Hello

I'am living in Switzerland and I just bought an ETC 1992 with the 4.9 Engine. Now just a simple question. Fuel is going empty and the display show's me LO what means go to the gasoline station that's ok. But on same time it tell's me on the Monitor a Code "46"?? Somebody can tell me what that means?

Thanks for your help

All the best from Switzerland

Code 46 means you have a left to right bank fueling difference.

Your car has two oxygen sensors one on each side of the engine. The computer compares the output of each sensors against the other and sets a code if the difference exceeds a preset threshold.

Likely causes of code 46 are:

1. Bad injector on one side of the engine.
2. Bad spark plugs.
3. Exhaust or intake manifold leak.

Also check for codes 013, 017, 042, 043, 044 and 045 which are designed to detect a bad oxygen sensor.

Hi

thanks for your quick response. Just one thing, it shows only if the fuel goes empty, I mean if the Fuel shows on the digital board LO. Otherwise I never had this message.

All the best

that is interesting. now and then, my '88 4100 also does the 046 code & the scary SYSTEM FAULT message right about the time the low fuel light comes on.

this usually happens usually when the car is climbing the winding road in the hills with low fuel.

is it possilbe that the pump swallows some air?
my fix is to pull over. shut it down and wait 60 seconds.
upon restart, the 046 is gone.

anyone else?
