Conditions for Clearing the MIL/DTC

WARNING: This page is about a different variant/trim than selected.

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.

1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2	Attempt to start the engine. Does the engine start and run?	Go to Step 3	Go to Step 4
3	Observe the Freeze Frame/Failure Records for this DTC. Turn OFF the ignition for 30 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 cycle?	Go to Step 4	Go to Intermittent Conditions
4	Turn OFF the ignition. Remove the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement in Engine Mechanical. Disconnect the 12-way connector. Test the 12-volt reference circuit for an intermittent condition between the engine control module (ECM) and the 12-way connector. Refer to Testing for Electrical Intermittents and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 5
5	Test the low reference circuit for an intermittent condition between the ECM and the 12-way connector. Refer to Testing for Electrical Intermittents and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 6
6	Test the crankshaft position (CKP) sensor signal circuit for an intermittent condition between the ECM and the 12-way connector. Refer to Testing for Electrical Intermittents and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 7
7	Test for an intermittent and for a poor connection at the ECM side of the 12-way connector. Refer to Testing for Intermittent Conditions and Poor Connections and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 8
8	Test for an intermittent and for a poor connection at the ECM. Refer to Testing for Intermittent Conditions and Poor Connections and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 9
9	Remove the intake manifold. Refer to Intake Manifold Replacement in Engine Mechanical. Test the 12-volt reference circuit for an intermittent condition between the CKP sensor and the 12-way connector. Refer to Testing for Electrical Intermittents and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 10
10	Test the low reference circuit for an intermittent condition between the CKP sensor and the 12-way connector. Refer to Testing for Electrical Intermittents and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 11
11	Test the CKP sensor signal circuit for an intermittent condition between the CKP sensor and the 12-way connector. Refer to Testing for Electrical Intermittents and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 12
12	Test for an intermittent and for a poor connection at the CKP sensor side of the 12-way connector. Refer to Testing for Intermittent Conditions and Poor Connections and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 13
13	Test for an intermittent and for a poor connection at the CKP sensor. Refer to Testing for Intermittent Conditions and Poor Connections and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 14
14	Remove the CKP sensor. Refer to Crankshaft Position Sensor Replacement . Visually inspect the CKP sensor for the following conditions: Physical damage Loose or improper installation Wiring routed too closely to the secondary ignition components Excessive air gap between the CKP sensor and the reluctor wheel The CKP sensor coming in contact with the reluctor wheel Foreign material passing between the CKP sensor and the reluctor wheel Did you find and correct the condition?	Go to Step 17	Go to Step 15
15	Visually inspect the crankshaft reluctor wheel for following conditions: Physical damage Improper installation Excessive end play or looseness Refer to Crankshaft and Bearing Cleaning and Inspection in Engine Mechanical. Did you find and correct the condition?	Go to Step 17	Go to Step 16
16	Replace the CKP sensor. Refer to Crankshaft Position Sensor Replacement . Did you complete the replacement?	Go to Step 17	-
17	Install the intake manifold. Refer to Intake Manifold Replacement in Engine Mechanical. Connect the 12-way connector. Install the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement in Engine Mechanical. Clear the DTCs with a scan tool. Turn OFF the ignition for 30 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 18
18	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 in Vehicle DTC Information	System OK
