Default P0344 code

Yesterday I got the P0344 code, the traction control light goes on engine light goes on and a red )( with a lightning bolt in the middle goes on the jeep shakes and the gas pedal doesn't do anything, anyone have any help or suggestions for a fix maybe even a possible part number? Thanks all!

My biggest question is do I have to flash the computer when I replace the sensor?

No need to flash the computer.

REMOVAL - 3.8L




The CMP (Camshaft Position Sensor) (3) is bolted to front of engine. The CMP uses a pigtail wiring harness (2). This connects the sensor to the engine harness.

1. Disconnect negative battery cable.
2. Disconnect electrical connectors (1).
3. Remove sensor mounting bolt (4).
4. An O-ring is used to seal the sensor to engine. Remove sensor (3) from engine by pulling while rotating.

INSTALLATION - 3.8L




If the removed sensor is reinstalled, clean off old spacer (3) on sensor face. A NEW SPACER (3) must be attached to face before installation. Inspect O-ring (2) for damage, replace if necessary. If sensor is being replaced, confirm that paper spacer (3) is attached to face, and O-ring (2) is positioned in groove of new sensor.

1. Apply a couple drops of clean engine oil to the O-ring (2) prior to installation.


2. Install sensor (3) into engine and rotate into position.
3. Push sensor down until contact is made with camshaft gear. While holding sensor in this position, install and tighten mounting bolt (4) to 14 N·m (125 in. lbs.) torque.
4. Connect sensor pigtail connector (1) to engine harness connector.
5. Connect negative battery cable.
