PCM

DIAGNOSTIC PROCEDURE - P0339-CRANKSHAFT POSITION SENSOR INTERMITTENT

TEST ACTION
1 Ignition on, engine not running.
With the DRBIII®, read DTCs and record the related Freeze Frame data.
Is the Good Trip Counter displayed and equal to zero?
  1. Yes --> Go To 2
  2. No --> Refer to the INTERMITTENT CONDITION  symptom in the Driveability category.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
2 With the DRBIII®, read and record Freeze Frame Data specific to the CKP signal, ECT, RPM, Sync state, vehicle speed, etc.
Turn the ignition off.
With the DRBIII® lab scope probe and the Miller special tool #6801, backprobe the (K24) CKP Signal circuit at the Sensor harness connector.
WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.

Ignition on, engine not running.
Observe the lab scope screen at least 1 minute and then start the vehicle.
Continue observing the lab scope screen for an additional minute.
Were there any irregular or missing signals?
  1. Yes --> Go To 3
  2. No --> Go To 8
3 Visually inspect the related wire harness including the ground circuit. Look for any chafed, pierced, pinched, or partially broken wires.
Visually inspect the related wire harness connectors. Look for broken, bent, pushed out, or corroded terminals.
Ensure the Crankshaft Position Sensor and the Camshaft Position Sensor are properly installed and the mounting bolt(s) are tight.
Refer to any TSBs that may apply.
Were any of the above conditions present?
  1. Yes --> Repair as necessary

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 4
4 Turn the ignition off.
Disconnect the CKP Sensor connector.
Ignition on, engine not running.
Measure the voltage on the (K6) 5 Volt Supply circuit.
Is the voltage between 4.5 and 5.5 volts?
  1. Yes --> Go To 5
  2. No --> Repair the open or short to ground in the (K6) 5 Volt Supply circuit. Use Miller special tool #8815 when checking for an open circuit to prevent PCM harness connector terminal damage.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
5 Turn the ignition off.
Carefully disconnect the Battery (-) Ground cable.
Remove the Crankshaft Position Sensor.
Inspect the Tone Wheel/Flex Plate slots for damage, foreign material, or excessive movement.
Were any problems found?
  1. Yes --> Repair or replace the Tone Wheel/Flex Plate as necessary.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 6
6
NOTE: An intermittent glitch in the Camshaft Position Sensor can cause the P0339 to set.
Turn the ignition off.With the DRBIII® lab scope probe and the Miller special tool #6801, backprobe the (K44) CMP Signal circuit at the Sensor harness connector.
WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
Ignition on, engine not running.Wiggle the related wire harness and lightly tap on the Camshaft Position Sensor.While observing the lab scope screen.Start the engine.Observe the lab scope screen.Are there any irregular or missing signals?
  1. Yes --> Repair as necessary.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 7
7 If there are no possible causes remaining, view repair.
Repair:
Replace the Crankshaft Position Sensor.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
8 Turn the ignition off.
Disconnect the CKP Sensor connector.
Disconnect the PCM connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMINALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.

Measure the resistance in the (K24) CKP Signal circuit between the CKP harness connector and the appropriate terminal of special tool #8815.
Wiggle the wire harness while taking this measurement.
Is the resistance below 1.0 ohm?
  1. Yes --> Go To 9
  2. No --> Repair the open/high resistance in the (K24) CKP Signal circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
9 Turn the ignition off.
Disconnect the PCM connector.
Disconnect the CKP Sensor connector.
Measure the resistance between ground and the (K24) CKP Signal circuit at the CKP Sensor harness connector.
Wiggle the related wire harness while monitoring the resistance value.
Does the resistance stay below 100 ohms?
  1. Yes --> Repair the short to ground in the (K24) CKP Signal circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 10
10 Turn the ignition off.
Disconnect the CKP Sensor connector.
Ignition on, engine not running.
Measure the voltage on the (K24) CKP Signal circuit.
Wiggle the related wire harness while taking this measurement.
Does the voltage ever increase above 5.5 volts?
  1. Yes --> Repair the short to B+ voltage in the (K24) CKP Signal circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 11
11 Turn the ignition off.
Disconnect the PCM harness connector.
Disconnect the CKP Sensor harness connector.
Measure the resistance between the (K6) 5 Volt Supply circuit and the (K24) CKP signal circuit at the CKP Sensor harness connector.
Wiggle the related wire harness while taking this measurement.
Is the resistance below 5.0 ohms?
  1. Yes --> Repair the short to the (K6) 5 Volt Supply circuit in the (K24) CKP Signal circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 12
