Step Action Values Yes No
Schematic Reference:  Engine Controls Schematics 
Connector End View Reference: Powertrain Control Module 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
  1. Start the engine.
  2. Observe the Engine Speed parameter on the scan tool.
Does the Engine Speed parameter increment?
- Go to Step 3  Go to Step 4

  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.
Does the DTC fail this ignition?
- Go to Step 4  Go to Intermittent Conditions

  1. Turn OFF the ignition.
  2. Disconnect the powertrain control module (PCM) connector.
  3. Measure the resistance from the crankshaft position (CKP) sensor signal circuit to the low reference circuit of the CKP sensor with a DMM.
Is the resistance within the specified range?
1,360-1,730 Ω Go to Step 5  Go to Step 6 
5 Test the CKP sensor circuits for a short to voltage or a short to ground. Refer to Circuit Testing .
Did you find and correct the condition?
- Go to Step 14  Go to Step 9 
6 Test the CKP sensor circuits for the following conditions:
  • An open
  • A short across circuits
  • A high resistance

Refer to Circuit Testing .
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 PCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
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 Connector Repairs .
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 PCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs
Did you find and correct the condition?
- Go to Step 14  Go to Step 13

  1. Remove the CKP sensor. Refer to Crankshaft Position Sensor Replacement .
  2. Visually inspect the CKP sensor for the following conditions:
    • Foreign material passing between the CKP sensor and the reluctor wheel
    • Physical damage
    • Improper installation
    • Electromagnetic interference in the CKP sensor circuits
Did you find and correct the conditions?
- Go to Step 14  Go to Step 11 
11 Visually 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 .
Did you find and correct the condition?
- Go to Step 14  Go to Step 12 
12 Replace the CKP Sensor. Refer to Crankshaft Position Sensor Replacement .
Did you complete the replacement?
- Go to Step 14  -
13 Replace the PCM. 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?
