hi guys quick one on fuel injector control pressure sensor

[arthur_clark]

hi guys quick one on injector control pressure sensor ? is i have just fitted a new fuel rail pressure sensor (numbers dont match exactly but the 1 got is supposed to fit a range of numbers ) and my car has gone into limp mode do i have to reprogram it or should it be plug and ply .this is the 1 i got ,,this is my part number (9307Z512A) but this is the number of the one i got .(9307Z508A)

AFAIK its plug n play, what fault code you are getting? Why to replace it at first place?

 

[ajlsl600]

As above if its right part thats it on common rail. Did you try to start it before it was electrically connected
Likely yr going to need to read/note /clear codes

i put the new one in with the electric connector then started it

Why did you change original? Maybe you have a wiring or PCM issue and not sensor after all?

Mystery ......have codes read.

thanks what is the PCM

 

[robin.large]

Pressure Control Module which sends reference 5v signal to the sensor. Sensor then modifies that voltage according to pressure and returns a 'changed' voltage.
So bad sensor, bad connection, bad cable, failed PCM could all potentially generate the same code. I think Century/Star can differentiate.

great thanks for that one, where under the hood might i find the pcm

 

[arthur_clark]

also i have another problem now, just fitted a new ABS sensor and now the dam thing is telling me ABS is inoperative time for a bear me thinks.

Sorry I was thinking different vehicles. Depending on your vehicle the pressure control is more likely part of the Engine Control Unit.
I think I'd be looking for a wiring issue, frayed, chafed etc?

its a w204, 2008 c200 cdi sport

How much fuel in the tank ?, any chance that air is getting in the fuel . Do these suffer saddle tank syndrome ?.

Do you know the engine code.?

Not much help but I have found its often to walk away for a while.
Lots of issues with non merc abs sensors..also rusty ,damaged reluctor rings dont help.

You cannot rely on generic code readers for this car. A universal translation is "Injector Control Pressure Sensor Circuit Intermittent". Does this mean Rail pressure control valve open circuit intermittently?

Possibly quantity control valve open circuit intermittently?

Or does it mean quantity control valve adaptions intermittently go past the limit?

That is the problem here.

What are your symptoms?

new quantity control valve fitted

new quantity control valve fitted

Glad it has sorted the limp mode.
The engine code should be OM6...... something.

 

[alexanderfoti]

It will be OM646
