07 C230 Sport help
Hi new to the forum here. 
..
I hsve a 07 C230 sport which I purchased about a year ago. Recently, within the last couple of months, the vehicle has become extremely inconsistent with starting. What I mean by that is... Sometimes it stars, and sometimes it doesn't. I never know when I go to turn the key. My moms boyfriend (a mechNic) keeps getting an error code that reads P0607. Not sure what that means. Since he doesn't speak English communication is hard. Anyway, any advice on how to get this issue fixed?

Welcome.
P0607 = Control Module Performance. See starting procedure below. With this code the most likely culprit is the CPS (crankshaft position sensor) needing replacement. We hope it's not the ECU.
Also ensure that fuel pressure at the schrader valve on the fuel rail is minimum 3.8 bars WHILE CRANKING.

Hi, Im sorry to bump this thread but I have a similar problem,
My car will start fine but shuts off while driving for no reason, no error codes or anything, had it on star, no luck.
I was planning on replacing the crankshaft position sensor.
car stalls while driving and will restart straight away,sometimes it take a few seconds to restart.
The today after 2 months chasing this problem the car gave a error code:
P0607 Control Module Performance.
I am hoping this is related to the CKP and not the ECU?
Anyone seen anything like this before?
Thanks

fuel pressure at idel 760rpm is 3400-3500 PSI. when u crank the engine it jumps to 3900, then goes back to 3500, engine nearly at full temp.
is this pressure low or ok? when i rev it the pressure increases to 100PSI++++
I am getting these values from a OBDII scan tool
Thanks
edit: ambient air temp is reading -7.6F, would this have anything to do with it? also when i plugged OBD back into car there was another code but its gone now, the code was U1401

Dodge: Implausible Engine Speed Signal Received
Jeep: Implausible Engine Speed Signal Receive
this ^^ is all i could find on the code

Those pressures are definitely wrong as in they cant be that high... you should be seeing 40-50 psi... not thousands! unless you miswrote them. Air temp is also wrong... Hopefully Glyn can get back to this thread and shed some light....

i think fuel pressure could be ok, its a diesel so that's why the pressure is so high. Unfortunately I dont have any equipment to test pressure at schradar valve.
yes the air temp is not right its jumps from the top of the range 80oC to -40oC, but it dont think this would cause a problem, i think the air temp is only an indication and doesn't control anything?? I'm probably worn here
thanks for reply

Oh, a diesel....well that changes things just a bit. I didn't see that written anywhere.
Either way air temp is still not right and it actually is pretty important, second to coolant temp which the engine uses to determine how much to enrich the fuel mixture. Basically, the engine computer is mapped to run at 0% enrichment in the coolant map at normal engine operating temp (this is a coarse adjustment) and then secondly it looks at air temp to help determine the density of the air coming into the engine and trim the mixture further (fine). This works together with the MAF to get a more accurate measure of exactly how much air the engine is ingesting.

Thanks for this information, I didnt know this,
Anyway, i've replaced the CKS (crankshaft position sensor) and so far so good, so hopefully this solves the problem,

Sorry ~ now I've noticed. I did not expect a diesel question in a gasoline thread. I shall be more attentive in future.
