Intermittent Starting Issue

[Richiejh]

I've been having an intermittent issue with my 2.0hdi 140. The car always starts when it's cold, but occasionally when it's warm and I crank the engine it will fire once on 1 cylinder then cut out. If I turn the ignition off and try again it starts, if I keep the starter going it will start after a few seconds.

I've connected up diagbox and I get fault code p0341 intermittent which is a cam sensor, it seems likely that this could be the issue, any thoughts?

P0341 Camshaft Position Sensor Circuit Range/Performance

 

Definitely sounds like a cam sensor. These are only about £20 to £30 so worth replacing. We had one go on our C3 and that came up with fault codes P0341, P0342, P0343  (sensor A circuit bank 1 which would be the inlet one) and the engine light on, but after the initial non start would then run but in limp mode. I replaced both cam sensors on the basis if one had failed the other was probably also likely to fail. Note the sensors from Citroen come with seals so no need to buy new ones separately. However, I think there may only be 1 sensor on your car, part no 1920QN but you should use your VIN at the dealer to get the correct part.

 

I posted this in the C3 Common Problems topic:

25. Camshaft position sensor failure - 2010 C3, 1.4 VTI petrol.

This happened on our C3, 15k miles. The engine management light came on, anti pollution message, went in to limp mode so the performance was poor. Fault codes were read as P0341, 0342, 0343 camshaft position sensor A bank 1 or single sensor range, low, high. Both the inlet and exhaust sensors were replaced as I thought if one has failed the other may not be too far behind. On checking, the inlet one gave a resistance measurement between all of the 3 pins and the new and exhaust only did on 2 pins. £47 for 2 sensors, they come with new O-ring seals.

Thanks for the info, I haven't had the warning light on and have never had limp mode. It just seems to randomly not start when it's warm. If the sensor is cheap then I may as well try it.
