P2119

DTC P2119

Circuit Description

The engine control module (ECM) controls the throttle valve by applying a varying voltage to the throttle actuator control (TAC) motor. The ECM monitors the actual throttle valve position using throttle position (TP) sensor 1 and 2. If the ECM detects the throttle valve did not return to the rest position within a calibrated time, this DTC sets.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P2119 Throttle Closed Position Performance

Conditions for Running the DTC

* The ignition is ON.
* The vehicle speed is 0 km/h (0 mph).
* The engine speed is less than 40 RPM.
* The engine coolant temperature (ECT) is 5-85°C (41-185°F).
* The intake air temperature (IAT) is 5-60°C (41-140°F).
* The ignition 1 voltage is more than 10 volts.
* The accelerator pedal position (APP) is less than 15 percent.
* DTC P2119 runs once per ignition cycle when the above conditions are met for more than 1 second.

Conditions for Setting the DTC

The ECM determines that the throttle valve did not return to the rest position within 560 milliseconds.

Action Taken When the DTC Sets

* The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
* The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.

Conditions for Clearing the MIL/DTC

* The control module turns OFF the malfunction indicator lamp (MIL) after 4 consecutive ignition cycles that the diagnostic runs and does not fail.
* A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
* A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
* Clear the MIL and the DTC with a scan tool.

Diagnostic Aids

The following table illustrates the ECM connector locations:





* Use the J 35616 Connector Test Adapter Kit for any test that requires probing the ECM harness connector or a component harness connector.
* Inspect for a condition in which the throttle valve may have been held open. For example, ice may have formed in the throttle bore causing the throttle valve not to close. Observe the Freeze Frame/Failure Records.
* The throttle valve is spring loaded to a slightly open position. The throttle valve should be open approximately 3-5 percent. This is referred to as the rest position.
* The throttle valve should not be completely closed or open any more than a specified amount.
* The throttle valve should move open and to the closed position without binding under the normal spring pressure.
* The throttle should NOT be free to move open or closed WITHOUT spring pressure.
* The scan tool has the ability to operate the throttle control system using the TP function located in the TAC System menu. This function operates the throttle valve through the entire range in order to determine if the TAC system operates correctly.
* For an intermittent condition, Refer to Intermittent Conditions. Intermittent Conditions

Test Description

Step 1 - Step 7:

Step 8 - Step 18:

Step 19:

The numbers below refer to the step numbers on the diagnostic table.
2. This step determines if the condition exists. A TP sensor DTC may cause this DTC to set.
3. Depending on the condition, DTC P0638, P2100, P2101, and/or P2119 may set individually or together.
8. When the ignition is turn ON, the ECM operates the throttle actuator control motor to verify the integrity of the system prior to start-up. This can be seen by the momentary flash of the test lamp as the ignition is turned ON.
