Evening ours2012
I was laughing.
Don't know about you but i hate doing anything twice! I really do hope you get a smile out of this
Anyway lets see if i can remember what i said yesterday before being dumped off the site.
It went something like this:-
Apologies for late reply but Sunday presented interventions beyond my control.
Monday got back to the car, and within minutes of opening the bonnet, the postman turned up with the crankshaft sensor I ordered in antisipation. Couldn't help but to suchum and fit the thing before cracking on with the advice recieved so far. (It looked so simple given my knowledge of these things. Whaa) What a bastad to find, let alone remove and refit! If I were a pro I would have known (as i do know) to remove the undertray and access from the bottom. Being the amature I am I followed the book. Thats not strictly true coz the "book" doesnt identify the position of the sensor and advices removing the battery, it's tray and the computer below the tray. AaaaaAAAZGH. TO WHAT END I DON'T KNOW COZ ONCE REMOVED NOTHING IS ANYTHING MORE ACCESSABLE THAN BEFORE. (Renualt's own workshop manual (MR339 available via Diologies) identifies the TDC sensor in the rear right top of the head where the camshaft sensor is.
Anyway found it changed it and found during a test drive that i'd got rid of the kangaroo effect. Hooraaaa.
Short lived joy coz the lack of power is still severe enough that any attempt to go uphill (whatever the gradient) that I had to turn around and find a flat route home. Not easy given where I live. Still, got home alive and finally got to attending to the advised procedures.
The results (that I suggested you might find find amusing) are as follows:-
Backprobed 1 + 3 of the fuel rail pressure sensor. ignition on = 5.0 v
Pulled the plugs one at a time from the follwing sensors:- (in order)
EGR
MAF/Air Temp
Turbo
Fuel pump
Result = no change on any of them.
Placed back probe pins to each of the sensors mentioned ( in the positions given) and recorder the voltages with the ignition on and again with the engine running. The results (that I'm baffled by
which I hope you can make some sense of are as follows:- (ignition on then engine running) Battery voltage ignition on = 12.33. Engine running 14.64.
EGR 0.01 and variable
MAF/Air Temp 5.0 then 12.22
Turbo pressure 5.0 then 9.46
Fuel pump pressure 3.92 then 7.93
I havent been able to access the accelerotor potentiometer (gang 1) yet due to my own disabilies and physical restrictions. Now I'm back where I started by apologising for the late reply....
Thanks again for your help. Enjoy
PS took your lead on writing posts and put this together in notepad and copied it over
