Test Description

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

The numbers below refer to the step numbers on the diagnostic table.

2: This step verifies that the malfunction is present.
3: This step tests for electromagnetic interference (EMI) on the CKP sensor circuits.

DTC P0336

Step	Action	Values	Yes	No
Schematic Reference: Engine Controls Schematics Connector End View Reference: Engine Controls Connector End Views and Powertrain Control Module (PCM) Connector End Views
1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	IMPORTANT: If DTC P0335 is also set, diagnose DTC P0335 before proceeding with this DTC. 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 3	Go to Testing for Intermittent Conditions and Poor Connections
3	Inspect all of the crankshaft position sensor (CKP) circuits for the following conditions: Wiring routed too closely to secondary ignition wires or components Wiring routed too closely to after market add-on electrical equipment Wiring routed to closely to solenoids, relays, and motors Electromagnetic interference in the CKP sensor circuits Did you find and correct the condition?	-	Go to Step 12	Go to Step 4
4	Test the 12-volt reference circuit for an intermittent condition or shorted to other circuits. Refer to Testing for Electrical Intermittents and Inducing Intermittent Fault Conditions . Did you find and correct the condition?	-	Go to Step 12	Go to Step 5
5	Test the low reference circuit for an intermittent condition. Refer to Testing for Electrical Intermittents and Inducing Intermittent Fault Conditions . Did you find and correct the condition?	-	Go to Step 12	Go to Step 6
6	Test the CKP sensor signal circuit for an intermittent condition. Refer to Testing for Electrical Intermittents and Inducing Intermittent Fault Conditions . Did you find and correct the condition?	-	Go to Step 12	Go to Step 7
7	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 . Did you find and correct the condition?	-	Go to Step 12	Go to Step 8
8	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 Wiring Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 9
9	Remove the CKP sensor. Refer to Crankshaft Position (CKP) Sensor Replacement . Inspect the CKP sensor for the following conditions: Physical damage Improper installation Excessive play or looseness Excessive air gap between the CKP sensor and the reluctor wheel Foreign material passing between the CKP sensor and the reluctor wheel Insufficient fuel Did you find and correct the condition?	-	Go to Step 12	Go to Step 10
10	Inspect the reluctor wheel for the following conditions: Physical damage Improper installation Excessive endplay or looseness Refer to Crankshaft and Bearings Installation . Did you find and correct the condition?	-	Go to Step 12	Go to Step 11
11	Replace the CKP sensor. Refer to Crankshaft Position (CKP) Sensor Replacement . Did you complete the replacement?	-	Go to Step 12	-
12	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 13
13	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
