Right I’ve been doing more digging this morning I cleaned the connectors up real good, I’m Getting open loop from both DCV plugs back to co377, The resistance on each solenoid plug is bang on both about 2.7, From co377 down to the connectors I’m getting open ( when unplugged) how ever as soon...

That’s another thing I learned I have an earlier block so that was why

Yeah mate it didn’t really make sense at first but the more I thought about it and the more you explained the clearer it became, Now I know what we’re trying to achieve, I can say for sure now that by tomorrow evening there will be no ace light illuminated! thanks so much for all the help and no...

Yeah messuring up from underneath the car. Of both DCV plugs. To a unplugged Co377/c0391 if giving me a high ohms reading so I’m guessing more broken wire than corroded plug, I will squeeze along it tomorrow, if not I will crimp a new sure onto wire 2, After the join. If I get a good reading I...

Right mate I’ve got a spot on reading (5.5) on thePCV after swapping it out ( the solenoid) only to then realise that it was heavily corroded, I’m still getting a bad reading on both DCV’s I’ve narrowed it down to 3/4 wires, 2-8 2-14 Going to c0377/c0391 So I’m guessing a bad wire under body...

Right I’ve done a bit more digging, I’ve been unplugging the pressure transducer not the PCV, I unplugged it as 7/13 are the connectors giving me a bad reading, Once unplugged it gave me a open loop reading! I think this means there’s something wrong with my pressure control valve ? Would you agree

9 v is the battery size I will do some more testing mate we will get to the bottom of this haha

Morning mate, right I’ve read the instructions for my multi meter, it says it automatically finds the range, So I just set it to auto and read the connectors, The results are all over the place, but I’ve double and triple checked them, So here goes, I hope I don’t make this sound to complicated...

Just to clarify tho mate I’m still just testing the pins you said in the earlier post, and in the order you said, unplugged / plugged in etc

Yeah mate that makes sense. Let me get my new needles tomorrow and I’ll check it all again and update you on my findings

I have ordered some smaller needles that are coming tomorrow, I’ll do it again tomrrow to double check, the range on my reader is automatic, but it says in the corner (k) or (m) on all of these reading is was showing, I will do it all again tomorrow with the needles, and will update you tomorrow

Right hear goes: C0391 2-8 110.0k ohms 2-14 105.0k ohms 7-13 52.06k ohms C0647 24-23 131.0k ohms 24-22 130.0k ohms 25-27 108.0k ohms I couldn’t test C0377 as my probes wouldn’t fit inside enough to give me a reading, Let me know what you think mate and if I need to test anything else...

Yeah mate I’ve got them all written down, yellow green etc

I’ve just written down all the wire colours (from the table) so I shouldn’t get any mixed up thank you again

I will bear that in mind thank you

Okay mate will check later on tomorrow

Hey bud, My multi meter turned up today, just to clarify when I’m testing, I don’t need the engine running correct? And also do I need to disconnect the battery as we’re measuring resistance? I just don’t want to mess anything up :)

Thanks mate it maybe a few day u til I get back to ya but I’ll be in touch soon mate thanks again

Sweet mate and yes I have access to rave electrical library, we are going to solve this I cannot thank you enough for your help already it’s invaluable

Okay mate it gives me 4 options, main relay on /off Warning lamp on/ off Direct cnt valve 1 and 2 on and off I did the relay on and off and heard it clicking, Then nothing else worked, then we i bridged it I was about to force to warning light off (as before I wasn’t ) But valves one and two...
