IMPORTANT: If DTC P0335 is also set, diagnose DTC P0335 before proceeding with this DTC.
  1. Observe the Freeze Frame/Failure Records for this DTC.
  2. Turn OFF the ignition for 30 seconds.
  3. Start the engine.
  4. 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 aftermarket 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 14  Go to Step 4

  1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle .
  2. Remove the starter. Refer to Starter Motor Replacement .
  3. Disconnect the CKP sensor connector.
  4. Turn ON the ignition, with the engine OFF.
  5. Measure the voltage from the 12-volt reference circuit of the CKP sensor with a DMM. Refer to Troubleshooting with a Digital Multimeter .
Does the voltage measure above the specified value?
11.8 V Go to Step 5  Go to Step 13 
5 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 14  Go to Step 6 
6 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 14  Go to Step 7 
7 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 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 and Wiring Repairs .
Did you find and correct the condition?
- Go to Step 14  Go to Step 9 
9 Test for an intermittent and for a poor connection at the engine control module (ECM). Refer to Testing for Intermittent Conditions and Poor Connections and Wiring Repairs .
Did you find and correct the condition?
- Go to Step 14  Go to Step 10

  1. Remove the CKP sensor. Refer to Crankshaft Position (CKP) Sensor Replacement .
  2. Inspect the CKP sensor for the following conditions:
    • Physical damage
    • Loose or 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
Did you find and correct the condition?
- Go to Step 14  Go to Step 11 
11 Inspect the reluctor wheel for the following conditions:
  • Physical damage
  • Loose or improper installation
  • Excessive end play or looseness

Refer to Crankshaft and Bearings Cleaning and Inspection .
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 Control Module References for replacement, setup, and programming.
Did you complete the replacement?
- Go to Step 14  -

  1. Clear the DTCs with a scan tool.
  2. Turn OFF the ignition for 30 seconds.
  3. Start the engine.
  4. 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 - Vehicle System OK
