Vauxhal Combo 1.7 Z17DTH CDTi - Erratic idle, code P1216 - Fixed #

Posted by Jamie Lambert on January 12, 2011, 10:23 pm

Year of Manufacture *: 2005
Engine Size and Code *: Z17DTH
( Optional) Fault Codes: p1216 fuel pressure control valve malfunction

Hi all
Got the above vehicle in at the moment, wont idle when cold and erratic idle. When it's warm it idles but still a little eratic. Fault coded and got p1216 rail pressure control valve malfunction. Looked at desired fuel pressure which is about 280 bar and actual fuel pressure is anywhere between 150 to 340 bar. when it drops below 150 bar it cuts out, but it starts straight back up again. When you rev the engine to about 2000 rpm the desired fuel pressure reads about 600 bar but the actual can go up to about 850 bar. Its got a denso fuel pump and i was thinking that the control valve on the back of it could be faulty. It hasnt lost any power on the road it's just idle when cold. I havent checked the injector leak off yet i presume you have to take of the rocker cover. Looking in the archieves John Hall and Jim Watson had very similar faults but there is no fix on the post. Any help would be very gratefull.

Regards Jamie

Hi Piotr
Thanks for the reply, do you know if the imv has to be re-adapted to the vehicle?

Hi Piotr
Thanks for the reply, i think i will go ahead and renew the imv. If you've had a similar fault i am fairly certain that the valve will cure it.
