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.
