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!

Service engine light means change engine oil. When you change your engine oil have them reset it. Have a nice day

06 Pontiac G6 2.4 I replaced the motor, started right up and ran great. Shut it off, now it won't start. I have no spark, and codes, po366 and po341 showed up. What's common to these 2 sensors?


DTC P0340: Intake CMP Sensor Circuit
DTC P0341: Intake Camshaft Position (CMP) Sensor Performance
DTC P0365: Exhaust Camshaft Position (CMP) Sensor Circuit
DTC P0366: Exhaust Camshaft Position (CMP) Sensor Performance

The five volt reference circuit .

The 4X camshaft position (CMP) sensor circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, low reference circuit, and an output signal circuit. The CMP sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 4-tooth reluctor wheel attached to the camshaft. As each reluctor wheel tooth rotates past the CMP sensor, the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse. The sensor returns a digital ON/OFF DC voltage pulse of varying frequency, with 4 varying width output pulses per camshaft revolution that represent an image of the camshaft reluctor wheel. The frequency of the CMP sensor output depends on the velocity of the camshaft. The ECM decodes the narrow and wide tooth pattern to identify camshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses CMP sensor output information to determine the camshaft relative position to the crankshaft, to control camshaft phasing, and for limp-home operation.

Where is the camshaft sensor located on 1996 Chrysler town and country lxi


Well the sensor should be on the drivers side just under the valve cover and it looks like a circle with a plug in it.I think your problem though is the timing belt is off a tooth it will run fine but being a tooth off will keep that light on.

I have a po340 a po341 an a po016 code on a 2006 dodge caravan want start


Hi !
P0340 = This indicates that a problem was detected in the camshaft position sensor circuit.
P0341 = Camshaft Position Sensor Circuit Range/Performance
P0016 = Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)

The common point of these errors is the camshaft sensor, so I'm afraid you need to visit a service.

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.

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.

Hi, how l fix the code on my vw golf 96 the code is po341 ?


the code po341 is camshaft position sensor is faulty, you will need to replace the sensor locate behind cam gear. I would pick up Haynes auto repair book for 20 bucks, it will give you instruction on camshaft tear down and it has pictures, great tools to have if you planing to do your own work, its not easy tasks and on top of that its time consuming. the part will cost ya 47 bucks.

99 mercedes e320.check engine light on.po341


that appears to be a camshaft position sensor performance code. you can start by checking to see if the sensor is working properly, re-check and make sure that the harness is ok by checking the resistance through the harness if all looks well there make sure the computer has the latest software on it by having it scanned at your local dealer. also you can check the reluctor wheel on the camshaft for damage or debris in the way of the sensor.

hope this helps!

1998 Buick Century 3.1 engine


camshaft position sensor it is located on the engine block on the belt side of the motor there is also a crank position sensor that is located on that same side, that is behind the main belt pulley. basically the computer is sensing that these two sensors are out of sync with each other this is a common problem, and is corrected by replacing the camshaft position sensor in most cases. Otherwise check the connections and wiring to the sensor please rate -jeff
