Misfire problems P1327 and P0204

Hi everyone.
For a month i’m having misfire problems with my C3 1.4i 54kw/72hp 2003 with 90k kilometres on it. OBD was giving code P1327 and P0204. First code suggest to change coil pack which i did and car was running fine for a day. Than it started to misfire again but this time obd gave only one code: P1327. I also noticed that o2 sensor readings looked a bit off, to me at least and i have no idea if it should be like this:
O2 sensor 1 bank 1 voltage: 0.5-0.9
O2 sensor 2 bank 1 voltage: 0-0.09
Any help would be really appreciated

For P1327, there are 2 possible that I have listed, which depends on the engine fitted. This is where Lexia starts to pay for itself because it knows which engine is fitted to which VIN and only displays the correct description.

P1327 Ignition coil, camshaft position (CMP) sensor - control circuit
P1327 Ignition - Integrated Phase detection


and for P0204 I have 'Injector Circuit/Open - Cylinder 4'


Which would lead me to ask if you have water dripping on the injectors from a leaking screen wash jet?

OBD just give me a new code: P1336 which is something with crankshaft position sensor, could that cause all my problems? Where is it located on my citroen?

The trouble with generic OBD2 is there can be more than one description which can be misleading.

P1336 - Ignition System Misfire Detected

P1336 - Crank/Cam sensor range/performance

That was asked by Citroen-Driver?


The Crank sensor for a TU3 is on the Clutch bell housing and (often) looks like this:



Cam sensor signal is derived from the injector signal.

So i took my car to citroen service and 2 fuel injectors were bad, they changed them and the car has been running like a dream ever since. But everytime i start the car in the morning MIL comes on with code P1327. But car is running without a problem, i don't know what it could be, if i start the car in the day anytime nothing comes on, just the morning when the car is obviously really cold. Anyone could give me some tips?
