2005 dodge caravan 2.4L p0344

Hi Ricky, I'm glad to help. Below is the possible causes for the P0344 code that you have.



Symptom:
P0344-CAMSHAFT POSITION SENSOR INTERMITTENT
When Monitored and Set Condition:
P0344-CAMSHAFT POSITION SENSOR INTERMITTENT

When Monitored: Engine running or Cranking.
Set Condition: When the failure counter reaches 20. One Trip Fault.
POSSIBLE CAUSES

GOOD TRIP EQUAL TO ZERO
WIRING HARNESS INSPECTION
(K7) 5 VOLT SUPPLY CIRCUIT OPEN OR SHORTED TO GROUND
TONE WHEEL/PULSE RING INSPECTION
CHECKING CKP SIGNAL WITH THE DRBIII
t LAB
CAMSHAFT POSITION SENSOR
(K44) CMP SIGNAL CIRCUIT OPEN
(K44) CMP SIGNAL CIRCUIT SHORT TO GROUND
(K44) CMP SIGNAL CIRCUIT SHORTED TO B+
(K44) CMP SIGNAL CIRCUIT SHORT TO (K7) 5 VOLTS
PCM

Code 1684 means the computer has lost power since the last check, usually from disconnecting the battery.
Code 344 means the cam sensor on bank one is not always sending a signal to the computer. It could be a wiring problem or something with the actual camshaft.

most car washes have a under carrage wash now days.
I bet my money those sensors are exposed to the jet spray from the under carrage spray and causing water to get into the connectors,happens to me all the time but affects my coil system and the engine picks up a missfire,Gary

Installing parts based on a code is not how it is done

The codes do not tell you what is wrong or what to replace

PO344-Camshaft Position Sensor Circuit Intermittent

The sensor just reported a fault code,now you need a shop
with trouble charts to properly diagnose the issue

Could be mechanical

Did you check your camshaft position sensor circuits to see if they were working correctly or test the sensor itself before going out and replacing the sensor?....Didn't think so....

Lesson learned here? Diagnostic Test Codes (DTCs) DO NOT tell you what parts to replace. They only tell you which systems or circuits in your vehicle are not working as they should be. Then it is up to the person diagnosing the car to determine what is actually CAUSING the system or circuit to malfunction......Of coarse, this requires that you must first understand how the system is supposed to work...

Anyway, with some proper diagnosis, I think you will probably find that your cam sensor code (P0344) is being caused by a timing belt that has skipped a tooth (most likely).

Bad wires or connectors in the wiring harness that is losing contact at times can also cause that code. This can be verified by watching the cam sensor signal to the PCM with a lab scope and wiggle-testing the wiring harness to see if the signal drops out.

The cam/crank sync needs to be checked with a scan tool. If the sync PID is switching back and forth between YES and NO, then it is most likely a skipped timing belt. This is usually CAUSED by a bad timing belt tentioner pulley assembly.

Yup! they DO tend to buck a little when the valve timing is not correct!

P0344 Camshaft Position Sensor Circuit Intermittent Check the wire leads to the cam sensor and if that is in working condition, replace the Camshaft Position Sensor.
Thank you for using fixya and good luck. Auto Zone or Part Source will have the part you need and the instructions no how to do it.

1 Inspect Carburetor Dirty and Improperly Functioning Carburetor. 2 Inspect Carburetor Incorrect Carburetor Adjustment. 3 Inspect Carburetor Worn, Faulty or Damaged Carburetor 1 Inspect Carburetor Worn, Faulty or Damaged Carburetor. 2 Inspect Mass Air Flow Sensor Damaged, Loose, or Faulty Mass Air Flow Sensor or Circuit

this is an eng code p0344 CAMSHAFT SENSOR need to replace this will give you long start or no start
