Honda Civic 2005 EX - P2646
Check Engine Light went on - Code P2646 - When I checked the oil - was three quarts low. Just had the oil change less then a month ago. If the Oil pressure switch needs to be replaced would that cause the buring of oil?

Re: Honda Civic 2005 EX - P2646
1. Fill the oil up to the correct level
2. Reset the ECM/PCM (with the ignition off, pull fuse #6 in the under-hood fuse box for 10 seconds)
3. Turn the car on and hold it at 3000-rpm with no load (in park or neutral) until the radiator fan comes on, then let it idle for a couple of minutes
4. Accelerate in 1st gear to over 5000-rpm and hold for 2 seconds
Did the code come back?
NO- It was the low oil level
YES- I'll tell ya the rest if you need it.
