DIAGNOSTIC PROCEDURE - P0335-CRANKSHAFT POSITION SENSOR CIRCUIT

TEST ACTION
1 Start the engine.
With the DRBIII®, read the CKP SYNC State.
Does the DRBIII® display CKP SYNC state IN SYNC?
  1. Yes --> Go To 2
  2. No --> Go To 4
2 Turn the ignition off.
With the DRBIII® lab scope probe and the Miller special tool #6801, back probe the (K44) Camshaft Position (CMP) Sensor Signal circuit in the CMP 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 Cam Position Sensor.
Observe the lab scope screen.
Look for any pulses generated by the CMP Sensor.
Start the engine.
Allow the engine to idle.
Observe the lab scope screen.
Did the CMP Sensor generate any erratic pulses?
  1. Yes --> Repair as necessary.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 3
3 Turn the ignition off.
With the DRBIII® lab scope probe and the Miller special tool #6801, backprobe the (K24) CKP Signal circuit in the CKP harness connector.

  2. No --> Go To 8
6 Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Disconnect the PCM harness 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 of the (K4) Sensor Ground circuit from the CKP Sensor harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
  1. Yes --> Go To 7
  2. No --> Repair the open in the (K4) Sensor Ground circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
