RE: 1995 E320 This fuel injection code means voltage supply @ engine control module implausible/low voltage. Does anyone know where to start with that one? All I know is I'm getting AWFUL mileage. It's maybe between 5-10 mpg. Amazingly though, the engine runs fine and accelerates well etc. I've got the correct Bosch plugs in it.
The OVP is relatively new, the 15 amp fuse is intact, and it's a "late model" MB OVP. I also have a code 5 on pin 3 which is an EGR issue which I've had for a few weeks now - still working on that one.
