I am running out of ideas, i think my car is running in safety boost mode as it wont go above 5 psi ? , I have a code 55, so all is clear, i have reset the ecu again today but still no joy, 5psi?.

I have checked the det sensor and there was nothing wrong with it, but to be on the safe side i done the resistor trick, still only 5 psi. I have disconnected the waste gate control solenoids, still no good, i have checked the engine water temp sensor and that works (fan works on/off with temp rise and fall).

I made a pressure tester to blow up my engine, no leaks anywere so i'm running out of ideas as what to check next?????

So has anyone got any ideas .

 

HELP :wack:

i'll do u a copy

aaronjb, you are god????

 

:rofl: Well last time I checked I was only human ;) Although I do look rather Buddah like I suppose :rofl: :rofl:

 

i checked the solonoid connector feed cable (from ECU) and i didnt have a ground at all, BUT I DID HAVE THE 12 VOLTS? so i cut the ground cable and connected it to a good earth ......and bobs your aunty, it works, i'm back to 14 psi.

 

Interesting - I'm amazed they made that much difference, but I guess they must with boost jets in.. Quite amazing :)

 

You've got 12v because they're pretty much connected direct to the battery btw, but the earth should only be present when the ECU thinks you're safe to have full boost..

 

So.. either the ECU is putting you into safety boost for some reason (though you seem to have eliminated that - code 55, etc..) or there's a break in the wire or circuit in the ECU - you have the diagrams now though so that's 'easy' (ish!) to check :)

 

One thing - worth getting someone to run a ConZult if you can, as I remember my old import used to be stuck in safety boost, but always reported a code 55.. When I checked with a ConZult while driving I found that it kicked up a det sensor fault every time I went around the first corner in my journey ;) Then reset itself as soon as you stopped and turned the ignition back on again.. Took me ages to find that!
