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 P0337

Step	Action	Values	Yes	No
Schematic Reference: Engine Controls Schematics Connector End View Reference: Engine Controls Connector End Views
1	Did you perform the Diagnostic System Check - Engine Controls?	-	Go to Step 2	Go to Diagnostic System Check - Engine Controls
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?	-	Go to Step 4	Go to Intermittent Conditions
4	Turn OFF the ignition. Disconnect the engine control module (ECM) connector. Measure the resistance from the signal circuit to the low reference circuit of the crankshaft position (CKP) sensor with a DMM. Is the resistance within the specified range?	460-620 Ω	Go to Step 5	Go to Step 6
5	Test the CKP sensor circuits between the ECM connector and the CKP connector for a short to voltage or a short to ground. Refer to Circuit Testing in Wiring Systems. Did you find and correct the condition?	-	Go to Step 14	Go to Step 9
6	Test the CKP sensor circuits between the ECM connector and the CKP connector for the following conditions: An open A short across the signal and the low reference circuits A high resistance Refer to Circuit Testing in Wiring Systems. Did you find and correct the condition?	-	Go to Step 14	Go to Step 7
7	Test for an intermittent and for a poor connection at the ECM. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring System. Did you find and correct the condition?	-	Go to Step 14	Go to Step 8
8	Test for an intermittent and for a poor connection at the CKP sensor. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems. Did you find and correct the condition?	-	Go to Step 14	Go to Step 10
9	Test for shorted terminals and poor connections at the ECM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems Did you find and correct the condition?	-	Go to Step 14	Go to Step 13
10	IMPORTANT: If the sensor lead is damaged in any way, DO NOT repair the lead. Remove the CKP sensor. Refer to Crankshaft Position (CKP) Sensor Replacement . Inspect the CKP sensor for the following conditions: Physical damage Excessive play or looseness Improper installation Foreign material passing between the CKP sensor and the reluctor wheel Excessive air gap between the CKP sensor and the reluctor wheel Electromagnetic interference in the CKP sensor circuits Wiring routed too closely to secondary ignition components Did you find and correct the conditions?	-	Go to Step 14	Go to Step 11
11	IMPORTANT: If the reluctor wheel is also damaged, replace the CKP sensor and the crankshaft. Inspect the CKP reluctor wheel for the following conditions: Physical damage Incorrect installation Excessive end play or looseness Refer to Crankshaft and Bearings Cleaning and Inspection in Engine Mechanical - 1.6L (L91).Did you find and correct the condition?	-	Go to Step 14	Go to Step 12
12	Replace the CKP sensor. Refer to Crankshaft Position (CKP) Sensor Replacement . Did you complete the replacement?	-	Go to Step 14	-
13	Replace the ECM. Refer to Engine Control Module (ECM) Replacement . Did you complete the replacement?	-	Go to Step 14	-
14	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 15
15	Observe the capture info with a scan tool. Are there any DTCs that have not been diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List	System OK
