Good evening guys 🇬🇧
I’ve been working working my way through DME codes and have the last two to try & cure. INPA shows the codes as 126 & 127.

Using google translate I get this;
126 - Control of solenoid valve tank leak diagnosis pump short to ground or open circuit

127 - Solenoid valve actuation of the suction jet pump short to ground or line interruption

this obviously indicates both issues being a sensor/electrical issue (I’m a Ford technician by trade) but when googling the suction jet valve it shows an non-electrical valve which is up by the bulk head.
I also tried to find the fuel leak detection pump thing on real OEM and it doesn’t show one under my vehicle unless I’m checking the wrong place, again, just a non-electrical charcoal filter?
Anyone have any suggestions?
Thanks
