Hi this is my first poston this forum. I purchased a elm327 obd adaptor from ebay due to a problem with my ford fiesta 1.4 tdci on a 2008. The powertrain light (yellow cog) keeps displaying on my dash. I then scanned the car using the latest version of forscan and ended up with error codes for all four injectors, displaying short to ground, error for the maf sensor (malfunction), error for IAT (hight input), error for clutch switch (implasuable switch).
The injectors have been changed previosuly which were carried out a local garage to the previous owner in 2011. My first thought was i doubt its the injectors are all short to ground seems a bit odd. So i chnaged the clutch switch as it was the cheapest part, cleaned the maf sensor and IAT sensor. I then measured the output voltage from one of the pins on the IAT connector, which measured around 12v. From looking online the PCM shout only output max of 5V correct right?
I then rescanned the vehicle for fault codes and the only error code which remained was a short to ground in cylinder 2 and the powertrain light still remains, no power at all. I then tried to view the live paramters by selcting what PID i wanted to view, however, after clicking play, a message appers displaying turn car on but its turned on already and i am not bale to view any parameters. From my point obv veiwing the live parameters would show be if cylinder 2 is not owrking corretcly?
Any help would be appreciated, thanks
