Conditions for Clearing the MIL/DTC

The control module turns OFF the malfunction indicator lamp (MIL) after 3 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.

DTC P2261

Step	Action	Values	Yes	No
Schematic Reference: Engine Controls Schematics Boost Control System Description: Boost Control System Description
1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	IMPORTANT: This diagnostic assumes that the engine is in satisfactory mechanical condition and able to provide sufficient vacuum to operate the boost control system. Turn OFF the ignition. Review the vacuum schematics in the Boost Control System Description. Refer to Boost Control System Description . Inspect for the following conditions The vacuum lines for any cracking, loose fit, and for the proper connections at the following: The bypass valve actuator The bypass valve solenoid The supercharger intake plenum The engine intake manifold The bypass valve actuator for sticking, binding, or damage The bypass valve lever for damage The bypass valve for sticking, binding, or damage The boost control solenoid for damage Did you find and correct the condition?	-	Go to Step 15	Go to Step 3
3	Disconnect the boost signal hose from the bypass valve actuator. Connect a vacuum gage to the boost signal hose. Start and idle the engine in park. Turn OFF all lights and accessories. Is the vacuum at the specified value?	0 in Hg	Go to Step 4	Go to Step 10
4	Select Boost Control in the Engine Output Controls. Command the Boost Control Solenoid to 0 percent duty cycle with a scan tool. Observe the vacuum gage. Is the vacuum more than the specified value?	15 in Hg	Go to Step 5	Go to Step 8
5	Reconnect the boost signal hose to the bypass valve actuator. Disconnect the inlet vacuum signal hose from the bypass valve actuator. Connect a vacuum gage to the inlet vacuum signal hose. Is the vacuum more than the specified value?	15 in Hg	Go to Step 6	Go to Step 12
6	Turn OFF the ignition. Connect a vacuum pump to the inlet vacuum signal port on the bypass valve actuator. Slowly apply vacuum to the specified value, while observing the bypass valve actuator. Does the bypass valve actuator retract?	18 in Hg	Go to Step 7	Go to Step 11
7	Connect the inlet vacuum signal hose to the bypass valve actuator. Disconnect the boost signal hose from the bypass valve actuator. Connect a vacuum pump to the boost signal port on the bypass valve actuator. Start and idle the engine in park. Slowly apply vacuum to the specified value. Does the bypass valve actuator extend?	20 in Hg	System OK	Go to Step 11
8	Connect the boost signal hose to the bypass valve actuator. Disconnect the boost signal hose from the boost control solenoid. Connect a vacuum gage to the boost signal port on the boost control solenoid. Command the boost control solenoid to 0 percent duty cycle. Is the vacuum more than the specified value?	15 in Hg	Go to Step 14	Go to Step 9
9	Disconnect the boost source hose from the boost control solenoid. Connect a vacuum gage to the boost source hose. Is the vacuum more than the specified value?	15 in Hg	Go to Step 10	Go to Step 13
10	Replace the boost control solenoid. Refer to Boost Control Solenoid Replacement . Did you complete the replacement?	-	Go to Step 15	-
11	Replace the bypass valve actuator. Refer to Bypass Valve Actuator Replacement . Did you complete the replacement?	-	Go to Step 15	-
12	Repair the inlet vacuum signal hose or the port for a restriction or blockage. Did you complete the repair?	-	Go to Step 15	-
13	Repair the boost source hose or the port for a restriction or blockage. Did you complete the repair?	-	Go to Step 15	-
14	Repair the boost signal hose or the port for a restriction or blockage. Did you complete the repair?	-	Go to Step 15	-
15	Connect any disconnected components. Clear the DTCs with a scan tool. Turn OFF the ignition for 90 seconds. Operate the vehicle within the conditions necessary to verify the repair. Did you verify the repair?	-	Go to Step 16	Go to Step 2
16	Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List - Vehicle	System OK
