I have a 2006 jeep wrangler2.4 liter with a engine light on and a po344code. Already had cam sensor and crank sensor replaced. New spark plugs and wires. New wiring harness, timing checked and not ran for 8 hours and the outside temperture is timing belt replaced, new coil pack, new IAT sensor. When I first start my jeep after it has below 48 degrees, it will rough idle when r.P.M.'S are over 2000 and the engine light comes on. I then turn engine off and resart my jeep and then it runs fine and the engine light eventually goes out again. Can you please tell me what is wrong?

When Monitored: While cranking the engine and engine running.

Set Condition: When the failure counter reaches 20. One Trip Fault.

POSSIBLE CAUSES

� GOOD TRIP EQUAL TO ZERO
� CMP WIRE HARNESS INSPECTION
� (F856) 5-VOLT SUPPLY CIRCUIT OPEN OR SHORTED TO GROUND
� TONE WHEEL/PULSE RING INSPECTION
� CHECKING CKP SENSOR SIGNAL WITH THE DRBIII� LAB SCOPE
� CAMSHAFT POSITION SENSOR
� (K44) CMP SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE
� (K44) CMP SIGNAL CIRCUIT OPEN
� (K44) CMP SIGNAL CIRCUIT SHORTED TO GROUND
� (K44) CMP SIGNAL CIRCUIT SHORTED TO THE (F856) 5-VOLT SUPPLY CIRCUIT
� PCM

I would suggest checking the wire harness for loose or contaminations. Check the pulse ring. Ensure there are no contaminatios at the CMP sensor.
