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.

Step	Action	Yes	No
Schematic Reference: Engine Controls Schematics Connector End View Reference: Powertrain Control Module (PCM) Connector End Views or Engine Controls Connector End Views
1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Turn ON the ignition, with the engine OFF. Observe the DTC Information with a scan tool. Is DTC P2228 or P2229 set?	Go to Diagnostic Trouble Code (DTC) List - Vehicle	Go to Step 3
3	Turn OFF the ignition for 90 seconds. 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 4	Go to Testing for Intermittent Conditions and Poor Connections
4	IMPORTANT: The connectors for the following sensors are of the same configuration but are not interchangeable. Observe the engine controls schematics for the barometric pressure (BARO) sensor and for the supercharger inlet pressure (SCIP) sensor and note the circuit colors. Inspect the wiring harness of the BARO sensor for the proper connection. Inspect the wiring harness of the SCIP sensor for the proper connection. Did you find and correct the condition?	Go to Step 8	Go to Step 5
5	Test for an intermittent and for a poor connection at the BARO sensor. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	Go to Step 8	Go to Step 6
6	Test all of the BARO sensor circuits for any intermittent shorts or opens. Refer to Testing for Electrical Intermittents . Did you find and correct the condition?	Go to Step 8	Go to Step 7
7	Test for an intermittent and for a poor connection at the powertrain control module (PCM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you complete the action?	Go to Step 8	-
8	Clear the DTCs with a scan tool. Turn OFF the ignition for 90 seconds. 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 9
9	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
