Dodge 2004 Neon SRT4 Diagnostic Manual

TEST ACTION APPLICABILITY
6 NOTE:An intermittent glitch in the Camshaft Position Sensor can cause the
P0339 to set.
Turn the ignition off.
With the DRBIIIt 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?
All
Yes → Repair as necessary.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 7
7 If there are no possible causes remaining, view repair. All
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 TERMI-
NALS 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?
All
Yes → Go To 9
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?
All
Yes → Repair the short to ground in the (K24) CKP Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 10
