Dirt and small debri will cause this to happen. The sensor is mounted a very short distance from the notches that it reads when the engine is turning.

Hi,

On 2 wire Sensor engines, the distributor stator or Camshaft Position (CMP) sensor is a single Hall effect magnetic switch. This is activated by a single vane, and is driven by the camshaft.

On Three Wire Sensor engines, the Camshaft Position (CMP) sensor is a variable reluctance sensor, which is triggered by the high-point mark on one of the camshaft sprockets.

The Distributor engine does not use a separate CMP sensor. It utilizes a conventional distributor, equipped with a Hall effect device, for this function.

The following symptoms can be caused by intermittent wiring connections or faulty signal to the EMS.
Related Symptoms

  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Stalling on acceleration

My car is showing PO344 (Camshaft Position Sensor A Circuit Intermittent) as a problem it's having... I replaced the camshaft sensor about 2 years ago when I was having a similar problem; could the sensor...


All ways, the camshaft position sensor signal sent to the ECM is intermittent

The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Powertrain Control Module (PCM) or Electronic Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.

When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.

When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

Check thos DTC diagnostic and possible solutions about P0344 - Camshaft Position Sensor Circuit Intermittent

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall

Possible causes
- Harness or connectors (The sensor circuit is open or shorted)
- Camshaft position sensor may be faulty
- Camshaft (Intake) may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead (Weak) battery

Possible solution
- Charge battery
- Repair harness or connector
- Replaced Camshaft Position Sensor.
Tech notes
- Sometimes and in some models, low battery voltage or a weak starter can can trigger a Camshaft Position Sensor code.


Hope this helps.

Information on codes p0016 and p0017; causes and how to fix them.


crankshaft/camshaft position correlation error. Can be caused by slipped timing belt or either sensor manfunction. First thing to do is check connectors on both sensors. If good, then you should check the valve timing by inspecting the camshaft sprocket alignment with timing marks. If you need instructions, please let us know.

Squealing from the top of engine what is it coming from?


See if noise is in what used to be your distributor location. It is called a camshaft synchronizer. The camshaft sensor spins around in this assembly. If it has play in it the sensor will rub on the assembly & cause a squealing noise. It will generaly set check engine light for bad camshaft position sensor. If you buy the synchronizer new it will come with the tool needed to properly install the sensor at its correct position.

1997 nissan quest camshaft sensor where is it & how to replace it


The camshaft sensor is located inside the distributor and is part of it, in order to replace it you must replace the distributor,to replace remove the dist cap. mark the location of the rotor,by marking where its pointing to, then mark the dist housing, so now theres a mark on the rotor and housing to show where rotor points, next mark the location of dist going into housing, mark the shaft and the block,because it spins in block this way you can line back up.next remove hold down bolt and pull out,mark the new dist in exacat same spots as the old so you can install back the same,you may have to put it in and pull it out until your marks are lined up,this way the timing will be dead on, when done you can check timing. good luck

1993 ford taurus, replaced all starting and charging componets still no spark to plugs. Checked all fuses and all fusible links. Replaced key switch, ignition switch,neutral safty...


The camshaft position sensor sends a signal to the PCM, powertrain control module. The PCM then determines spark plug firing. Could be the camshaft position sensor.

1996 is all I have
Camshaft Position (CMP) Sensor 3.0L (2V) Engine
The camshaft position sensor (CMP sensor) (12126):
  • is a single Hall-effect magnetic switch activated by a single vane which is driven by the camshaft (6250).
  • provides camshaft position information which is used by the ignition coil (12029) and the powertrain control module (PCM) (12A650) for fuel synchronization.
3.0L (4V) Engine
The camshaft position sensor (CMP sensor) (6B288) is:
  • a variable reluctance sensor.
  • triggered by the high-point mark on the LH exhaust camshaft sprocket (6256).
-----------------
3.0L (2V) Engine
SPECIAL SERVICE TOOL(S) REQUIRED Description Tool Number Syncro Positioning Tool T95T-12200-A
sth~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Prior to removal of the camshaft position sensor (CMP sensor) (12126), set cylinder No.1 to zero degrees top dead center (TDC) of compression stroke. Then note the position of the camshaft position sensor electrical connector. The installation procedure requires that the connector be located in the same position.
Removal
  1. Disconnect battery ground cable. Refer to Section 14-01 .
  1. Disconnect engine control sensor wiring connector from camshaft position sensor.
  1. Remove camshaft position sensor retaining screws and camshaft position sensor from camshaft position sensor housing.
  1. If removing camshaft position sensor housing from the cylinder block (6010), proceed with Removal Step 5. If not removing camshaft position sensor housing, proceed to installation Step 6.
  1. Remove hold-down clamp (bolt and washer assembly).
  1. Remove camshaft position sensor housing from cylinder block.
Installation
  1. sth~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: A special service tool such as Syncro Positioning Tool T95T-12200-A must be obtained prior to installation of the replacement camshaft position sensor. Failure to follow this procedure will result in improper camshaft position sensor alignment. This will result in the fuel system being out of time with the engine, possibly causing engine damage.
    Attach Syncro Positioning Tool T95T-12200-A as follows:
    1. Engage camshaft position sensor housing vane into the radial slot of the tool.
    1. Rotate tool on camshaft position sensor housing until tool boss engages notch in camshaft position sensor housing.
  1. Pre-lubricate synchronizer gear with engine oil meeting Ford specification ESE-M2C123-A prior to assembly.
  1. Install camshaft position sensor housing so that drive gear engagement occurs when arrow on locator tool is pointed approximately 75 degrees counterclockwise from the rear face of the cylinder block. This step will locate camshaft position sensor electrical connector in the pre-removal position.
  1. Roatate Syncro Positioning Tool T95T-12200-A clockwise slightly. This will engage oil pump intermediate shaft. Push downward while adjusting Syncro Positioning Tool T95T-12200-A until the Syncro Gear engages the camshaft gear.
  1. When synchronizer flange is fully seated against block, the installation tool should be facing counterclockwise of engine centerline approximately 33 to 45 degrees.
  1. Install hold-down clamp (washer and bolt) and tighten bolt to 19-30 Nm (14-22 lb-ft).
  1. Remove Syncro Positioning Tool T95T-12200-A.
  1. sth~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: If camshaft position sensor electrical connector is not positioned properly, DO NOT reposition the connector by rotating the camshaft position sensor housing. This will result in the fuel system being out of time with the engine, possibly causing engine damage. Remove the camshaft position sensor housing and repeat installation procedure, beginning with Step 1.
    Install camshaft position sensor and retaining screws. Tighten screws to 1.5-4.0 Nm (13-35 lb-in).
  1. Connect engine control sensor wiring connector to camshaft position sensor.
  1. Connect battery ground cable.
