It sounds like a bad plug or the wire is damaged, do a continuity test on the wires to make sure there is not excessive resistance in one of the wires

Whats code po 343


Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall
P0343 Chevrolet Description
The Camshaft Position (CMP) Sensor sensor works in conjunction with a 1X reluctor wheel on the camshaft. The Powertrain Control Module (PCM) provides a 12 volt power supply to the CMP sensor as well as a ground and a signal circuit.
The CMP sensor determines whether a cylinder is on a firing stroke or on an exhaust stroke. As the camshaft rotates, the reluctor wheel interrupts a magnetic field produced by a magnet within the sensor. The sensors internal circuitry detects this and produces a signal which the PCM reads. The PCM uses this 1X signal in combination with the Crankshaft Position sensor 24X signal in order to determine crankshaft position and stroke. This diagnostic for the Camshaft Position sensor tests for a loss of Camshaft Position sensor signal.
Observe that as long as the Crankshaft Position sensor 24X signal is available, the engine will start. The PCM can determine top dead center for all cylinders by using the Crankshaft Position sensor 24X signal alone. The Camshaft Position sensor 1X signal is used by the PCM to determine if the cylinder at top dead center is on the firing stroke, or the exhaust stroke. The system attempts synchronization and looks for an increase in engine speed indicating the engine started. If the PCM does not detect an increase in engine speed, the PCM incorrectly synchronized to the exhaust stroke and will re-sync to the opposite cam position. A slightly longer cranking time may be a symptom of this condition.

This information is used by the Engine 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.

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.

Possible causes
- Harness or connectors (The sensor circuit is open or shorted)

Service engine soon light blinking /car backfiring and missing


If your check engine light is blinking, you can take your car to Autozone, Advanced Auto or other parts house and ask them to get the engine codes. This ios a FREE service. It sounds like your camshaft positioning sensor, Cam Positioning sensor is bad. This is how comuterized systems tell where the cam and crackshaft are to set the timing. It sounds like you have timing issues.

My service engine soon light came on and the error code was p0340, what is it?


Autozone will read the code and give you a print out of the definition for free.

Or you can google p0340 maybe add galant and you will find out what is is.... (camshaft position sensor)

I have a 2000 buick lesabre. The fix engine soon


It NEVER was the camshaft sensor! Unless, you've removed the engine lately, which I doubt.
RUN to Advance Auto Parts and buy a can of "SeaFoam" and add to your gas tank per instructions...drive at least 100 miles and the problem should go away...IF it doesn't you'll have to replace the O2 sensors in the exhaust system...Any good mechanic should be able to do this for much less $$ than the dealership DO NOT go to the dealer for repairs!
Good Luck

Service engine soon light on. failed aircare.showing code po341 .


The service engine light DOES NOT mean change your oil. The change oil or maintence required light means change oil. The service engine light is the same as a check engine light and means that there is something (not always really bad) is going on with your motor and need someone that has a code reader to let you know what the code is. Yes that code is a camshaft position sensor code. It is located on the passenger side of the engine in the "valley" between the two cyclinder heads. Its not too hard as long as you have some tools and some skills. Its easiest to remove the serpentine belt and remove the bolts for the power steering pump. That way you can move the pump a little to gain better access to remove the cam sensor. Just replaced one yesterday on a 99 century. Hope that helps!
