Hello guy's and SOS

Welcome Gago1911, hope we can find a solution for you.

Don't start another thread as a duplicate of this one in the Citroen forum though, rather than that, start one as a V6 HDi (2.7?) problem in the Citroen forum with a link to this thread and lock the thread so you don't get posts in two separate threads on the same problem, just confusing that way.

Have you access to the diagnostic machine? Perhaps you could reset all the fault codes and note the conditions present when they reappear?

hello mgain and it was like 57 kmh, 1600 rmp, 83 c... or somthing

This is actually from a Vauxhall but appears to be the same fault as you are seeing, worth a look.

Do you have access to an oscilloscope to read the sensor output waveform?

Gago1911 · Post by **Gago1911** » 01 Oct 2010, 21:46

No I haven't a osciloscope.
which sensor do you mean?

this opel astra guy, I think, have a another problem than I...

From that forum:

P1335 Pump control module; crank position signal absent.
P1635 Glow-plug control module; circuit malfunction in the control signal.
P0725 Engine RPM input; circuit malfunction.
P0400 Critical system malfunction. [Poss. EGR-related; but needs the sub-code to ID exactly.]

Before you do anything else; verify, with a scope, that the crank sensor is producing the correct waveform and that it's reaching the main and pump ECUs uncorrupted.

If both ECU feeds and earths haven't already been done [if not; why not?] then they should be verified first. Feed relay faults are not unknown.

Seems to tie in with your question.

Yes, worth looking at. The resistance between terminals of a good scope is so high it will not affect the ECU response.

Manifold pressure appears higher than expected - maybe cruising with not much acceleration?

Gago, have you confirmed the battery/alternator charging voltage is between 13.5 and 14.8V at 1500RPM?

Hi,

with the battery is everything fine
