to the step number on the diagnostic table.

3: The throttle valves are spring loaded in a slightly open position and should move in either direction without binding. The throttle valves should always be under spring pressure.

DTC P2101

1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Observe the DTC information. Are DTCs P0120, P0220 or P2135 also set?	-	Go to Diagnostic Trouble Code (DTC) List - Vehicle	Go to Step 3
3	Turn OFF the ignition. Visually inspect the throttle body for the following conditions: Throttle valves that are NOT in the rest position Throttle valves that are binding open or closed Throttle valves that are free to move open or closed WITHOUT spring pressure-Refer to Diagnostic Aids In This Test. Did you find any of these conditions with the throttle body?	-	Go to Step 11	Go to Step 4
4	IMPORTANT: Disconnecting the throttle body connector will cause additional codes to set. Disconnect the throttle body connector. Turn ON the ignition, with the engine OFF. Measure the voltage of the throttle actuator control (TAC) motor control 1 and TAC motor control 2 circuits of the throttle actuator motor with a DMM connected to ground. Is the voltage more than the specified value for both circuits?	11 V	Go to Step 8	Go to Step 5
5	Is the voltage less than the specified value?	2 V	Go to Step 7	Go to Step 6
6	Test the TAC motor control circuit that measured above the specified value for a short to voltage. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 13	Go to Step 8
7	Test the TAC motor control circuit that measured below the specified value for a short to ground. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 13	Go to Step 10
8	Test the TAC motor control 1 and TAC motor control 2 circuits for high resistance. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 13	Go to Step 9
9	Test for a poor connection or terminal tension at the throttle body connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	-	Go to Step 13	Go to Step 11
10	Test for a poor connection or terminal tension at the engine control module (ECM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	-	Go to Step 13	Go to Step 12
11	Replace the throttle body assembly. Refer to Throttle Body Assembly Replacement . Did you complete the replacement?	-	Go to Step 13	-
12	Replace the ECM. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	-	Go to Step 13	-
13	Clear the DTCs with a scan tool. Turn OFF the ignition. Start the engine. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition?	-	Go to Step 2	Go to Step 14
14	Observe the Capture Info with a scan tool. Does the scan tool display any DTCs that you have not diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List - Vehicle	System OK
