P0340 OBD Engine Code Logo   Code #P0340 -
Camshaft Position Sensor 'A' Circuit (Bank 1 or Single Sensor)

Select a Code:

Audi A6
Quattro 3.0 engine, car runs fine except when idling there is a slight surge where the rpms go from about 750 to 1,000 and then back down to 750, slight shutter sometimes.

Looks like its a problem with the Camshaft Position Sensor Circuit and could be a problem within the sensor itself, the wiring within the unit or in the PowerTrain Control Module (PCM). You should probably replace the Sensor and at least inspect the circuit and make sure everything is good with the PCM.

havent fixed yet.first thought was fuse.then fuel pump, then timing belt..then I got a dtc at autozone and checked the codes...now I reckon its a fuse or sensor in the circuit, or a new distributor is in order...

Ford Fiesta
my engine light came on and I then put it on the diagnostic and it showed camshaft position sensor P0340, I had the sensor replaced and the car went fine for about 60km then the engine light came back on and the car lost power. I replaced it again and the same problem occurred, strange thing is the car goes well for the first couple of km and then only does it loose power and battle to start and then egine light appears again. I have also checked the timing, and wiring wich seems to be fine, there is also no dirt or sludge causing the sensor to not read properly, don't know what the problem can be, can anyone help

Engine light on,truck start,vibrate,mis fire,overdrive light comes on,p0340 show

Experienced sudden brief loss of power ("cutting out"), usually when accelerating or driving over 60mph. Dodge Neon 2004 51,460 miles. Haven't tried to repair. Wondering if such a low mileage engine could be having timing belt problems simply due to its age. Or, do I simply replace the camshaft position sensor.

Dodge Neon
Experienced sudden brief losses of power ("cutting out"), usually when accelerating or driving over 60mph. Dodge Neon 2004 51,460 miles. Fixed another problem by replacing gas filler cap. This problem seemed to disappear, but reappeared, the last time at lower speeds, ca. 30mph. Starts and idles fine, no vibration, clattering or knocking. Haven't tried to repair. Wondering if such a low mileage engine could be having timing belt problems simply due to its age and my tendency to accelerate hard/drive 90+mph (so not driving). Or, do I simply replace the camshaft position sensor?
