Megane 1.6 ' check injection' & df012

alphamax · Feb 28, 2016

Hi folks ,

Have a Renault megane 1.6 with the sagem 3000 injection computer , the check injection message is there and the diagnostic with clip is showing df012 ( sensor feed voltage no.2 ) 2.def internal electrical fault , I know that the throttle body and pedal pentiometer can cause this but I have replaced both but same problem , I forgot to mention also that the car won't start unless I disconnect the middle connector ( brown one ) on the ecu for a second and plug it back in then it will start and each time afterward but when I clear the faults it won't start again , I'm thinking the ecu may be damaged so I would like to know has anyone any advice on this ?

Thanks in advance

What year is your car.

What else did clip show,,is there a diagnostic report associated with the car,,
(Any other faults in any other ecu's or just your injection ECU.)..

If there is a diagnostic report, then fill it in, it will take you to another part of clip.

Clip has a lot of info built in, but you have to follow every screen through,
AS long as tinternet is off, go through every section that comes up. But you must fill everything in, otherwise clip wont help you, it will just confuse you

It's 2005 , yeah I Seen that diagnostic report i must fill it in , I only took the code and checked the interpretation of the fault in the workshop manual which has limited information .
